Before you begin assembling a heating system for a country house, it is imperative to develop its detailed design. In this case, first of all, you need to decide on the type of equipment needed, as well as make all the required calculations. for a private house, how to choose the right boiler and pipes for mains, what type of wiring will be better in a particular case - read about all this further in the article.

Main design elements

To assemble a heating system in a country house you will need to purchase:

• radiators;

  circulation pump;

  pipes for highways.

You will also need to buy an expansion tank. In modern heating systems, mainly only membrane equipment of this type is used.

What to consider when choosing radiators

When purchasing batteries, you should first pay attention to:

their design features;

maximum working pressure;

power;

number of sections.

Which heating radiator is best for a private home: main varieties

Modern industry produces several types of such equipment. In specialized stores you can find batteries:

cast iron;

of steel;

made of aluminum;

bimetallic.

All these types of heating radiators are quite suitable for a private home. The choice in this case depends mainly on the operational characteristics of a particular system and the financial capabilities of the owners of the building itself.

Cast iron batteries

The main advantages of radiators of this type are low cost and durability. Cast iron batteries are not subject to corrosion and can last faithfully for up to 50 years. In addition, they are undemanding to the quality of the coolant and can easily withstand quite serious pressure in the system - up to 12 atmospheres.

Cast iron models thus have a lot of advantages, and therefore in some cases they can be an excellent answer to the question of which radiators to choose for heating a private home. However, despite the large number of advantages, such batteries are installed quite rarely in residential suburban buildings. The thing is that Soviet radiators of this variety look too old-fashioned. It is almost impossible to fit them harmoniously into a modern interior. In addition, these batteries weigh a lot and can mainly only be used in buildings with very strong walls. For example, they are absolutely not suitable for a house built from foam concrete.

Cast iron heating radiators are suitable for a private home, but when deciding to choose just such models, it is worth keeping in mind that they are not particularly high in efficiency. Such batteries heat up rather slowly, and their heat transfer is not particularly large.

Steel models

Radiators of this type, unlike cast iron ones, warm up very quickly. This makes them simply ideal for heating systems with temperature control. In addition, steel batteries do not weigh too much. Therefore, they can be installed in buildings with walls made of any materials, including foam blocks or SIP panels.

Steel radiators for heating a private house are thus quite suitable. Their only disadvantages are their fragility and inability to withstand significant pressure. The second drawback for a private house usually does not play too big a role. After all, the pressure in the pipes in such buildings is most often not particularly high. If this indicator in the system does not exceed 7-8 atmospheres, you can safely buy steel models. However, you should also pay attention to the quality of the coolant. If an effective water purification system from a well or well is not installed in the house, you should still refuse to purchase such equipment. When using low-quality coolant, such radiators quickly rust and begin to leak.

When answering the question about which radiators to choose for heating a private home, you should also think about purchasing a relatively new type of steel equipment of this type, which recently appeared on the domestic market. We are talking about batteries made of stainless steel. Such radiators can last even longer than cast iron ones, are characterized by high efficiency and attractive appearance. However, such equipment, unfortunately, is quite expensive. Only owners of elite cottages can afford batteries of this type.

Aluminum models

The main advantage of such radiators is their attractive appearance. Aluminum batteries look very modern and easily fit into almost any interior. They are inexpensive, but, like cast iron, they are used extremely rarely in private homes. It's all about their increased demands on the quality of the coolant. In an acidic environment, aluminum reacts very quickly, releasing quite a large amount of gas. And this, in turn, leads to airing of the system and its failure.

Aluminum heating radiators for a private home are therefore only suitable when the lines use a sufficiently clean coolant. As for pressure, such models can easily withstand loads of up to 15 atm.

Bimetallic batteries

When answering the question about which heating radiator is best for a private home, you should think about purchasing a model of this particular type first. Bimetallic batteries are currently perhaps the most popular type of such equipment. The design of radiators of this type includes elements made of two types of metal - aluminum and steel (or copper). Hence their name. The advantages of bimetallic radiators, among other things, include:

ability to withstand very high coolant pressure (up to 35 atm) and water hammer;

attractive appearance;

light weight;

durability (can last up to 25 years).

In general, bimetallic heating radiators are best suited for a private home. Reviews of models of this type available on the Internet clearly indicate this. Country property owners consider such equipment to be of very high quality, easy to install and operate. In appearance, such radiators resemble aluminum ones, but at the same time they are much more reliable. Their design is such that they look like a monolithic product. Since the performance characteristics of such batteries are better than those of aluminum, they cost a little more (about 25%).

Radiators power

When calculating the heating of a private house, you should start by determining this particular indicator. The selection of radiators for a large cottage, of course, should be entrusted to specialists. If the system is assembled in a small one-story private house, this procedure can be carried out independently, according to a simplified scheme.

total area of ​​the room;

necessary compensation for heat loss.

The latter indicator, when using a simplified calculation scheme, is usually defined as 1 kW of power per 10 m 2 of room (or per 1 m 2 100 W). That is, in order to find out which batteries of what capacity are needed in a particular case, you should simply substitute the required value into the formula N=S*100*1.45, where S is the area of ​​the room, 1.45 is the coefficient of possible heat leakage.

Next, let's look at how to calculate heating radiators for a private house using a specific example. This procedure is actually quite easy to perform. For example, for a room 4 m wide and 5 m long, the calculation will look like this:

• 20*100=2000 W;

  2000*1.45=2900 W.

Heating radiators are most often installed under windows. The required number is selected accordingly. Houses with an area of ​​20 m2 usually have 2 windows. Therefore, in our example, we will need two radiators with a power of 1450 W each. This indicator can be adjusted first of all by changing the number of sections in the battery. But, of course, in any case there should be just enough of them for the radiator to fit freely in the niche under the window.

The power of one section in different types of batteries may vary. So, for bimetallic radiators with a height of 500 mm, this figure is usually 180 W, and for cast iron - 160 W.

How to choose a boiler

So, we found out which heating radiator is best for a private home. If desired, for a country building you can choose either cast iron, aluminum, steel or bimetallic batteries. In this case, everything depends mainly on the quality of the coolant, the pressure in the system and the interior features of the premises. However, when drawing up a project, of course, you should determine the characteristics of other necessary equipment. In particular, it is necessary to calculate the boiler power. Modern industry produces four types of such equipment:

gas boilers;

electrical;

liquid fuel;

solid fuel.

These are the types of boilers that are mainly on sale today for heating private homes. How to choose a specific type of such equipment is actually not a very difficult question. Most often they are installed in houses. Installation of them is usually quite expensive. But at the same time, such equipment is quite economical and convenient to use. They are cheap, but are expensive to operate. Therefore, they are most often installed only if there is no gas main near the house.

Solid fuel and diesel heating boilers are used mostly in buildings built in remote areas. That is, where there is no gas supply and no power lines. Such equipment is usually quite expensive and not very convenient to use.

