Radiators are the main elements of a heating system that organize the flow of heat transfer from the coolant to the environment. It is they who are entrusted with the task of warming up the premises by releasing up to 90% of the total volume of heat released during the operation of electrical elements (electric furnace) or fuel combustion (boiler room, stove heating of private houses). Initially, the bulk of sectional heaters were cast from cast iron, which has good strength properties and immunity to temperature changes. However, such systems had a lot of flaws, since thick walls and discontinuities (in the form of pores, cavities and other casting defects) led to low operating efficiency or rapid destruction of such structures.
Today, in addition to improving the process of producing cast iron batteries, radiators made from the following groups of metals are widely used:
- aluminum is the most energy-efficient type, having extremely low susceptibility to coolant, corrosion and light weight.
- bimetallic - like aluminum models, they have high heat transfer, increased strength and light weight, as well as neutrality to the chemical composition of the coolant.
- steel - made mainly in the form of panels, have average energy efficiency, but are subject to corrosion due to constant interaction with water.
People who are familiar with the properties of a particular material, as well as those who follow the range of manufacturing companies, usually do not have problems choosing radiators for their home or apartment. However, the bulk of consumers are “pioneers” of this segment, and they know about the principles of choice only by hearsay. Moreover, over the past 5 years, this market category has almost doubled, acquiring hundreds of new models of stacked batteries, as well as the opening of a number of new companies. Therefore, having carefully examined the current assortment, we have compiled for you a rating of the best heating radiators, the purchase of which will not only increase the efficiency of the heating system, but also a profitable investment of your own funds.
The best bimetallic heating radiators
Bimetallic radiators have good heat transfer and can withstand high pressure. The combination of two metals makes this heater resistant to water hammer with a pressure of about 150 atm. The main disadvantage is that the system must be constantly filled with coolant. In addition, these heaters are somewhat more expensive than others.
The most popular and best manufacturers of bimetallic heating radiators are the companies “Global” (Italy), “Rifar” (Russia), Sira (Italy) and Royal (Italy).
3 Sira RS Bimetal 500
Better heat dissipation. Silent operation
Country: Italy
Average price: 5,640 rub.
Rating (2019): 4.5
SIRA RS BIMETAL 500 is a high-quality bimetallic sectional heater, the heat output of which is 201 W. Such a good indicator is mainly due to the successful design of the product, and therefore, in a large assembly, it is capable of heating up to 40 square meters of room.
The advantages of SIRA RS BIMETAL in reviews include a pleasant design, high-quality powder coating and reliability in all aspects of operation. True, the operating pressure is not particularly high - the battery can withstand up to 40 bar, but this is enough for installation in apartments with a centralized heat supply, and in private houses with an independent heating source. Among the minor drawbacks, one can highlight only the sensitivity of the bimetal to the composition of the coolant, although, let's be honest, the consequences of such influences are negligible. Otherwise, this heater seems to be a very good option for purchase, combining many positive aspects.
2 Global STYLE PLUS 500
High build quality. Popularity with users
Country: Italy
Average price: 6,400 rub.
Rating (2019): 4.8
One of the brightest representatives of the Global company, included in the rating due to its balanced operational parameters and their good combination with the asking price. The first thing that catches your eye when studying the documentation for STYLE PLUS is a solid warranty period of 25 years. All this clearly indicates the high reliability of the radiator and the manufacturer’s confidence in its product.
In a standard assembly (consisting of 10-12 sections), this heater is capable of delivering up to 2280 W of heat into the environment, which, according to the company’s experimental calculations, is suitable for fairly spacious rooms with an area of 30 to 37 square meters. The maximum permissible operating temperature of the coolant in the system can reach 110 degrees Celsius, and the pressure cannot exceed 35 bar, and therefore prefabricated radiators are recommended for use only in central heating systems.

1 Rifar Monolit 500
The best ratio of price and quality. Operating pressure 100 bar
Country Russia
Average price: 5,100 rub.
