Which copper radiators are better. Which heating radiators are best for an apartment and a private house. Comparative characteristics of heating radiators

When you are going to buy heating radiators, you need to prepare in advance. Just wanting to buy appliances is not enough. It is necessary to study the technical characteristics and parameters of radiators in order to find out which heating radiators are better for your heating system.

You can compare completely identical battery models in appearance, but in terms of heat transfer, power - they can differ markedly. Here everything will depend on the material of manufacture of the radiator and its design features, the internal capacity of the batteries, the way they are connected. That is why, when you choose which heating batteries are better, you need to prepare and have some knowledge.

What are the requirements for installing radiators?

If you believe the standard calculations, then the consumption is 90-125 W per 1 sq. M of the room that is heated. In this case, the presence of a window, a door in the room, 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 height of the ceilings is greater, then the power of the radiators should be increased by the same amount. And if you have windows with double-glazed windows, then they have low heat transfer, respectively, as reviews show, the power can be reduced by 10 percent.

If the coolant temperature drops, then this will require an increase in battery power, or you can increase the number of sections. Every time the temperature drops by 10 degrees, this is compensated by an increase in power by 15-18%.

When calculations are carried out, 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 heat carrier is supplied through the lower hole, and the return stroke is through the upper one, then in this case each radiator will not add up to 10 percent of its power. If the coolant is supplied only from one side, then it will be pointless to install more than 10 sections - after all, the last sections will heat quite weakly.

Comparison of heating batteries

First of all, we note that it is quite difficult to answer the question of which heating batteries are better without special knowledge. Note the panel steel radiators. Such heaters are highly efficient - their working pressure is 9 atmospheres, they are able to 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 of steel sheets with special recesses for the passage of the coolant, and in order to increase the heat transfer of the devices, protruding ribs are welded on the reverse side, which will further increase the convection air flow. Radiators are made of low carbon steel, which has increased corrosion resistance. They are covered with powder enamel.

The next type we will look at is cast iron radiators. Of course, this option will not be the answer to the question of what are the best heating radiators.

Cast iron batteries are a classic that Soviet consumers used in the past 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, it is resistant to any coolant. The share of the radiant flow 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. To date, such radiators can be bought relatively cheaply, there are different models on the market, as can be seen in the photo.

Cast iron radiators

In a superficial comparison, aluminum radiators will seem lighter, more elegant. But then you will find out what best batteries heating also have improved heat dissipation. Such radiators are produced by casting or extrusion. Each section has collectors, as well as a connecting vertical channel, fins to accelerate the flow of air and remove heat from the plane, which is why the heat in the room will be distributed in an optimal way.

Such radiators are assembled with steel nipples, 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 vent windows on top. It is necessary to select the thermal power of such radiators by a set of the required number of sections, as well as their height. You can simply assemble a radiator with the right height and length to fit it well into architectural features your premises.

As for the disadvantages of this type of batteries, these are high requirements for the chemical parameters of water. In addition, it includes heat exchangers, brass and copper fittings, connecting pipes from steel - all this increases the corrosion process. And the more copper there is, the stronger this process will be. To offset this shortcoming, manufacturers use alloys that will protect batteries from the inside.

According to experts, bimetallic radiators are the most efficient heating batteries.

Steel channels that conduct the coolant will ensure the strength of the entire structure. They are also covered with aluminum fins, so water comes into contact only with metal. There are several different options performance of such batteries. They can be made by coating the steel frame with aluminum - so the water will only come into contact with the steel. Steel can also reinforce vertical channels so that their thickness can withstand high pressure.

Bimetal best radiators can transfer high pressure and long-term load, they are resistant to hydraulic shocks and have a high level of heat transfer. Operating pressure is 35 atmospheres, and crimping - almost 52. And due to the fact that the capacity of bimetallic sections will be less than aluminum, this has a positive effect on thermal inertia. As the test shows, the most efficient heating radiators are reliable in multi-storey buildings. After assembly, such best heating radiators are painted with enamel powder, for curing they are heated and maintained at 180 degrees Celsius. With a maximum coolant temperature of 110 degrees, this will be enough.

We propose to study the comparison of heating radiators, the table (Table 1) will show all the strengths and weaknesses various kinds radiators.

After all, the question is what better radiators heating may be relevant for a long time, and only a specialist who is familiar with your heating system can fully answer it correctly.

In more detail about the choice of bimetallic heating radiators in the material -

For right choice heating radiators, you need to know about their main technical parameters. Otherwise, the result may not meet expectations. There are not so many really important parameters for radiators, so even a non-professional can easily understand them.

Features of the choice of heating devices

Now people no longer need to hide or, because modern appliances can become a worthy decoration for any interior. Radiators that are sold today may differ in color, size, material of manufacture and general style of execution, so it will not be difficult to choose the most suitable option.

Attention! Despite the fact that we are used to batteries light colors, the heat dissipation of black appliances is approximately ¼ higher due to color alone. Although when choosing a color it is better to focus on the design of the home and personal preferences.

With regards to the form, it must be streamlined. For security purposes, from sharp corners it is advisable to refuse altogether, especially if children live in the house. Before buying, check out the strengths and weaknesses of each of the existing types of radiators to determine which one is more suitable for a particular room. The first thing you should pay attention to is the working pressure of the devices.

Depending on the material, radiators are divided into:

The pressure mentioned above, the heat transfer coefficient, heat capacity, resistance to mechanical and chemical damage, as well as the service life depend on the material.

Radiators in the interior

Also pay attention to the method of connection to the heating line. The connection can be side, bottom and universal. It is characteristic that in modern radiators all these connection methods are provided.

Attention! The environmental friendliness of the material used in the manufacture is also very important. heating appliances. There should be no formaldehyde in the internal elements, and high-quality polymer spraying on the surface is also welcome.