Boilers for heating a private house: how to choose power

In order to determine this indicator, a specialist is usually also hired. You can try to calculate the boiler power yourself only for a small country house. As when choosing radiators, in this case the basis is the fact that 1 kW of boiler power is required per 10 m 2 of room area.

Selecting a wiring diagram

Heating system lines can be laid in different ways. In small country houses, the simplest “Leningradka” or dead-end two-pipe system is usually used. In residential cottages with several floors, a collector circuit is more often used. In one-story houses of a very large area, a very efficient heating system can be installed, called

How to determine the required diameter of lines

When calculating the heating of a private house, you should, of course, calculate this indicator. If the diameter of the lines is incorrectly selected, the system will not work effectively. To buy suitable pipes, you first need to decide:

with the thermal power of the system;

optimal coolant pressure.

The first indicator is calculated by the formula Q=(V*Δt*K)*860, where V is the volume of the room, Δt is the difference in air temperatures indoors and outdoors, K is a correction factor (depends on the degree of insulation of the building and is determined using a special table) .

The optimal speed of coolant movement in the system is 0.36-0.7 m/s. The resulting value of thermal power and the selected pressure indicator should simply be inserted into the table for determining the diameter of the pipes.

As for the material of highways, in our time both in small country houses and cottages, metal-plastic is usually used. However, if desired, you can install steel or even expensive and very durable copper pipes in a private residential building.

Buying a circulation pump

When choosing this type of equipment, you should decide mainly on two indicators:

with working pressure;

with performance.

The second characteristic is calculated by the formula P = 3.6 x Q/(c x ΔT) (kg/h), where ΔT is the difference between the air temperatures outside and indoors, c is the specific 1.6 dimension.

The required pump pressure can be determined by the formula J= (F+R x L)/p x g (m), where F is the resistance of the reinforcement, R is the hydraulic resistance, L is the length of the section, p is the density of the working fluid, g is the acceleration of gravity .

It’s good to sit in a soft chair on long winter evenings and drink tea with lemon, watching the suffering of another Maria from a television series. It’s dark outside, only occasionally the howls of a snowstorm can be heard. The apartment is warm and cozy, you can hear crackling and rustling sounds from the radiator. But this shouldn’t happen! A high-quality device operates silently and heats the air in the room well.

In order not to torment yourself with constant music from the heating system and not to save your property as a result of leaking batteries, let's find out which heating radiators are best suited for an apartment.

Most multi-storey buildings have a central heating system, when the coolant heated in boiler houses or thermal power plants is transferred to the consumer. But the water circulating through the pipes receives many harmful impurities that cause corrosion of devices. Residents often have unstable temperature conditions of radiators and the risk associated with pressure surges in the general heating network. What batteries are best to install for heating in an apartment?

Experts advise choosing devices that can withstand possible troubles with honor:

1. Due to poor-quality coolant, it is advisable to purchase batteries with a special internal coating or with walls made of chemically neutral material. Before buying heating radiators, pay attention to the thickness of the material: you need to choose batteries in which small abrasive particles that get inside cannot wipe the walls.
2. The pressure in the heating systems of large modern houses is usually within 12-15 atmospheres, and in the so-called Khrushchev buildings it does not exceed 6-9. Therefore, when choosing a radiator, make sure that its declared pressure exceeds what is available in the heating system of the house.
3. When choosing a heating battery for an apartment made of a certain material, it is advisable to know whether it can withstand water hammer. Not all radiators emerge from such situations undamaged.
4. The main function of such a device is to heat the room. Therefore, batteries must have good heat dissipation and a normal service life, so as not to have headaches with frequent replacement of heating devices.
5. The modern market is very diverse. You can choose the best radiators with suitable characteristics for heating your apartment.

Types of modern radiators and their differences

Let’s find out how and based on what points you can choose the right heating radiator for your apartment:

• According to the material from which the battery is made. It affects the weight of the device, heat transfer, and relationship to the coolant.
• According to the chosen design and size, based on the area of ​​the apartment, ceiling height, design.
• In terms of power and operating pressure, based on the heating network available in the house.

Now you can name what heating radiators there are for an apartment, characterize them and decide what is best for creating a comfortable climate. Today, manufacturers can offer batteries: made of cast iron, aluminum alloy, steel, bimetallic.

Cast iron radiators

Such radiators first appeared in Russia more than 150 years ago. In the 20th century, cast iron batteries began to be crowded out by more modern competitors, but even today these devices occupy a significant part of the market.
The ageless popularity of these types of heating radiators for apartments is based on their characteristics, which make them ideally suited to the heating networks of multi-storey buildings.

The advantages of cast iron appliances include the following qualities:

• Cast iron batteries do not corrode. Due to interaction with the coolant, the internal walls of the device are covered with a special black sediment, which prevents oxygen from destroying the cast iron. For safety and durability, a persistent coloring composition is applied to the outer surface of the battery.
• Any coolant can be suitable for cast iron radiators. Bringing with it impurities from sand and debris, the liquid can cause irreparable damage to the inside of the device. But not the one made of cast iron. Because it is chemically passive and does not react with various substances, and its walls are thick enough to withstand the invasion of various environments. In addition, such radiators do not seethe and it is very rare to bleed air from them.
• Many consider cast iron appliances to be the best heating radiators for an apartment, which can be perfectly combined with pipes made of any material. Their production pressure starts from 9 atmospheres and can withstand values ​​equal to 20 units. This suggests that such a radiator can easily withstand water hammer.

Take note! The design of the cast iron radiator allows you to remove or add sections. Maintenance in case of repair is also simple; they can be removed, disassembled and the inside cleaned.

Cast iron models have a number of disadvantages:

• This radiator takes a long time to heat up, unlike other similar devices. But it cools down slowly after switching off.
• A battery made of cast iron has a slow heat transfer compared to the same models made of steel or aluminum, which require less coolant to function, and they release heat one and a half times more.
• Radiators also have an impressive weight, for example, one section weighs 5-6 kg. And almost a liter of water is poured into each department. A similar device made of aluminum requires only 0.4 liters.

Whether the traditional design of cast iron batteries can be considered a disadvantage is a moot point. Of course, such a choice is unlikely to be suitable for luxury housing with exclusive interiors. But in rooms designed in loft, Provence, and eclectic styles, it is quite appropriate to place them. Those who wish can also hide their least favorite shapes under various screens and panels. Or purchase for your apartment the best glamorous models of heating radiators, specially created in retro style. Pay attention to the photo.

Aluminum batteries, lightweight, with good heat dissipation, made a real revolution with their appearance on the heating market in the mid-60s of the 20th century.

The heat transfer of such batteries is quite high because aluminum has low inertia. It is possible to regulate the temperature in the apartment. The radiator is lightweight, easy to transport and easy to install; it is possible to independently assemble the required number of sections. The external surface of the battery has a special polymer coating that protects it from mechanical stress.

When deciding which heating radiators are best to choose for an apartment with a closed heating network, you can choose aluminum ones, because they suit any style and have a nice design. There are many interesting models of different heights and lengths, among which you can find ones that suit your taste and income.