Rating (2019): 4.9
The main advantage of the bimetallic heating radiator Rifar Monolit 500 is its low cost on the market with characteristics identical to its main competitors in the rating. The maximum heat output can reach 2744 W, which is enough to heat rooms up to 27-29 square meters. An important feature of the heater is the ability to operate at a pressure of 100 bar, which allows the sections to survive water hammer and maintain operating conditions for a long time.
Reviews of the Rifar Monolit 500 often include statements regarding a 25-year factory warranty. It is worth saying that this information is true, and the Rifar company is very scrupulous about the quality of the entire range of its products. Other advantages of the model include 135 degrees of permissible operating temperature, pleasant design, and a minimum of 210 milliliters of water per section for normal operation.
The best aluminum heating radiators
Aluminum radiators are the most popular type of heaters today. The service life of such heaters can reach 15 years, due to their resistance to corrosion. They are lightweight, easy to install and have an attractive appearance, however, they can withstand less pressure and are sensitive to the composition of the coolant.
3 Thermal RAP-500
Best price. Maximum operating pressure 24 bar.
Country Russia
Average price: 3127 rub.
Rating (2019): 4.6
The domestically produced radiator from Thermal is distinguished by the lowest price in the segment, but in terms of performance parameters it is practically not inferior to the recognized leaders of the category. The most important advantage of RAP-500 is the high specific heat transfer of the section, equal to 252 W. This is the largest indicator in the rating, indirectly indicating the high efficiency of the entire installation. Coupled with decent thermal endurance (the coolant temperature in this case can be up to 130 degrees Celsius), it will not be difficult for the assembled radiator to heat rooms with a total area of up to 50 square meters.
Despite such excellent performance, users note the ill-conceived design of the Thermal RAP-500, although such sharp attacks (from a purely operational point of view) have no good reason. Among the other parameters of the radiator, it is worth highlighting the ability to operate at increased pressure in the system (about 60 bar), which makes it possible to install it not only in apartments, but also in private houses with individual heating.
2 Rifar Alum 500
Maximum operating temperature 135 degrees.
Country Russia
Average price: RUB 2,442.
Rating (2019): 4.7
Another representative of the Rifar company was included in the rating due to a set of good performance characteristics, although with a slight increase in the purchase price. This heater is designed to work with coolants with temperatures up to 135 degrees Celsius and pressures up to 20 bar - an ideal set of parameters for installation in apartments with centralized heating.
In terms of heat output, Rifar Alum 500 is slightly inferior to its competitors: one section is capable of generating up to 183 W of heat. In total (if there are 14-16 elements in the assembly), such a battery will be effective in a living space of up to 26 square meters. It is noteworthy that for the section to function properly, the required amount of water is 270 milliliters, which suggests that the efficiency of the radiator is not the highest. However, with the exception of this nuance, there is nothing more to complain about here: consumer reviews speak of the excellent reliability of the model, compactness and convenient method of wall mounting.
1 Global Vox 500
The optimal choice for the Russian climate. 10 years warranty
Country: Italy
Average price: 680 rub.
Rating (2019): 4.9
Despite their southern origin (Global production is located in Italy), Vox series radiators are perfect for heating systems in the harsh climatic conditions of Russia. They have one of the highest heat transfer rates (up to 195 W), which in practice translates into significant savings on the number of sections during assembly. In addition, Global aluminum products are famous for their low inertia, which allows you to quickly heat a room or optimize temperature parameters.
The Italian manufacturer is aware of the features of Russian heating systems and has taken care of the reliability of its radiators. They are made by injection molding from high-quality aluminum alloys EN AB 46100. The structure is reinforced with solid ribs on the sides, and a 2-stage painting technology is used. The devices are so high-quality that they can be installed in heating systems with an operating pressure within 16 atmospheres (the norm according to SNIPs is no more than 12 atmospheres at the level of the 10th floor and above) with a permissible short-term jump of twice as much. Destruction occurs only at 48 atm, so residents of a house with such radiators are protected from breakthroughs for at least 10 years - this is the official guarantee of the company. There are no complaints about the appearance of the equipment - thanks to a good choice of colors, it fits perfectly into the interior and even serves as its decoration.
