Which heating radiators are best for an apartment: a detailed analysis of the modern market. How to choose heating radiators for an apartment or house? The best and high-quality heating batteries for the apartment

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.

Table of advantages and disadvantages of different types of radiators.

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 the company “Thermal” has 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 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.

When organizing a major renovation of a house or apartment, the list of activities of which includes the replacement or modernization of the heating system, the owner will inevitably face the problem of which heating radiators are best to choose in order to increase the comfort of living and at the same time not lose with the interior design.

Previously, such a question was usually not raised in principle - in addition to cast iron batteries of a single model, inefficient, poorly made steel convectors were only sometimes installed in new houses. Today the situation is different - radiators can differ significantly in material of manufacture, characteristics, and external design. Naturally, you want to install in your apartment the best of those that the budget allocated for renovation allows.

However, when choosing these devices, you need to take into account that not all of them may be suitable for the existing heating system. Having different performance characteristics designed for a certain load and coolant, batteries can either disappoint the buyer with their low efficiency, or even simply not fit the technical parameters.

In addition, in order to achieve proper heating efficiency, it is necessary to correctly calculate and install the required number of sections in the radiators. Just do it V in all conditions and making sure to adhere to installation rules, you can get the desired result.

Currently, the most common types of heating batteries are: The following types of radiators are produced:

— steel, panel and tubular;

— cast iron, having both modern and retro design;

— aluminum and aluminum anodized;

- bimetallic.

To make the right choice, you need to understand in more detail the characteristics, advantages and disadvantages of each type. To begin with, here are a few “dry” numbers, which, nevertheless, can already give an initial idea. Some parameters of various types of batteries are in the table:

Abbreviations in the table:

TS– tubular steel;

Chg– cast iron;

Al– regular aluminum;

AA– aluminum anodized;

BM– bimetallic.

Well, now - about each of the types in more detail.

Steel radiators

They may differ both in their design and in their design solutions. They can be made in the form of panels or a certain number of vertical pipes interconnected into one common battery.

Panel steel radiators

Each panel of such a radiator is made of two metal sheets, which are given the desired shape by stamping and joined by welding. Then, in most of the models, the panels are equipped with convector heat exchangers, which contribute to the rapid heating of the air and the creation of a thermal upward flow. After combining all the elements into a single structure, it is painted using a special technology.

In order for this type of radiator to serve for a long time, the coloring must be uniform - you need to pay special attention to this parameter when purchasing.

Panel radiators are designed for a coolant temperature of 85 ÷ 95 degrees, and for standard operating pressure in a central heating system (up to 10 atmospheres).

Similar batteries have your own classification, which is predetermined by the number of panels and the presence of convector plate heat exchangers between them. Each type is expressed by a specific two-digit number:

• Type 10 consists of only one panel;
• Type 11 is one panel equipped with one convector;
• 21 type - has two panels and one convector located between them;
• Type 22 - consists of two panels and two convectors;
• Type 33 - has three convectors, which are located between three panels.

There may be significant differences between models And by overall dimensions. It is clear that the more panels, the thicker the assembled structure itself, usually from 50 to 155 mm. The length of such a battery can vary from 400 to 3000 mm, and height - usually, ranging from 200 to 900 mm.

Panel batteries are produced with side and bottom connections - the choice for this parameter is made depending on the passage of the heating system pipes and the preferences of the owners.

The advantages of panel batteries include the following:

• Easy to install. The battery has a one-piece design, so it does not need to be assembled from several elements. The panel is hung on brackets fixed to the wall, and the pipes are connected to the heating circuit pipes.
• Due to the small mass of the steel sheet, the panel warms up almost immediately after starting the heating. This promotes good heat transfer both from the surface directed into the room and in the plate heat exchanger, which makes it possible to obtain the desired air temperature in the room quickly enough.
• Compact size and neat appearance allow the panels to fit into any interior.
• The operation of panel batteries in an autonomous heating system allows you to save on fuel, since a relatively small amount of coolant is used to fill the circuit.

The negative features of the panels include the following factors:

• Metal panels do not have an anti-corrosion coating on their inner surface, which is in direct contact with the coolant, which can lead to fairly rapid rusting, leaks, and failure. This is especially typical for central systems, where the coolant is drained in the summer, opening up “wide opportunities” for corrosion processes. And the quality of the coolant also does not always contribute to the duration of trouble-free operation of the devices.
• If batteries are installed in a central heating system, then it will not be possible to avoid water hammer, which the panels may not withstand. Therefore, it will also be necessary to install a reducer that equalizes the pressure and takes the blow.