But according to reviews from many buyers and the opinion of experts, it was decided that for heating apartments with a common heating system, the choice of such radiators is not entirely successful. There are several reasons for this:

• Aluminum batteries require constant pressure of up to 12 atmospheres. It is unlikely that the heating networks of apartment buildings with periodically uneven pressure and the possibility of water hammer can be suitable for such conditions. And the existing coolant in them causes a lot of reproaches.
• The coolant with oxygen circulating in the heating system is very unreliable for the described radiators. By reacting with aluminum, this gaseous substance can turn into hydrogen, which creates constant noise and air voids in the batteries. This ultimately leads to paralysis of the operation of such a radiator.
• Installation of aluminum batteries eliminates the choice of connecting parts made of steel, copper, and brass. When these metals interact, reactions occur that lead to corrosion of the radiator surface. Surface discharges can also form. Therefore, a mandatory requirement for aluminum batteries is their installation with plastic pipes and grounding.

Having learned the advantages and weaknesses of aluminum appliances, we can say that they are more suitable for apartments and private houses with closed-loop autonomous heating.

The appearance of such radiators, which differs from conventional batteries, initially appealed to many consumers. Instead of massive cast iron sections, the device's lightweight ribbed plates looked like aliens from the Middle Ages. For some consumers, there was no need to raise the question of which heating battery is best for an apartment.

There are two types of steel appliances available:

• panel ones have the form of plates, are unpretentious in operation and simple in design;
• Tubular are a series of steel pipes that quickly heat up and cool down after being turned off.

Advantages of steel radiators:

• They have good thermal conductivity. The thickness of the battery walls is less than that of cast iron, which causes faster heating.
• They have a fairly long service life due to the simplicity of their design.
• Easy to install due to its light weight. And you can connect them to the heating system in several ways.
• The price of panel radiators is cheaper than similar aluminum models. But this does not apply to tubular types, which are much more expensive and are purchased for luxury housing.

Having decided to choose a steel radiator, you need to accurately calculate its power. It will become impossible to purchase additional sections and expand such a battery. A consultant in a store or a specialist installing heating equipment will help you make the necessary calculations and buy the right model.

They have steel radiators and a number of disadvantages:

• Poor corrosion resistance. To avoid this, you need to keep the device constantly filled with water. In its absence, the inside begins to become covered with rust. Therefore, panel steel radiators are not suitable for centralized heating systems, which operate in most multi-storey buildings. They regularly drain coolant both during preventive maintenance and as a result of emergencies.
• May not withstand water hammer. Occurring serious pressure surges in the heating system can cause the battery to lose its shape or burst at the seams. In working condition, they can withstand 6-10 atmospheres. Experts advise using batteries in houses no more than five floors high or in autonomous heating systems.
• On low-quality radiators, the paint may begin to peel off after a few years.

Bimetallic radiators

Radiators, which are an alloy of tubular steel base and aluminum panels, were invented more than 60 years ago. Combining the technical components of two metals created modern heating radiators for apartments, which began to compete with cast iron counterparts.

Any model of such a radiator consists of two parts. The internal part is a steel circuit in which the coolant is located. The outer one is made of aluminum alloy panels that give off heat. The liquid, moving through steel pipes, heats the plates without coming into contact with them.

The combination of the best qualities of two metals: the high degree of heat transfer of aluminum with the long service life of steel - provided radiators with the opportunity to become very popular among homeowners and decide which radiators are better for central heating. Such batteries are produced in the form of monolithic panels without connecting seams, eliminating possible leakage, and devices consisting of separate sections. The second type allows you to increase or decrease the battery area using a system of gaskets and nipples. It is more affordable.

By choosing bimetallic radiators, you receive the following advantages:

• The ability of monolithic models to withstand pressure of 35 atmospheres.
• Compatible with any coolant due to the treatment of the internal surfaces of steel pipes with a special composition.
• Fast heating and high efficiency due to heating of two metals.
• The presence of thermostats that allow you to independently coordinate the temperature.
• Light weight and relative ease of installation complement the stylish appearance.

No matter what shortcomings the heating system has, you can choose bimetallic radiators for your apartment and house. But long-term operation, due to the different expansion coefficients of steel and aluminum alloy, can lead to squeaks in the batteries and a decrease in their durability. Other disadvantages include the high price. But you always have to pay more for quality.

Division of radiators by class

Having found out what types of batteries there are for heating an apartment, they can be classified into several classes according to quality and cost:

• Economy class includes inexpensive models made of cast iron and aluminum alloy.
• The middle class consists of a wide selection of bimetallic and steel structures with reliable performance.
• The premium class consists of models made of stainless steel, designer cast iron devices and some bimetallic structures.

You can visually evaluate which heating radiators are best for an apartment in the photo.

The duration of the heating season in our latitudes is close to 2/3 of the year. The indicator depends on the region, but on average it is about 250 days. For us, all issues related to the efficiency of the heating system are extremely important, which largely depends on the correct choice of its devices.

Let's look at which heating radiators are better and what the different types are. The article presented for consideration describes in detail the criteria for selecting heating devices. For independent home DIYers, we have provided tips from experienced plumbers.

Regardless of the complexity of the heating system, the main task is to maintain the set temperature in the house or apartment. The heating radiator plays a key role in this, carrying out heat exchange between the air in the room and the coolant.

Uniform heating, efficient heat transfer, microclimate maintenance, stable operation - these are the basic requirements for a heating battery.

In residential premises, single, panel or sectional twin radiators are installed that do not emit toxins when heated

The main parameters influencing the choice of a specific model:

• Operating pressure of the system. Depends on whether the device is connected to an autonomous or centralized network. It is arranged on a gravity or forced principle. On average it varies from 3 to 10 bar or in a similar atmosphere range.
• Thermal power. A characteristic required to calculate the thermal power required to heat a room. It is also needed for selecting individual components of sectional batteries. Approximately 1 kW is required to process 10 m².
• Modularity. The quality inherent in prefabricated radiators, which makes it possible to assemble and disassemble the device to suit individual requirements.
• Speed ​​of reaction to tº. More precisely, the ability to respond to changes in coolant temperature. period of time for cooling and warming up.
• Possibility of equipping with automation. Devices that monitor weather conditions and independently eliminate air jams.

The devices now available for sale ensure free circulation throughout the system. They are characterized by corrosion resistance and attractive appearance.

Sectional radiators differ in the shape and size of the sections, ensuring the supply of the required amount of thermal energy

The thermal efficiency of a radiator depends on the energy dissipation surface area. A flat metal convector has a much smaller area compared to a sectional aluminum convector of the same geometric size. Because the latter radiates heat over the entire area of ​​the fins.

Types of modern heating radiators

During Soviet times, the question of which heating battery is better to choose was never asked for a simple reason. The industry produced only two types of them - steel and cast iron. We live in a fortunate time of diversity, technological and environmental excellence.

The global and domestic industry offers a fairly wide range to choose from. There are several signs according to which it is advisable to separate heating radiators.