The best steel heating radiators
Steel radiators are more often used in apartment buildings and small cottages. The main advantage of this type of heaters is their low cost due to cheap materials and well-established production. In addition, such heaters require less coolant and take up virtually no space, but their heat output is slightly lower than other types.
3 Purmo Compact 22,500
The highest heat transfer rate (5572 W). Possibility of heating rooms up to 50 square meters. m.
Country: Finland
Average price: RUB 7,302.
Rating (2019): 4.8
In the segment of steel heating radiators, there is a surprisingly even selection of options in terms of characteristics. Often, as in this case, the whole difference between them lies only in the price parameters. Purmo Compact 22 500, in a sense, became a “victim” and “hostage” of the company’s pricing policy, which did not respond in a timely manner to competitors’ price reductions.
The configuration of the dimensions of this panel is almost identical to the opponents (500x102 millimeters), and in terms of the nominal parameters of pressure in the system (10 bar + 13 bar test pressure) and coolant temperature (110 degrees Celsius) it does not differ much from the nominal. True, the heat transfer efficiency here is quite high: 5572 W, which allows you to heat up to 50 square meters of area. A small nuance that greatly influenced the ranking in the rating was the question of the quality of the exterior finishing of the Purmo Compact. User reviews contain information about the gradual yellowing of the coating, as well as not always a clear fit of the elements to each other, which is why significant gaps form in the panel.
2 Buderus Logatrend K-Profil 22,500
Nice design. Work with coolant temperatures up to 120 °C
Country: Germany
Average price: 4,720 rub.
Rating (2019): 4.9
The Buderus Logatrend K-Profil 22 500 panel kit is inferior to the segment leader solely in the cost component, compared at the cutoff of performance characteristics. Possessing the same length-to-thickness ratios, as well as the maximum system pressure (10 bar), this sectional heater allows the circulation of coolant at temperatures up to 120 degrees Celsius, thereby compensating for some deviations in the operation of the heating system.
As for the opinions of users, they often notice the equally good appearance of the panel, the ease of its installation and further operation. A small nuance is that the metal of the radiator is sensitive to the composition of the coolant, which can lead to accelerated wear of the battery long before the warranty period expires. The opposite cases also occur (an increase in the working resource), but this is either the merit of the consumers themselves, or individual features of the water in the system.
1 Kermi FKO 11,500
Optimal combination of price and quality
Country: Germany
Average price: 4,520 rub.
Rating (2019): 4.9
Panel heater Kermi FKO 11 500 is the most budget-friendly solution to the issue of purchasing a metal heater. And it’s worth noting that it’s not in vain. Despite the low cost, this model has very solid energy efficiency indicators. With a length from 400 to 3000 millimeters, its heat output can range from 459 to 3441 W, respectively. And, as a result, the ability to heat rooms up to 34.9 square meters.
With a maximum panel length, Kermi FKO 11 500 requires 8.1 liters of coolant to reach its nominal parameters. The operating pressure at peak can reach only 10 bar, however, this quantitative indicator is enough to withstand rare water shocks in the system. Kermi FKO is distinguished by its good design - consumers love to note this positive feature in their reviews.
The best cast iron heating radiators
3 Viadrus Styl 500/130
Great design. High quality product
Country: Czech Republic
Average price: RUB 26,647.
Rating (2019): 4.7
The Viadrus Styl 500/130 heating radiator is the most expensive model in the rating, but at the same time it is very popular among consumers due to its excellent external design and high standards of performance. The peak temperature of the coolant here can reach up to 115 degrees Celsius, leaving a small reserve in case of changes in pressure parameters in the circuit, which is not uncommon for central heating. In general, the pressure can reach up to 12 bar, and the pressure test can reach 18 bar, which is a completely normal result for cast iron batteries.
Judging by consumer reviews, the only truly serious nuance of Viadrus Styl is the coolant flow rate parameter. Due to the thin-walled design (designed to increase heat transfer), one section requires up to 800 milliliters of water to operate effectively. This is not critical for residents of apartments with central heating, but for private owners it results in the need for periodic maintenance of the system (for example, adding water to the expansion tank).