Tubular batteries

Tubular steel batteries consist of stacked sections that are welded together. The efficiency of this design will be at the proper level if the required number of sections are installed in the battery, with a total thermal power corresponding to the area of ​​the room.

Tubular radiators can have a very wide variety of different design solutions, and this is one of the criteria that directly influences the choice of this particular type of battery. In addition, tubular batteries can be equipped with a special bracket for drying towels, which is very convenient, for example, for the kitchen, or a top panel that can serve as a seat or shelf for drying shoes.

They are produced in different sizes, the height varies from 200 to 2000 mm, and the thickness, as a rule, from 100 to 250 mm. The ordered length can be any, depending on the heating needs.

These elements of the heating system can withstand pressure from 8 to 15 atmospheres. To avoid damage to batteries due to water hammer, if they are installed in a central heating system, they, like panel ones, will require the installation of a gearbox.

The wall thickness of steel tubular radiators is only 1 ÷ 1.5 mm, so they warm up very quickly and release heat into the room. But this same factor can also be attributed to design flaws, since thin steel is easily susceptible to mechanical damage.

Unlike the panel type, the tubes of these batteries are internally coated with polymer protective films, which protect them from exposure to the aggressive coolant environment, and as a result, from the occurrence of corrosion, which significantly extends their service life.

The advantages of tubular steel batteries include a variety of design solutions in shape and color, the provision of radiators with additional elements, and an original, neat appearance.

This type of battery has only two serious disadvantages, but they can have a much more significant impact on the home heating system than the already mentioned advantages:

• Low heat transfer, which will lead to high energy costs. The batteries heat up quickly, but also cool down quickly, so the boiler will turn off for a very short period of time. The absence of an additional heat exchanger, other than the surface of the pipes themselves, makes the area of ​​active heat transfer very small. This ultimately suggests that tubular batteries are unprofitable to install in an autonomous heating system.
• At the same time, welded connecting seams can be considered a weak point of such batteries - there have been cases of leaks appearing on them after water hammer. The conclusion is quite the opposite - tubular batteries without a gearbox can only be installed in a system with autonomous heating.

In a word, there are a lot of contradictions, and you need to think very carefully before purchasing such heating batteries.

Cast iron radiators

Although today a large number of batteries are produced from modern materials, cast iron elements of the heating system have not been forgotten. They can be found in stores in a transformed form, decorated for modern interiors or for strict “classics”. In some cases, such radiators even play the role of a decorative element and are able to set the tone for the entire design of the room.

In addition, modern cast iron batteries do not require periodic painting, as was the case with old “Soviet” models. They go on sale with a treated and painted surface, which only needs to be wiped or dusted occasionally.

Modern radiators can have different sizes, so they can be selected to suit any size room area. In addition, if old batteries had to be hung on brackets driven into the walls, today you can purchase options that have massive legs on which they are installed and secured to the floor in a specific place for them.

Unlike all other types of batteries, cast iron ones have an important advantage - they will function equally effectively in both autonomous and central heating systems. The main thing is that all connections of sections and pipes are made correctly and reliably - then the cast iron elements will not be afraid of either water hammer or corrosion.

Despite the emergence of new battery options, cast iron continue to be popular due to their excellent heat capacity- ability to retain heat for a long time. They have thick and massive walls that take a long time to warm up, but, having gained temperature and warmed up, when the heat flow along the circuit is turned off, they remain hot for a much longer period than radiators made from other materials. This is due to the properties of cast iron - it is not without reason that it is widely used for the manufacture of heating stoves and or individual components for them.

In specialized stores you can find both domestic and imported versions of cast iron radiators. Countries such as Germany and Turkey, Spain and England, the Czech Republic and Italy are presenting their products - in many respects they compare favorably with those manufactured at domestic enterprises.

• Imported radiators have high-quality smooth or decorated with relief casting surfaces.
• An important functional feature is the high thermal output, even with small dimensions. For comparison, you can take the volume of a traditional domestic battery, which is 1.3 liters, while a Czech-made radiator has a volume of only 0.8 liters, with the same heat transfer. Thus, the foreign version will be more compact and will save a decent amount on coolant and on boiler operation.
• In addition, unlike domestic ones, imported batteries have a perfectly smooth internal surface, which prevents the formation of scale on the walls and significantly reduces the hydraulic resistance to coolant circulation.
• Since any cast iron radiators are resistant to corrosion, they can be used in open heating systems, where a large amount of dissolved air enters the coolant.
• All cast iron batteries have fairly thick walls, which increases their resistance to possible abrasive wear.
• Unlike domestic ones, imported radiators are supplied to stores already painted and do not require periodic renewal of the coating, which will save not only money, but also the time of homeowners.