Radiators can be divided according to materials of manufacture:

• steel panel convectors;
• cast iron batteries;
• aluminum radiators;
• bimetallic radiators.

By design features:

• sectional;
• panel.

Each of these types is best suited for its operating conditions, and therefore has its own nuances. A separate type of heating radiators is highly specialized. These are devices designed to solve one task, often to the detriment of overall functionality.

Conclusions and useful video on the topic

Useful tips from experts will help you understand the choice of heating device:

The best choice of heating radiator can be considered the one that achieves the greatest comfort and coziness. The radiator can be invisible or, on the contrary, be part of the overall design. But the most important thing is reliability and no hassle.

You can tell us about how you chose a radiator to replace old batteries in an apartment or to furnish a new home in the block below. Please write comments, ask questions, share useful tips and photos on the topic of the article. We are interested in your opinion.

Heating radiators are usually used as heating devices in apartments and private houses, and the first question that arises when installing heating systems is which batteries are best to install in the apartment? The answer to this question depends on many factors, and in order to thoroughly understand it, it is necessary to consider the design features and operating conditions of all types of radiators currently on the market.

Today there are four most popular types of radiators:

• Cast iron;
• Aluminum;
• Steel;
• Bimetallic.

Based on the differences in shape and material, each type of radiator has its own characteristics, and it is these that determine their use.

Cast iron radiators

The familiar bulky cast iron batteries painted with paint are becoming a thing of the past. They are being replaced in stores by modern varieties of cast iron radiators, which have not only an attractive appearance, but also reliability, proven over decades.

Features of cast iron radiators:

• Working pressure from 6 to 10 atm., test pressure – up to 18 atm.;
• Can work in systems with any pipes;
• Can be used for a long time in central heating systems with a pH value of 7-9;
• The sectional structure allows you to select the required number of sections, and in case of reconstruction, add or remove them.

Cast iron radiators have a number of advantages. They are slightly susceptible to corrosion - as a result of the initial interaction with water, a black insoluble precipitate is formed on their inner surface, which prevents the penetration of oxygen dissolved in water to the metal. When properly used, the destruction of cast iron pipes from the inside occurs extremely slowly. The radiators are coated with durable paint on the outside and are reliably protected from destruction. Cast iron radiators have extremely low gas formation, they do not bubble, and do not require constant bleeding of air.

One of the main disadvantages of cast iron batteries is their heavy weight, which makes their installation difficult. The disadvantages of cast iron radiators also include inertia - cast iron heats up slowly and cools down slowly, so quickly regulating the air temperature in a room with cast iron radiators is impossible.

Steel radiators

Steel radiators have the shape of a ribbed plate, inside of which there is a hermetically sealed circuit filled with coolant. The large area of ​​the radiators and the ribbed shape of the surface provide good heat transfer and warm air convection conditions. The material is steel, it has almost the same thermal conductivity as cast iron, but the wall thickness of steel batteries is smaller, so they warm up faster. Steel radiators are designed for operating pressure from 6 to 10 atm.

Advantages of steel radiators:

• The shape and appearance allow steel radiators to successfully fit into any modern interior;
• Steel radiators, like cast iron ones, with proper water treatment in centralized heating systems last 15-25 years;
• Can be used in systems with any pipes. Both in single-pipe and double-pipe;
• They have a low price and are easy to install.

Before installing steel radiators, it is necessary to do this - a closed loop does not allow them to be expanded and the thermal characteristics to be changed.

Under high pressure conditions, steel panel radiators may lose their seal. Therefore, you should not use them in houses with more than 5 floors - the system in them is designed for a pressure of more than 6-8 atmospheres.

Aluminum radiators

Aluminum radiators have a neat, compact and modern appearance; they are also sold in the form of stacked sections, so you can choose the optimal number of them, determined by calculation. The height of aluminum radiators also varies, so they can be placed in convenient places in the room. The working pressure of aluminum radiators is from 6 to 12 atm, test pressure is up to 25 atm.

The advantages of aluminum radiators are obvious:

• Have a modern appearance;
• Heat dissipation is high compared to other radiators and can reach 200 W per section;
• Aluminum radiators are much lighter than other types of batteries, making them easy to install;
• You can select the required number of sections;
• On the outside they are protected with a polymer coating that protects the radiators from damage.

The main disadvantage of aluminum radiators is that they can only be used for a long time in closed systems with strict control of the pH of the coolant. In this case, pipes and fittings made of other metals cannot be used. Aluminum is an extremely reactive metal, and when interacting with copper and brass, it forms a galvanic couple, which can cause electrochemical corrosion and the appearance of surface currents. Therefore, to implement coolant supply systems to aluminum radiators, it is better to use plastic pipes and ground the radiators themselves.

In addition, upon contact with fresh, oxygenated water, aluminum reacts, the product of which is hydrogen gas. Gas bubbles entering the system cause unpleasant sounds. Because of this feature, when installing aluminum radiators, it is necessary to provide a gas exhaust system and install a Mayevsky valve.

Based on these features, we can conclude: despite their low price and excellent heat transfer, it is better not to install aluminum radiators in city apartments with centralized heating. If it is impossible to control the quality of the coolant, one cannot be sure of their long service life.

Bimetallic radiators

As the name suggests, these radiators are made of two metals - steel and aluminum, using the advantages of both of these metals. The internal circuit conducting the coolant in bimetallic radiators is made of steel, which allows them to be used in systems with any pressure and with various types of pipes and fittings. The external plates that transfer heat into the room are made of aluminum and, thanks to its high thermal conductivity, perfectly heat the room.

Advantages of bimetallic radiators:

• High working pressure – up to 35 atm;
• Resistance to corrosion at any quality of coolant;
• Low inertia - radiators quickly heat up and cool down just as quickly, and by regulating the coolant supply you can quickly reduce or increase the temperature in the room;
• Attractive appearance;
• Light weight, easy to install;
• Sectional design allowing you to select the desired number of ribs.

The disadvantages include, perhaps, the higher price of bimetallic radiators. This is soon compensated by their reliability and long service life. It should also be noted that when installing bimetallic radiators, it is necessary to maintain distances from the wall, floor and window sill - it must be at least 4 cm.

To summarize, we can say: for installation in an apartment with centralized heating, it is better to choose cast iron or bimetallic radiators, and for low-rise buildings - also steel ones. Aluminum radiators are best used in closed systems connected to a heating boiler, that is, where it is possible to check the quality of the coolant.

The main elements of the heating system in an apartment are radiators or radiators. Their choice determines the reliability of the heating system as a whole, ensuring comfortable indoor conditions and maintaining optimal temperature. Properly selected batteries will also help create a unique interior in the apartment.

Among the aluminum, new-fangled bimetallic, modern cast-iron and even wooden radiators currently available on the market, having studied their characteristics, evaluating the pros and cons, you can choose those heating devices that are suitable only for you. Let's conduct a comparative analysis - which heating radiators are better for an apartment.