2 Conner Modern 500
Good heat transfer performance. The optimum ratio of price and quality
A country: Germany (manufactured in China)
Average price: 3,860 rub.
Rating (2019): 4.8
The sectional cast iron radiator Konner Modern 500 is an even greater waste of coolant than the previous representative of the rating, but has much better energy efficiency parameters. For normal operation of one section, 900 milliliters of water are needed here, however, such indicators are explained by the increased dimensions of the installation and the notorious thin-walled design. Due to this, for example, a 12-section radiator is capable of heating up to 27-30 square meters of room, which is the most optimal result in the selection.
In terms of operating pressure in the system, Konner Modern 500 has a standard value of 12 bar, and is used primarily for installation in apartments with central heating. The main prerequisites for popularity among users in this case were not only the performance parameters, but also the price, averaged against the background of the total number of representatives of this segment.
1 STI Nova 500
Best price. The most popular cast iron radiator
Country: Italy
Average price: 7,420 rub.
Rating (2019): 4.8
Of course, one of the best cast iron radiators for installation in an apartment (and one of the most inexpensive) is the domestically produced model STI Nova 500. With small overall dimensions, this heater provides heat output at the level of 1200 W, which is enough for high-quality heating of 20 square meters of room . The radiator also performs very well when applying pressure testing, which (in some cases) can be increased to 18 bar without any damage to the integrity of the structure. The temperature of the coolant in the pipes can reach up to 150 degrees Celsius, leveling out all possible manifestations of jumps in the main parameters, especially when working in an individual heating system.
According to consumers, another important advantage of the STI Nova is its appearance. Manufacturers managed to create a rather nice design that can fit into any interior. In addition, these radiators are very unpretentious in maintenance and easy to install, even despite their rather heavy weight.
Article outline
Buying a heating radiator (HR) is not a trivial task. There are many models, they cost differently, and it is not always clear which of those presented on store shelves meets our requirements. Therefore, we will save your time and tell you what to consider when choosing. We present to your attention rating of the 20 best heating radiators for apartments and private houses. Choose any of them - you won't go wrong!
For a private house or apartment?
There are dozens and hundreds of companies specializing in the production of radioactive materials. The competition is crazy. Marketers are coming up with new arguments in favor of their products. This makes the choice of characteristics richer, and making a purchase more difficult for the average buyer. Let's start with the simplest thing.
If you need a device for a private house or apartment with an individual heating system, then choose by power and design. Those. We saw a model we liked in appearance, selected it based on power/size – and that’s it. For an apartment in a multi-storey building, where the coolant is supplied through the pipes of a centralized heating system, you also need to take into account the operating pressure set by the manufacturer. It should not be lower than 10-12 atmospheres. Otherwise, the structure will tear when water is supplied.
Now let’s look at the types of heating radiators, traditionally presenting the data in the form of a “tiny” table.

| Gasket material | Silicone | Withstands high temperatures, effectively compensating for the expansion of metal structures. Ideal for low pressure heating systems, for example in private homes. |
| Paronitis | Paronite is pressed rubber mixed with asbestos and other components. Durable, withstands high temperatures. It is most often used in centralized heating systems. | |
| Fluoroplastic | A product made of heat-resistant polymer that can be installed without lubrication. Withstands exposure to any type of coolant. | |
| Cardboard | Impregnated with oil paint, special cardboard successfully copes with its function in aluminum and bimetallic RO installed in private homes. | |
| Coolant | Water | We are not talking about plain water, but about specially prepared water. This is exactly what circulates in the centralized heating system. It limits the content of hardness salts (due to which salt deposits form in the pipes - scale) and oxygen (due to which the material corrodes and breaks down). Water requirements in the EU and the Russian Federation are different, so when purchasing a foreign-made heating radiator, it is recommended to take into account the chemical composition of the water in your heating system. If desired, you can find it out at the Housing Office. |