However, all foreign-made products have a price much higher than the cost of domestic batteries.

The disadvantages of all cast iron batteries include their heavy weight, so they can be hung on all walls or partitions. And the process of mounting it on the wall is somewhat more complicated than with other radiators.

Aluminum batteries

Aluminum batteries are only suitable for installation in an autonomous heating system, since they are quite demanding on the quality of the coolant. This type of radiator is quite popular among owners of private houses due to its affordable price, good performance and modern appearance.

Manufacturers set in the passport the minimum service life for aluminum batteries at 10 ÷ 25 years, but they may well last for a longer time. The duration of their “life” will directly depend on the quality of the coolant, the correct installation and operation of the heating device.

Prices for aluminum radiators

Sectional aluminum radiator

This one is designed for a pressure in the system of up to 15 atmospheres, a coolant temperature of 90 ÷ 100 degrees, and the heat transfer of the section can reach up to 200 ÷ 210 W. At the same time, the capacity of each radiator section is only 450 ml, and the weight is 1.0 ÷ 1.5 kg. The individual sections are fastened together into a single battery using a threaded axial connection.

The standard distances between the upper and lower axles are 200, 350 or 500 mm, but it happens that non-standard options are also manufactured with an interaxle distance of 800 or even more millimeters.

Aluminum radiators, just like all other heating devices, have their advantages and disadvantages.

TO benefits Their qualities include the following:

— high level of heat transfer;

- light weight;

— relative ease of installation;

— convenient and wide range of sizes;

— neat, aesthetic appearance;

— as a rule, it is equipped with a thermostat, which allows you to set the desired temperature.

From shortcomings The following are worth mentioning:

— possible risk of gas formation, which can provoke “ airing" and blockage of the heating circuit;

— the possibility of leakage at the connections of individual sections;

— the main concentration of heat is on the fins of the elements.

— susceptibility of some types of aluminum radiators to corrosion processes.

Some problems that can occur with aluminum batteries can be avoided. For example, in order for possible gas formation to paralyze the operation of the system, it is necessary to cut into a common autonomous circuit or install an air vent on each battery. And in the case of an autonomous system, it is generally better to use one that is well adapted to aluminum (this is described in detail in the corresponding publication of the portal).

Aluminum battery sections are made from aluminum alloy using silicon additives, but different models may also differ in the way they are made manufacturing - casting and extrusion.

• The first method involves manufacturing each section separately by pouring the alloy into special molds under high pressure. The silicon present in the alloy gives special strength to the walls of the radiators, and the manufacturing method fully guarantees the tightness of the container.

Batteries made by this method are able to withstand operating pressure in the system reaching up to 16 atmospheres. During testing, the coolant is supplied to this type of battery under a pressure of 25 atmospheres, that is, when characterizing its products, the manufacturer gives a safety margin of one and a half.

Using this technology, sections of various shapes are made, but traditional ones still remain those that have a flat, smooth outer surface - it is optimal for better heat transfer.

• Another method of making sections is the extrusion method. Using this technology, the melt is pressed through forming nozzles - the desired profile of the workpiece is obtained. This is followed by cutting the profile into individual parts.

Then the finished sections are assembled into a single structure. Batteries made in this way have a lower cost, but during operation they cannot be increased or made smaller - the design is non-removable. The quality of such radiators is also lower, since the joints of the sections (with seals or even with special glue) under unfavorable circumstances may leak and cannot be repaired.

Aluminum batteries with anodic oxidation

There is another type of aluminum batteries. They are made from metal that has a high degree of purification, and also undergo a stage of anodic oxidation - which is why the term “anodized aluminum” is often used. With this special treatment, aluminum slightly changes its structure, and if conventional aluminum radiators are susceptible to oxygen corrosion, then anodized sections withstand this influence with dignity. In such structures, batteries are assembled using couplings that are secured to the outside of the sections.

Anodized sections for radiators are made by casting, and in appearance they are almost no different from conventional aluminum batteries. Therefore, when purchasing them in a store, you must carefully study the passport, which should be attached to such products.

The internal surfaces of this type of radiator are absolutely smooth, so there are no obstacles to the circulation of coolant. Their upper limit of operating pressure is much higher than that of conventional aluminum ones, and ranges from 45 to 75 atmospheres.

Naturally, due to their outstanding technical characteristics, the cost is also significantly higher. But still, in order for aluminum batteries to last as long as possible, it is worth choosing radiators of this particular type.

Bimetallic batteries

In terms of reliability, bimetallic radiators are, perhaps, second only to cast iron ones. They are produced according to a combined principle, from two metal alloys - the inner part is made of a stainless steel alloy, and the outer part is made of aluminum coated with a layer of enamel.