What types of heating radiators are there?

Now there are 4 main types of radiators: aluminum, cast iron, copper and bimetallic. Let's figure out which ones are better.

• Bimetallic.

Bimetallic radiator heating radiators are a structure made of steel pipes, on top of which there is an aluminum shell. The main advantage is the ability to withstand high hydraulic pressure. Also, steel is not afraid of the effects of alkali, which is poured into the central heating system to remove scale from pipes.

The aluminum case on top will allow the battery to retain heat longer. Thus, this type of radiator combines the best properties: strength, durability and high thermal conductivity.

Withstands pressure up to 40 atmospheres and retains its characteristics for decades. The only drawback is the high price due to difficult production technology.

• Aluminum.

Aluminum radiators are the most popular in Russia due to their low price, beautiful design, and lightness. They are available in two versions:

1. Cast - monolithic structure made by casting aluminum alloy under pressure.
2. Extruded - an aluminum alloy profile is formed by a press and cut into individual parts. The finished parts are welded together to form a section. The last sections are connected to each other mechanically. The tightness of the structure is ensured by sealing materials.

Increased reliability and mechanical strength are more characteristic of cast batteries. In terms of other characteristics, extruded options are in no way inferior to solid ones.

Note! Under no circumstances should you completely shut off the 2 taps (valves) at the top and bottom of the radiator! In this case, the battery will burst due to pressure.

• Copper.

Copper is an amazing metal that is not afraid of corrosion and is practically not susceptible to chemical reactions. Thanks to the formation of a thin protective layer on the inside of copper products, they receive additional protection from damage without losing thermal conductivity.

In copper batteries, the inner surface of the heat exchangers always remains smooth without scale and deposits.

Heating radiators made of copper are superior to other batteries in terms of efficiency. The thermal conductivity of copper is five times higher than that of cast iron and steel, and 4 times higher than that of common aluminum.

Let's look at the main technical characteristics of copper batteries:

1. The technical properties of copper devices allow them to be installed in systems with both autonomous and central heating.
2. The temperature of the coolant in copper batteries can reach 150 degrees, and the pressure in the system can reach up to 16 atmospheres.
3. Copper radiators can be used in heating systems with liquid and steam coolant.
4. Due to the softness of the metal, a copper heating system is not afraid of water hammer and subsequent depressurization.
5. Copper radiators do not require painting, which simplifies their operation.
6. Copper heating systems are lightweight, making them easier to install.

To be fair, it is worth noting that in addition to the advantages of copper batteries, there is one drawback - the price. But at the same time, the high cost of copper radiators can justify itself with long-term use.

• Cast iron.

Cast iron heating radiators can withstand 10-15 atmospheres. The advantage is their durability - up to 50 years, resistance to water hammer and low demands on water quality.

However, despite the fact that many old houses still have cast iron radiators, they have the maximum number of disadvantages:

1. large mass (each section about 7 kg);
2. low heat transfer;
3. the need for regular washing and external painting.

Cast iron heating radiators require a large volume of water to work well, so they are not suitable for private homes.

Yet the main disadvantage of cast iron batteries is their unattractive appearance. This opinion was formed thanks to radiators produced in Soviet times. Then the main task was to produce a large number of cheap heating devices at the expense of beauty and design.

In addition to the classic appearance of cast iron batteries, there are models in modern design that can compete in the beauty of appearance even with more technically advanced aluminum and bimetallic radiators.

The tall radiators are shaped like statues. This is a narrow device consisting of a section or solid material. Such radiators are called vertical. They fit harmoniously into the interior of any room. Due to their height, radiators do not take up much space.

There are many types of vertical radiators. The most popular are aluminum, bimetallic, steel, copper-aluminum and even cast iron. Vertical radiators can have side and bottom connections.

The photo shows all available types of high-type heating radiators. Before purchasing, you need to decide on the required battery size in terms of height and width. It is also necessary to take into account the thermal power of such a heating device so that it becomes not only a beautiful interior decoration, but also fully functions as an apartment heating radiator.

Vertical high radiators made of aluminum have the form of vertical strips (sections) assembled into one large heater. High heat transfer and low price are the advantages of this type of radiator. But there are also disadvantages. These devices are not suitable for installation in central heating systems due to the low operating pressure.

This also includes steel panel models, which are also not suitable for centralized heating for the same reason. For autonomous systems, aluminum radiators are the optimal solution due to the price-quality ratio.

For central heating, it is better to choose bimetallic or copper-aluminum products. They are quite durable and have high operating pressure.

Separately, it is worth highlighting steel tubular radiators, which represent the premium segment of high-quality German heating devices. They have a chic appearance and excellent thermal power characteristics.

All vertical radiators are installed and mounted into the heating system in the same way as standard ones.

Small radiator radiators

Low heating radiators perform the same function. Namely, heating the room. They can and should be installed directly under the windows. Small heating radiators appeared not so long ago.

Their demand arose with the growing popularity of solid glazing with a low window sill or its complete absence. Low radiators can be installed on the floor or on the wall. This allows us to solve the problem of heating such a room with panoramic glazing of the building.

The selection of low radiators is also not small. You can buy a heating device consisting of a section or a solid panel. The height of these models varies from 12 cm to 30 cm. Like vertical ones, not all low ones are well suited for installation with centralized heating.

Bimetallic, tubular and copper-aluminum radiators are more reliable and have a high maximum operating pressure. It is better to install aluminum and steel models if the house has autonomous heating. All of the above models will fit there.

Beautiful heating radiators

The word “design” is clear to everyone, but no one imagined that in our lives, inconspicuous cast-iron central heating radiators would be replaced by heating devices made not only from different materials, but in beauty and perfection not inferior to works of art, at the same time completely providing heat to our homes.

Today, designer radiators that have an attractive appearance are increasingly used. They are characterized by:

1. impeccable appearance and the ability to decorate any room without resorting to other accessories; the ability to quickly create the desired thermal atmosphere;
2. efficient operation in wet areas; Easy installation that does not require professional skills. However, the technical characteristics of such devices are still inferior to traditional radiators.
3. Beauty does not always coincide with power, however, in small rooms such radiators can serve as the main source of heat, completely heating it. And in large spaces they can serve as additional sources, fitting harmoniously into the interior.
4. It makes no sense to criticize such devices for some imperfections in technical parameters, because their main function is to decorate the room. And then heat it, although manufacturers do not forget about this function and impose strict requirements during design and manufacturing.

• Bench radiators.

These are original space heating devices, which are tubular steel radiators. The devices have about 2 kW of power and can serve as the main heating circuit for the kitchen, bathroom, nursery, dressing room. They are connected in the usual way to the heating system.

Zehnder benches can be distinguished by a wooden seat covering, which is selected individually, have different seat heights, and are easy to clean.

In wet rooms for sports halls, the seat can be galvanized or replaced with a Werzalit profile, which also does not leave scratches. Sitting on such a bench is very comfortable, it is durable and easy to use.

• Stone radiators.