| Antifreeze | Antifreezes or “anti-freeze” agents are used for systems with an individual heating circuit. They are needed if there is a risk of the coolant freezing due to the boiler being turned off. As you know, coolant is always in the system. If, for example, in winter the water in the system freezes, then due to expansion it will rupture the pipes, radiator, etc. Antifreeze does not freeze at average sub-zero temperatures. Ethylene glycol, propylene glycol, and alcohol solutions can serve as such coolants. | |
| Installation location | Stationary | Traditional heating radiators installed in most apartments. Mounting to the wall is carried out using special pin or corner brackets |
| Floor-standing | The same as stationary devices, only they are installed on special legs. | |
| Operating pressure* | up to 10 atm. | Such values are predominantly typical for panel-type devices. |
| up to 20 atm. and higher | For tubular and sectional RO. | |
| Center distance | 350, 400, 500, 600, 700 mm | The distance between the axes of horizontal collectors, along which a device is selected for connection to the existing pipe distribution. |
| Connection method | Lateral one-sided. (subtype of side connection) | The most common and effective solution in terms of using the capabilities of RO. Connection from the side: from above - to the pipe supplying coolant, from below - to the outlet. |
| Diagonal (subtype of lateral connection) | Most often used when connecting long devices (from 2 m and above), which allows the coolant to be evenly distributed throughout the entire volume of the structure. Inlet from above, outlet from the lower opposite side. | |
| Saddle (subtype of side connection) | For sectional ROs when it is impossible to use other methods. Inlet and outlet from the bottom on opposite sides of the device. In this case, the heat exchanger power may drop by 10-20%. | |
| Lower | For connecting panel RO with hidden pipe routing under the floor. Inlet and outlet from below at a short distance. The efficiency of the radiator is lower than with lateral and diagonal connections. | |
| Thermal power** | values in a wide range | Characterizes the radiator’s ability to transfer a certain amount of heat from the coolant to the room per hour of operation. It depends not only on the size and design of the RO, but also on the temperature of the coolant, as well as the air in the room. |
| Dimensions | On average: height from 260 to 800 mm, width from 270 to 1800 mm, depth from 50 to 100 mm | Directly affect the thermal power of the device, because The volume of coolant circulating in the device depends on this. |
* Before choosing a device, you need to check with the housing office about the maximum pressure in the heating system. Remember that all radiators except aluminum ones are suitable for a centralized heating system!
** We are often asked about how to choose the right heating radiator based on power. To make life easier for you and yourself, we have developed a convenient calculator. Enjoy it for your health!
For those who want to estimate the thermal power on their own, you can use the following method. We determine the required values per unit area of the room: 100 W/m2 – one window and one external wall; 120 W/m2 – one window and two external walls (corner room); 130 W/m2 – two windows and two external walls (corner room). For example, there is a corner room of 20 m2 with two windows. Then the approximate power of the RO will be: 20 × 130 = 2600 W. Let's make an allowance for the fact that the nameplate characteristics of radiators are tied to the ideal operating conditions of the device - 10% is quite enough. In total, we get the required thermal power: 2600 × 1.1 = 2860 W.
All that remains is to decide on the desired model, which you can find among the 20 devices we have selected.

In addition to the heat exchanger itself, do not forget about the control valves (thermal head) and the Mayevsky tap (if not included), which must be purchased separately. In some cases, the same applies to installation kits. Single-pipe heating systems will require a bypass.
We offer you a small rating that contains the best models of heating radiators. To make it easier to compare, we tried to select devices with the same number of sections - most often there will be 6 of them. This border solution is most in demand for standard apartments. All prices are for comparison purposes only.
5 bimetallic radiators
1. Global STYLE PLUS 500, 6 sections – from 4600 rub.
STYLE PLUS 500 model of the famous Italian manufacturer Global. A special feature of STYLE PLUS 500 is an increased safety margin - the product can withstand pressure up to 35 atmospheres - as well as an increased diameter of the vertical channels connecting horizontal collectors. To seal the connections of the sections, special silicone gaskets are used, designed for contact only with treated water - other types of coolants are not allowed. This bimetallic product is designed in such a way that air pockets do not form inside, preventing the correct operation of the device. Warranty – 10 years.