Bimetallic batteries also consist of sections that are connected via a threaded connection. At the same time, their exceptional reliability is based on the fact that the outer aluminum casing does not come into any contact with the coolant, but serves only as an effective heat exchanger (thanks to the highest thermal conductivity of this metal) and somewhat of a decorative element. And water or antifreeze circulates through channels made of a steel alloy, which is more resistant to pressure loads and oxygen corrosion. Thanks to this, such batteries can easily withstand pressure surges of up to 35 ÷ 40 atmospheres.

These qualities of bimetallic batteries make it possible to install them, without any restrictions, both in the central heating system of high-rise buildings and in the autonomous heating system of a private house. The only thing is that in the second case it would be desirable for them to create the necessary pressure, otherwise they will not function at full strength, losing a number of their advantages. This means that natural circulation will not work here, and it is necessary to install a circulation pump in an autonomous system.

Bimetallic batteries are quite expensive - their price is, in any case, much higher than that of steel or conventional aluminum ones, but this is fully justified by their high reliability and long service life. In fact, high cost can be called the only drawback, while they have much more advantages:

• The high thermal conductivity of the outer aluminum “shell” makes it possible to quickly heat the room.
• The corrosion resistance already mentioned above.
• Compactness and aesthetic appearance, thanks to which the radiators will fit perfectly into any interior style.
• Bimetallic batteries do not require special care or periodic painting, as they are covered with a two-layer hardened polymer coating.
• Ability to withstand high temperatures and increased operating pressure, thanks to the internal steel casing.
• Relatively light weight, easy installation, which can be carried out without the help of specialists.

The appearance of bimetallic radiator options is somewhat similar to aluminum batteries, but the difference in price is quite significant. When purchasing, sometimes it is even impossible to distinguish between two adjacent types of radiators, so it is better to purchase them in specialized stores or from trusted suppliers. Be sure to require technical documentation.

Prices for popular heating radiators

When choosing, you should not save, because by buying cheap, low-quality products, you can doom yourself to another, completely unplanned and unwanted repair in two or three years. Installation by the owner of radiators that are unsuitable for the existing heating system can ruin not only the flooring in his own apartment, but also lead to serious problems with flooded neighbors below. So, saving on little things can lead to significant costs later.

Therefore, when purchasing any product, it is necessary to study not only the passport with the specified technical characteristics, but also the certification of the product with the manufacturer’s warranty obligations. This is important to do in order to avoid buying fakes, which are very similar to the “brand” sample in appearance, but still remain of low quality.

To “consolidate the material”, it is suggested to watch a video lesson that will help answer the question: “Which heating radiators are better?”

And one moment. It is important not only to decide on the type of radiators - the total thermal power must correspond to the parameters of the room where they are installed. To carry out such calculations, we suggest using a special calculator located below.

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 well in the room.

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 rooms 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 kind of 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 aluminum device 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.

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 outside of the radiators are covered with durable paint 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 to 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.

Many people are forced to live in difficult climatic conditions. Not everyone can move to more suitable regions, so most of the time has to be spent in well-heated rooms. This suggests that heating systems should be as efficient as possible, and special devices for them should be aesthetically pleasing! So which heating batteries are better for an apartment, what are their prices? You will find answers to these questions in our article.

What to look for when choosing radiators?

Modern heating devices should be selected with extreme care, as they must serve their owners for a long time and reliably. The main selection criteria are:

System type. Today, 4 types of radiators are especially popular, each of which has its own advantages and disadvantages. Cast iron models are characterized by low cost, excellent thermal conductivity, durability and the ability to retain heat even after the heating is turned off. Their disadvantages include slow heating, the need for frequent maintenance, fragility, consumption of large amounts of water and poor tolerance to water hammer. Aluminum systems have high heat transfer, compactness, reasonable cost and light weight, but they are subject to corrosion. Steel radiators heat up quickly and are liked by customers for their low inertia and maximum heat transfer, but the most significant disadvantage of this type is the formation of rust. Bimetallic models are very demanding on water quality, but at the same time they are light in weight and resistant to high pressure.

Price. Water heating devices are considered the cheapest, so when purchasing them you can save a good amount of money. Foreign goods, of course, will cost more than domestic ones, but some of them will last much longer. Cast iron and aluminum radiators cost on average 350 rubles per section, bimetallic ones - about 600 rubles per section, and steel ones in a complete set will cost 2-12 thousand rubles.

Heat dissipation. Non-sectional radiators (steel) have a total heat output of 1200 to 1600 W. As for this criterion for one section, in cast iron it is 100-160 W, in aluminum - 82-212 W, and in bimetallic - 150-180 W.