Family workshops Cinier (France) produce exclusive heating devices. Radiators made of natural white stone, first crushed and then restored using a special method, are real works of art.

The stone has the property of radiating heat at low temperatures, maintaining optimal warmth in the surrounding space. Cinier radiators emit heat without emitting harmful substances, maintain oxygen concentration, and do not reduce humidity in the room.

This promotes uniform distribution of heat from bottom to top, and as a result, a feeling of comfort and well-being.

• Glass radiators.

Solaris heaters from a French factory have been producing glass heating radiators for more than 20 years. The principle of operation of such heaters is that one plate of durable glass is connected to a power supply and, when heated, transfers its heat to the second plate, which ensures further uniform radiation of heat.

It is the second plate that has a decorative appearance, is made of durable enameled glass and serves not only as a decoration for the room, but also performs a heating function.

Solaris radiators are available in different colors, power, can be either horizontal or vertical models, or radiators with heated towel rails, and can be made in different weights, heights and widths.

• Wooden radiators.

Designers have not ignored wood either, creating unique versions of designer radiators made of natural wood with built-in heating elements.

They are mobile and look like wall panels or floor decorations. Also available in the form of various clothes dryers or chairs. Alternatively, they can externally imitate bedding for a pet, while simultaneously serving as a heating device.

They come in different capacities depending on the configuration and size, so there is a wide choice.

It is impossible to consider all the variety of designer radiators, the possibilities of translating artistic ideas into a rational channel. But even from this little it is clear that designer radiators, being works of art, do not forget about their main purpose - heating the living space.

How to choose a heating radiator for an apartment

This factor is paramount when choosing a battery, because different levels of water pressure in two heating systems lead to the need to choose different types of devices.

In Russia there are centralized and autonomous heating systems. What is the difference?

In a centralized system, the water pressure is quite high and at the same time inconsistent. This is due to the fact that all batteries are connected to one pipe and are turned on one after another. When starting the heating, the centrifugal pump turns on abruptly, which can lead to water hammer and damage to certain materials.

In general, a centralized system does not spare the devices connected to it. The coolant in it is hard water, which damages metals. In addition, during periods of no heating, metals are subject to corrosion.

To decide which heating radiator is best to choose for an apartment, first of all you need to look at the pressure level at which this or that type of device will function. To heat apartment buildings, you need a radiator operating at a pressure of up to 10 atmospheres. It must also be resistant to water hammer and the negative chemical effects of water.

The best choice for a central heating system would be:

1. The battery is made of cast iron, since it can withstand pressure up to 15 bar, is resistant to pressure surges and does not rust.
2. Bimetallic battery. Its operating pressure limit is 35 for sectional and 100 bar for monolithic structures. This battery is also highly durable and will last a long time.

If we talk about the autonomous heating system that private homes have, then the opposite is true. It consists of two pipes in which the coolant moves in a circle. The pressure level in such a system is 3-5 bar, and the water is less hard and acidic.

For an autonomous heating system, experts recommend aluminum radiators. It is preferable to choose this type because of its high heat transfer. Made of steel, since this is the optimal combination of quality acceptable for a private home, relatively low price and pleasant appearance. Sometimes you can even choose a battery made of cast iron.

Bimetallic models, of course, can also be chosen for a private home, but we do not recommend them due to their high cost, despite the fact that less expensive types in this case will work no worse.

This is the second most important characteristic by which you can choose a heating device. In the store you can specifically learn about the thermal conductivity of each model. And in order to generally navigate the heat transfer of species, it is enough to know the average characteristics:

Heat transfer of one section:

• Cast iron radiator - 100-150 watts.
• Made of aluminum - 80-210 watts.
• Bimetallic - 150-180 watts.
• Total heat transfer of non-sectional radiators
• Steel radiators - 1200-1500 watts.
• Convectors - 150-10000 watts.

In general, aluminum has the highest heat transfer properties. This characteristic of steel is also quite high. You can also choose cast iron. It's not far behind, but the important factor here is that it takes a certain amount of time to warm up.

However, depending on the circumstances, this can also be a plus, because the cooling time of these radiators is also quite long.

Depending on the material from which the radiator is made, it will be able to perform its functions for different periods of time. To understand which heating radiator is best to choose for your home, you can also focus on its service life:

1. Cast iron radiators – up to 50 years;
2. Aluminum - 15-20 years;
3. Steel – 15-25 years;
4. Bimetallic – 20-25 years;
5. Convectors – 10-25 years.

It is clear that in terms of durability, not a single modern material is ahead of the good old cast iron. If a cast iron battery is made conscientiously, from high-quality raw materials and parts, then when buying it, you can count on half a century of uninterrupted operation.

In second place are radiators made of steel and bimetallic, since, as we have already said, they can last up to 25 years. The service life of each specific radiator depends not only on the manufacturer and model, but also on the quality of the water that will be used for heating.

Cast iron radiators have, of course, begun to look a little different lately. Many models have significantly decreased in size and become flat. However, traditionally cast iron batteries are only coated with a corrosion-resistant primer and then painted. Therefore, they are still not particularly attractive.

Aluminum batteries have the greatest number of different styles and methods of external design. In addition to a wide variety of color options, it is possible to choose a model that suits your size. When you need to choose a battery for a limited space, this type will come to the rescue.

Panel-type steel batteries are good because their simple and uncomplicated appearance easily fits into almost any environment. Tubular-type devices, in turn, can have a very original shape and look good in a modern interior.

Among other things, such heating radiators have various practical functions in the apartment space. Bimetallic radiators are also different and very original in appearance and shape. In particular, models with rounded edges fit well into apartments with smooth corners.

If you are going to connect the battery to the heating system while it is in operation, you will have to turn off the water. You can disconnect only your apartment from the system by turning the valves on the risers. If such valves are not installed in your apartment, then use a riser that turns off the heating in the house, since there is no other way out.

It is good to install a radiator when the heating is on in the house because you can monitor its reaction to pressure and check its integrity. If you carry out the installation with the heating turned off, then with the onset of the season you should pay attention to how the device works.

To understand which heating radiator to choose for a house or apartment, find out what type of connection is right for you:

• Side connection, the most popular type. It is characterized by a pipe supply to the battery on one side and installation to a vertical riser. In this way, the coolant is supplied from above, and discharged from below.
• The bottom connection should be chosen correctly if the apartment does not have vertical risers. When the pipes are hidden under the floor, a radiator with such a connection is mounted directly to the wiring.
• The top connection has a similar principle of operation, but is rarely used, as it leads to poor heating of the bottom of the heating battery.
• With a diagonal connection, water is supplied from above, and drainage is made from below and on the other side. Due to the route of water movement, in this case, uniform heating of the radiator is achieved with minimal water consumption.

It is also necessary that the center distance of the radiator corresponds to the distance between the supply pipes in your apartment. This figure, measured in millimeters, varies depending on the model. To choose the right heating device, you need to compare its indicator with the one you need.