2. RIFAR ALP-500, bimetal, 6 sections – from 3800 rub.
In 2002, the Russian company Rifar quickly burst into the production of heating radiators for private houses and apartments, and since then has achieved considerable success. The main specialization of RIFAR is the development and production of bimetallic and aluminum devices. In the RIFAR ALP-500 bimetallic radiator model, high heat transfer is achieved due to the developed lateral surface of the section. Therefore, the design turned out to be very slender - only 75 mm thick! There are models on sale with a number of sections from 4 to 14, connected through silicone gaskets that provide uncompromising tightness. RO can be made in any of the colors of the RAL 9016 palette. However, it must be taken into account that the coolant for such a device should only be specially prepared water - “anti-freeze” agents used in heating systems of private houses will not be suitable here. 10 year warranty.

3. SIRA RS 500, bimetal, 6 sections – from 5100 rub.
The Sira brand produces high-quality Italian ROs, including the model we are interested in - RS 500. Reliable, stylish and efficient - this is how this product can be characterized. The company has been around for more than half a century, so only proven solutions are used: a solid steel frame with an outer layer of aluminum, high-quality painting. It differs from other solutions in the absence of sharp corners. The warranty is 20 years. However, you need to take into account that the installation kit is non-standard and is not available for sale everywhere, so it is better to buy it first.
4. Rifar Monolit 500, bimetal, 6 sections – from 5600 rub.
It is no coincidence that the Monolit 500 model from the previously mentioned manufacturer Rifar was included in our rating. This is all due to the fact that the Russian company has really succeeded in developing innovative heating solutions. The product fully lives up to its name - it is monolithic, the sections are conventional, because they are welded together, forming a solid structure. Thus, the possibility of coolant leakage is reduced to zero. This RO can withstand pressure up to 100 atmospheres! Plus, there are practically no restrictions on the coolant used. The manufacturer's warranty is 25 years.
5. Royal Thermo PianoForte 500, bimetal, 6 sections – from 9,000 rub.

5 cast iron radiators
16. Viadrus Styl, cast iron, 6 sections – from 9,000 rubles.
Positioned by the Czech manufacturer as designer, but in reality almost classic cast-iron radiators also made it into our small rating. Unlike its counterparts, the capacity of each section of such a RO is small, which means that the amount of heat received can be quickly varied. The disadvantage of this approach is low power. Regarding the advantages, one cannot fail to note the possibility of side and bottom connections. The product already has a temperature-controlled valve built in for these purposes. Various color solutions are possible. Manufacturer's warranty – 10 years.
17. MZOO MS-140M-05, cast iron, 7 sections – from 3500 rub.

When you are going to buy heating radiators, you need to prepare in advance. The desire to purchase devices is not enough. You need to study the technical characteristics and parameters of radiators to find out which heating radiators are best - specifically for your heating system.
You can compare completely identical battery models in appearance, but in terms of heat transfer and power, they can differ noticeably. Here everything will depend on the material of the radiator and its design features, the internal capacity of the batteries, and the method of connecting them. That is why, when you choose which heating batteries are best, you need to prepare and have some knowledge.
What are the requirements for installing radiators?
If you believe standard calculations, the consumption is 90-125 W per 1 sq.m of room that is heated. In this case, the presence in the room of a window, a door, a ceiling height of no more than 3 meters, and a coolant temperature of 70 degrees Celsius are also taken into account.
If such standards are violated, for example, the ceiling height is higher, then the power of the radiators should be increased by the same amount. And if you have double-glazed windows, then they have low heat transfer; accordingly, as reviews show, the power can be reduced by 10 percent.
If the coolant temperature drops, this will require increasing the power of the batteries, or the number of sections can be increased. Every time the temperature drops by 10 degrees, this is compensated by increasing power by 15-18%.
When calculations are made, no matter what the best heating radiators are, it is imperative to take into account the design features of your heating system. And if the coolant is supplied through the lower hole, and the return flow is through the upper, then in this case each radiator will not provide up to 10 percent of its power. If the coolant is supplied only from one side, then installing more than 10 sections will be pointless - after all, the last sections will heat rather weakly.