For apartments it is not recommended to: install steel panel-type radiators, since they have a fairly low operating pressure of only 6-8 atm, whereas in a centralized heating system the pressure can reach 10 atm, which can lead to deformation of the collector.

In apartments with central heating, it is recommended to use bimetallic and cast iron radiators, which are the most resistant to corrosion and have a long service life.

The correct choice of heating batteries is not only comfort, but also tangible savings in the foreseeable future. After all, the hour is not far when all apartments with central heating will be equipped with heat meters.

What heating radiators are best to install in an apartment? There are only four options, and if you look, the choice comes down to two.

Possessing high heat transfer, low price and modern design, such radiators have a number of disadvantages that make them unsuitable for use in central heating. They are quite demanding on the quality of the coolant and untreated water quickly corrodes them from the inside.

Aluminum heating radiators are extremely sensitive to water hammer. Read about what this is and how to avoid it in the article about the pressure reducer. The main drawback is that aluminum “cannot stand” contact with other metals.

By wedging batteries into an existing system with metal pipes, you risk having to do repairs soon. Moreover, not only in your apartment, but also with your neighbors downstairs.

They are slightly more expensive than aluminum ones, but this does not save them from the same disadvantages: sensitivity to pressure changes and water quality. Steel tolerates the ingress of oxygen especially poorly. After several summer seasons, even high-quality steel batteries can rust through.

This doesn't mean that steel radiators are bad. They are ideally suited for autonomous heating systems, where they can last for many years (just like aluminum ones). But in apartments with a centralized system it is better not to install such heating radiators.

Surely, many immediately imagined the old “accordions” that were installed in most apartments some 20 years ago. I hasten to reassure you, modern cast iron radiators differ from “Sovdepov” ones both in appearance and characteristics.

There are entire designer series that will fit perfectly into the classic interior of your apartment. And, of course, you no longer have to paint them every year. Thanks to the use of modern powder paints, radiators retain their appearance for decades.

The heat transfer of cast iron batteries of the “new generation” is twice that of their predecessors. Due to its chemical passivity, cast iron does not care about water quality, changes in temperature or pressure in the heating system, and corrosion will make itself felt in at least 40-50 years.

The only problem that has not yet been “conquered” is the weight of cast iron radiators. They're still heavy-duty, so don't even expect to hang them on drywall. But there are models that provide for installation on legs, without mounting to the wall.

The best choice for an apartment. As the name suggests, these batteries are made up of two metals. Inside, such a radiator has an alloy close to steel, which perfectly withstands all the tests of central heating. And on the outside it is coated with aluminum, giving it increased thermal efficiency and excellent appearance.

The only drawback of bimetallic batteries is their price, which is higher than all previous options. However, due to their characteristics, they will be much more economical to operate, so this choice is completely justified.

Thus, it is best to install bimetallic or cast iron heating radiators in an apartment. And it is better to leave steel and aluminum for individual heating systems.

What are the best bimetallic heating radiators?

Such batteries are distinguished by the following characteristics:

1. Structurally - monolithic and sectional.
2. By material - bimetallic and semi-bimetallic.

According to reviews and performance characteristics, the bimetallic option is better, but the semi-bimetallic one is somewhat cheaper. In semi-bimetallic batteries, the coolant is in contact with aluminum surfaces, which leads to a shorter service life.

Separately, it should be noted bimetallic models with a copper core. They work ideally in autonomous heating systems where the coolant is antifreeze. Aluminum-steel batteries quickly fail in such an environment.

There is no clear answer to the question which bimetallic heating radiators are better, monolithic or sectional. Sectional ones are convenient because you can calculate the battery power yourself, and if necessary, add or remove sections. But sectional batteries have a shorter service life. This is due to corrosion at the joints.

True, repairs are not difficult to do: specialized companies quickly replace the leaky section, and it is not as expensive as replacing the entire radiator with a monolithic version. By the way, the price of a monolithic structure is 20 percent more than a similar sectional one.

The coolant can be water, steam, antifreeze and oil, at operating temperatures up to 120°C. Working pressure is usually up to 18 atmospheres. The average service life of bimetallic heating radiators is approximately 25 years, although many companies promise much more, and judging by the reviews, these are not empty words.

Advantages of bimetallic radiators:

• Fits into any design;
• do not take up much space;
• have a wide range of sizes and colors;
• There are models for vertical installation, without the use of brackets;
• are not afraid of high acidity and low-quality coolants;
• withstand pressure surges up to 35-37 atmospheres;
• have high heat transfer;
• equipped with a thermostat to regulate the heating temperature;
• repairable.

Disadvantages of bimetallic radiators:

1. low quality coolant significantly reduces their service life;
2. different expansion coefficients of aluminum and steel over time provoke the appearance of squeaks and reduce the strength and durability of the radiator;
3. the cost of bimetal batteries is higher than cast iron, steel and aluminum products.

You need to choose only products from trusted companies that are professionally involved in the production of heating systems. Such companies use modern technology and conduct testing before consumer use. The total service life of leading companies reaches 40–50 years.

The best bimetallic heating radiators are considered to be Italian. The products of the Sira company stand apart. It was this company that developed the first bimetallic batteries, and today it is the world market leader.

Also of good quality are products from the brands “Global Style” and “Radena”. According to customer reviews, Italian models are durable, compact, and elegant in appearance.

German manufacturers are not inferior to Italians either. Very good reviews about bimetallic radiators from Kermi. These are quite expensive products, but if you incur such expenses, then there is no point in saving.

At an affordable price you can buy a radiator from the Italian brand “Radiatori 200”. The reason is that it has not yet been promoted, and the batteries themselves are semi-bimetallic.

If you need an option with a copper core, then Mars batteries from South Korea are a good choice. They are not too expensive and of high quality. Polish copper-steel radiators from the Regulus-system company are also suitable for autonomous heating systems, in particular, they are good for coolants such as antifreeze.

Russian bimetallic radiators are not so popular, although they cost three times less than their Italian counterparts.

The Tenrad bimetallic radiator was developed in Germany, but is produced in China. It should be noted that this is one of the best offers in the economy segment, and also has a 10-year warranty. Reviews are mostly positive.

Let's consider which type of aluminum radiators is better: cast or extruded.

Molded-type radiators have a higher cost. During their manufacture, each section is cast under pressure from an aluminum alloy - silumin. This alloy contains up to 12 percent silicon (for strength).

All connections of individual elements are made by welding in an inert gas environment. The manufacturability makes the radiators durable. Radiators of the required thermal power are formed from individual sections.

Their advantages:

• Reliability and tightness of connections.
• Possibility of modification by adding or subtracting sections.

Their disadvantage is their higher price.

To reduce the cost of producing aluminum radiators, the extrusion method was used to manufacture the central part. The part is not cast, but extruded in an extruder at high pressure.

Then it is pressed into place with the upper and lower manifolds (they are cast). Often, a composite adhesive is used to join the battery parts together, which makes the finished product even cheaper. The extrusion radiator cannot be disassembled.

Their advantages:

1. Made from recycled aluminum, they have slightly higher heat output.
2. The internal volume of one section is two or one and a half times less than that of a cast radiator.
3. Less weight due to thinner ribs.
4. Low price.

Their disadvantages:

1. The battery cannot be disassembled for repair or modification.
2. The weak point is the connection between the collector and the section. A leak can often appear here. Either the glue won't hold up, or the Teflon or rubber O-rings will wear out.
3. Sometimes these radiators crackle due to temperature differences.

Molded radiators are more reliable. And if you look from this side at which aluminum heating radiators are better, then it is best to give preference to products made by casting. Extruded ones usually have thinner walls and withstand lower operating pressure.

You can take a closer look at extrusion radiators if finances are significantly limited or the low weight of products and coolant savings are essential. Just when purchasing any radiator (both molded and extruded), be sure to choose a reliable brand.

• Italian manufacturers.

The best companies in this segment are Global, Sira, Ferroli. Can also be called Calidor and Faral. Radiator models produced by Italian manufacturers are distinguished by stylishness, elegance of form and excellent finishing. The price of one section is from 350 to 700 rubles (approximately). Now about the properties.

1. The heat-resistant enamel coating does not crack even from boiling water.
2. The inner surface of the products is especially durable and well processed, often even having a polymer coating. This is great - then no corrosion will definitely eat the aluminum.
3. Good pressure indicators (16-20 bar).

• Russian manufacturers.

Here the first place has long been firmly occupied by RIFAR. Note that it makes some radiators under license, which are a complete copy of models from the Italian manufacturer Global. Withstanding operating pressures up to 20 bar, they have a very attractive design.

And if you ask which company’s aluminum radiators are better suited to the harsh Russian conditions, you won’t have to wait long for an answer. Naturally, domestically produced, and more specifically, from the RIFAR company. The price of one “Rifar” aluminum section is about 400 rubles.

• Chinese manufacturers.

The most famous and responsible manufacturers are Konner and Bilux. Their products can be called a budget option, costing 350 rubles and less (per section).

By the way, many well-known brands sell licenses for their products to China, so today it is quite possible to buy both inexpensive and very high-quality Chinese radiators. When purchasing them, follow two simple tips:

1. Carefully study the characteristics of the radiator indicated in the passport. If they are not listed there or there is no passport at all, refrain from purchasing.
2. Buy radiators only in a specialized store, and certainly not on the market. This way you will have a guarantee, which may come in handy (who knows).

When buying these heating devices, remember that any aluminum radiator, even the most “promoted” manufacturer, is afraid of water with a high pH level. In no case should it exceed 7.5 units. Therefore, it makes sense to install heating devices made of aluminum only if the quality of the coolant in the system meets these requirements.

The first place in the rating of heating radiators among aluminum products is occupied by the Royal Thermo Revolution 500 model (Italy).

Sectional heat exchanger with a power per section of 181 W. Bottom and diagonal connection diagrams are possible. Maximum pressure – 20 bar. The coolant volume per section is 370 ml. Based on reviews, the model of the German panel radiator Kermi FTV 22 500 was unanimously recognized as the best steel heat exchanger.

At the maximum permissible pressure and temperature of the coolant (110°C; 10 bar), the panel power reaches 5.8 kW. Bottom connection to CO. The model can be used in a central heating system. The most popular cast iron radiator among our compatriots is the STI Nova 500 heat exchanger.

The battery power can reach 1.2 kW. Lateral connection. Working pressure 15 Bar. Permissible temperature 150°C. The best bimetallic heating radiators, according to users and most experts, are Rifar Monolit 500 sectional heat exchangers.

The maximum operating pressure is 100 bar, the permissible coolant temperature is 135°C. The battery power depends on the number of sections and can be 2.7 kW. Wall mounting, possibility of bottom and diagonal connection to CO.

• Global ISEO 500.

The radiator has high heat transfer rates. A two-stage painting method was used, thanks to which the appearance remains unchanged for many years.

The width of each section is 8 centimeters, such compactness allows it to occupy a minimum of space. The maximum coolant pressure in the network is 16 bar, not the highest figure, but it is still sufficient for using a radiator in both apartment buildings and individual residential buildings.

Main advantages:

1. double protective coating;
2. high heat transfer;
3. compactness;
4. possibility of connecting up to 20 sections.

Cons: None identified.

• Rifar Alum 500

Radiator from a domestic manufacturer. It has a unique design of vertical channels: the holes in each section are sealed not by welding, but by plugs. They, as well as special rubber gaskets between the sections, allow you to use not only water, but also antifreeze as a coolant.

Heat transfer is high, while the dimensions of the radiator are very small. The maximum operating pressure is 20 bar, a fairly high figure.

Main advantages:

1. Pleasant and ergonomic design
2. High heat dissipation
3. Excellent anti-corrosion and chemical resistance
4. Compactness

Cons: The quality of painting on the corners of the sections leaves much to be desired.

• Thermal RAP-500

They have fairly high heat transfer, good anti-corrosion treatment and painting. Maximum operating pressure is 24 bar.

Main advantages:

1. high corrosion resistance;
2. good heat dissipation;
3. easy installation
4. compactness
5. ergonomic stylish design

Main advantages:

1. Energy efficiency.
2. Increased heat transfer.
3. High reliability due to the use of alloying additives.
4. High quality painting.
5. Aerodynamic DREAMLINER design.

Cons: Sensitive to water quality.

The choice of heating equipment with a center distance of 500 mm for the rating was not accidental. The vast majority of modern residential premises have fairly large window openings, and the distance between the window sill and the floor is, as a rule, at least 60 cm.

Therefore, bimetallic radiators of this qualification are in greatest demand.

• Royal Thermo PianoForte 500.

Many positive user ratings for this Italian radiator on Yandex.market, which fully confirm the reliability of the design, long service life, and original design, put it in first place in the rating.

Advantages:

1. heat output from 740 W to 2590 W (depending on the number of sections);
2. the number of sections varies from 4 to 14;

4. steel collectors are designed for pressure surges in the system up to 30 atmospheres;
5. resistant to the most aggressive coolants;
6. wall and floor installation possible;
7. original design;

Disadvantages: quite high cost.

In general, as the British say, we are not rich enough to buy cheap things. Therefore, in this case, the price corresponds to the quality.

Particular emphasis is placed on the presence of Power Shift technology - the presence of additional fins on the vertical manifold, which significantly increase the heat transfer of the model. In addition, in addition to the basic white and black colors, the buyer can order other tones or RAL palettes.

• Rifar Monolit 500.

A domestic development that deservedly ranks second in the ranking in terms of the number of laudatory reviews collected in its favor. Features include the technology of the same name used in the production process - sections are connected using contact-butt welding.

Disadvantages: simple design.

In general, this is a minor disadvantage due to the fact that this model is a continuous water chamber. But there is an internal anti-corrosion coating, as noted by the owners of this radiator, and a stroke pattern that prevents airing of the system.