Comparison of heating batteries
First of all, we note that answering the question of which heating batteries are better is quite difficult without having special knowledge. Note the panel steel radiators. Such heating devices are highly efficient - their operating pressure is 9 atmospheres, they can withstand 13 atmospheres of pressure testing. As the rating of heating radiators shows, they are in great demand when an individual heating system is installed and when multi-storey buildings have their own heating point.
Such high-quality heating radiators are made from steel sheets with special recesses for the passage of coolant, and in order to increase the heat transfer of the devices, protruding ribs are welded to the back side, which will further increase the convection air flow. Radiators are made of low-carbon steel, which has increased corrosion resistance. They are coated with powder enamel.
The next type we will consider is cast iron radiators. Of course, this option will not answer the question of what are the best heating radiators.
Cast iron batteries are a classic that Soviet consumers previously used for lack of anything else.
These are really high-quality products, the main advantage of which is cast iron. This material has excellent thermal conductivity and is resistant to any coolant. The proportion of radiation flux includes 70% heat and 30% convective - this will warm the lower and upper zones of the room. It is worth noting that the service life of a cast iron radiator can be up to 50 years. Today, such radiators can be bought relatively cheaply; there are different models on the market, as can be seen in the photo.
Cast iron radiators
At a superficial comparison, aluminum radiators will seem lighter and more elegant to you. But then you will find out that these best heating batteries also have improved heat dissipation. Such radiators are produced by casting or extrusion. Each section has collectors, as well as a connecting vertical channel, ribs to accelerate air flow and remove heat from the plane, which is why the heat in the room will be optimally distributed.
Such radiators are assembled with steel nipples, and special gaskets made of waterproof material are placed between the sections. There are fins on the front surface, this forms a continuous surface, as well as air outlet windows on top. The thermal power of such radiators must be selected by selecting the required number of sections, as well as their height. You can simply assemble a radiator with the desired height and length to fit well into the architectural features of your room.
As for the disadvantages of this type of battery, these are high requirements for the chemical parameters of water. In addition, it contains heat exchangers, brass and copper fittings, connecting pipes made of steel - all this increases the corrosion process. And the more copper there is, the stronger this process will be. To mitigate this drawback, manufacturers use alloys that will protect the batteries from the inside.
As experts note, bimetallic radiators are the most efficient heating batteries.
Steel channels that conduct coolant will ensure the strength of the entire structure. They are also covered with aluminum fins, so water only comes into contact with the metal. There are several different versions of such batteries. They can be made by covering a steel frame with aluminum - this way, water will only come into contact with the steel. Vertical channels can also be reinforced with steel so that their thickness can withstand high pressure.
The best bimetallic heating batteries can withstand high pressure and long-term load, they are resistant to water hammer and have a high level of heat transfer. The working pressure is 35 atmospheres, and the pressure test is almost 52. And due to the fact that the capacity of the bimetallic sections will be less than that of aluminum, this has a positive effect on thermal inertia. As the test shows, heating radiators are the most efficient and reliable in multi-storey buildings. After assembly, these best heating radiators are painted with powder enamel, and to cure they are heated and kept at 180 degrees Celsius. With a maximum coolant temperature of 110 degrees, this will be enough.
We suggest studying a comparison of heating radiators; the table (Table 1) will show all the strongest and weakest points of different types of radiators.
After all, the question of which heating radiators are better may be relevant for quite a long time, and only a specialist who is familiar with your heating system can answer it fully correctly.
More details about the choice of bimetallic heating radiators in the material -
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:
- System operating pressure. 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.
One of the main components of a home heating system is a radiator - a heating battery, as we used to call it. Let's consider radiators for heating - which ones are better for a private home, what are they made of?
Living in a private home has many advantages; at the same time, a lot of worries and efforts fall on our shoulders; we strive to ensure that everything is equipped competently and efficiently. An autonomous heating system in a private house is one of the main aspects responsible for comfortable living. You will not be dependent on a centralized system; you will always be able to heat your home, regardless of the heating schedule (as happens in urban residential buildings). You can calculate and install your own heating system according to your wishes and, of course, each of us strives to ensure that everything in this matter is done reliably, for many years to come.
The correct choice of equipment is important both for the budget and for subsequent comfortable operation. Today the construction market offers a wide range of modern heating equipment. When choosing radiators, you should consider options with a favorable price ratio and maximum heat transfer rate. Judging objectively, any batteries can be suitable for a home heating system, but there are still certain nuances.
Heating radiators - which ones are better?
What are modern batteries like? If we consider the so-called steel options, then there are panel or tubular models. Despite the fact that they are considered the most budget-friendly, they are characterized by good heat transfer and relative compactness. Panel models consist of two metal plates connected to each other by welding. Due to their area, such radiators are able to provide a lot of heat.
Panel version, photo:
Tubular options will cost you a little more than their panel counterparts; they have a quite laconic appearance, somewhat reminiscent of ancient cast-iron batteries. They can come in a variety of designs, shapes and sizes.
Tubular batteries, photo: 
Some models of steel radiators have an internal polymer coating that prevents corrosion processes.
Advantages of steel structures:
- reasonable price along with high efficiency;
- do not oxidize due to poor quality water;
- long service life
- light weight
- convenient sizes.
The disadvantages include:
- rough appearance (panel version);
- require flushing every 3-4 years (to avoid slagging of the system);
- need to be constantly filled with water (to avoid activation of corrosion processes).
Aluminum radiators
Due to their light weight, they can be mounted even on thin walls and partitions. They have an aesthetically pleasing modern design and are characterized by high heat transfer. Disadvantages - short service life (15-17 years), susceptibility to corrosion, leaks can form at the joints of sections. According to the specifics of connecting sections, aluminum batteries can be assembled, solid and combined. One-piece models are more reliable, they do not have joints through which water can leak over time. The assembled radiators allow you to replace sections that have become unusable. Combined models have the qualities of the first two analogues.
Aluminum batteries, photo: 
Bimetallic heating radiators
They are considered the most “advanced” and improved. These batteries combine the qualities of different types of metal - heat transfer from aluminum, resistance to rust (inside they are made of copper or high quality steel). The bimetallic radiator has a layer of anti-corrosion coating both inside and outside (in more expensive models). The declared service life of such batteries is 40 years. They have a higher price compared to all other types of radiators, but the monetary costs are offset by quality and high performance.
Bimetallic version, photo: 
Cast iron radiators
The most durable, reliable and time-tested. The first cast iron batteries appeared more than 100 years ago. Their appearance is known to everyone, despite the fact that the service life of this radiator is 50 years, they can still be found in many homes. Such batteries cool down slowly and retain heat longer (compared to, for example, an aluminum counterpart) - this factor allows you to reduce gas costs.
Examples of modern cast iron batteries, photos: 
A cast iron heating radiator is highly resistant to corrosion processes and has thick walls. Despite the fact that the internal volume of the sections is quite large and requires a large amount of water to fill, this feature makes it possible to provide heat to a large area of the room. Such batteries are heavy and require appropriate powerful brackets for mounting. Over the years, their appearance has not changed much, but today you can find improved versions of modern cast iron radiators on sale. The outer surface of such structures has an improved design that is suitable for a certain interior style (classic, retro).
In terms of price, these radiators are more expensive than aluminum models, but cheaper than bimetallic ones.
What heating radiators are good?
After conducting a small comparative analysis of the proposed models for a private home, we can draw conclusions:
- If you want a reliable, economical option, then choose a high-quality aluminum battery from a well-established manufacturer. They are aesthetically pleasing, lightweight, and will work perfectly in a home autonomous heating system.
- If the issue of price does not bother you, then choose sectional bimetallic radiators - they are good in all aspects.
- Reliable, solid cast iron options will keep your home warm for a long time, and they are also very convenient for drying things during the cold season.
To the question - which heating radiators are best for a private home, the answer will be this: in each individual case you need to calculate your capabilities and take into account the requirements of your individual heating system. It is necessary not only to calculate the correct number of radiators, but also to provide high-quality thermal insulation of the entire house. If your home is poorly insulated, not a single radiator will help in the fight against the cold.