Now in more detail about each material.

Characteristics of aluminum radiators

Heating appliances made of are considered one of the most popular types of radiators. Aluminum is a light and ductile metal, therefore, batteries made from it weigh a little and are characterized by increased heat dissipation.

The devices consist of sections, each of which is a set of interconnected plates. Thanks to this, heat saving is also at a fairly high level here.

Advantages such units are as follows:

At the same time, after turning off the heating, such radiators cool down quite quickly. Among the others shortcomings worth highlighting:

• instability to chemical influences (the problem can be solved by polymer spraying on the inner surface);
• low strength;
• poor quality of the threaded connection in the upper valve to bleed air from the system.

In view of this, before buying, it is imperative to inquire about the operating pressure of the heating system. The maximum pressure of a particular product must be viewed in the data sheet, because for different models it is different.

But still, according to its characteristics, aluminum is excellent for the manufacture of radiators, and its fusibility has made it possible to significantly expand the lineup. Today you can choose exactly the battery that fits perfectly into the interior of your home.

Aluminum heating radiators

Characteristics of bimetallic batteries

The main difference between bimetallic radiators is the use of two different metals in the manufacturing process - steel to create the core and aluminum to assemble the case. Thanks to this, the rod is very durable. Another advantage of such products is the high working pressure, which can reach 50 (!) Atmospheres. Moreover, steel perfectly "cooperates" even with the water in which there are various impurities, while aluminum heats up quickly and gives off maximum heat.

In a word, the use of two metals at once made it possible to obtain radiators that have the advantages of each of them. Therefore, it is quite obvious that the cost of these devices is the highest among all possible options.

Attention! are used mainly for heating industrial and public facilities. In residential buildings, they are rare due to the high cost.

The service life is 20-25 years, which is quite normal.

Characteristics of cast iron radiators

Such batteries are the most common and known to every option, since they are installed in most standard apartments. Agree, old cast iron appliances can hardly be considered stylish and attractive. New models look better, but in terms of aesthetic indicators they are still significantly inferior to devices made of other materials.

As you know, cast iron is very heavy. Batteries made from it weigh a lot, which cannot but affect the complexity of transportation and installation.

Consider their main Benefits.

But cast iron has limitations, among which:

• significant weight;
• slow heating;
• unaesthetic.

Attention! Despite the abundance of more modern analogues, many people prefer to install cast iron batteries, trusting what has been tested for decades.

Prices for popular models of cast iron radiators

Cast iron radiators

In the manufacture of these devices using low-carbon steel. In order to protect the surface is coated with a special enamel. If good quality, then they have excellent operational parameters, including:

• strength;
• reliability;
• resistance to corrosion;
• durability;
• resistance to various kinds of aggressive substances.

Such batteries can be tubular and panel.

Tubular appliances

They are used to assemble steel pipes with high quality polymer coating. The maximum load that the devices can handle depends solely on the thickness of the pipe walls. It is desirable that the pipes are made of stainless steel.

The service life of tubular devices significantly exceeds that of panel devices and is about 30 years. It is possible to connect in all the ways described above. The working pressure is 10-16 atmospheres, more detailed data should be clarified in the product data sheet.

Prominent representatives of tubular radiators are models manufactured by Loten:

• Loten Gray V;
• horizontal LotenGrey Z.

These radiators are made of steel profile pipe having a rectangular cross section. In addition to providing comfortable heating, the presented radiators demonstrate the latest trends in the design of heating devices, perfectly fitting into the interior of any home.

When creating Loten tubular radiators, there were two main ideas:

• to create high-quality heating equipment: for the manufacture of radiators, high-strength metal with a wall thickness of 2.5 mm is used, due to which these heaters have a working pressure of 16 atm. Radiators withstand a test pressure of 25 atm;
• at the same time turn the battery into stylish element the interior of housing, office space, public areas, etc.

The presented models of heaters can have a different number of sections, from 4 to 12. The length of the sections varies from 750 to 2000 mm. The price of each heating element is directly dependent on the following parameters:

• number and length of sections;
• connection type (side/bottom).

Without extra charge, you can purchase radiator models painted in colors that are at the peak of popularity regarding interior design:

• matte black;
• classic white;
• soft beige;
• concrete grey.

However, lovers of a bright environment can order any other colors and shades.

The presented models of radiators are suitable for connection to a central as well as an autonomous system. The size range is really wide, you can equip the presented radiators as a cozy small one-room apartment, and a spacious country mansion.

Each model can be with side or bottom connection. Heating systems that are suitable for this battery can be:

• single-pipe;
• two-pipe.

The high quality of the material and the laconic style of the products will allow them to take place for many years not only in the apartment, but also in the list of your preferred interior items. Their peculiarity is that they have a long service life (warranty - 5 years, service life - 30 years), so you will not have to think about changing batteries soon. So, you can confidently trust the manufacturer, and make a choice in favor of the considered devices.

Panel devices

As the name suggests, such radiators are made in the form of panels. To do this, a certain number of steel plates are connected to each other. Thanks to this assembly, a high heat capacity is achieved, while the thickness of each individual plate is negligible. In addition, they weigh a little and provide the ability to connect in all available ways.

Attention! Before buying new heaters, look at how your old ones are connected. It is advisable to have new batteries as well.

The cost of panel radiators is slightly higher than the average, the operating pressure is 10 atmospheres. According to experts, such units are best used in autonomous heating systems. As for city apartments, the use of such batteries is unacceptable here due to too high pressure in the central system.

Steel radiators

As a conclusion

It should be noted that any of the described types of batteries can be used for residential heating systems. Although the purchase of bimetallic devices is often impractical, because their advantages are almost the same as those of aluminum, and the cost is many times higher. Therefore, it is better that they continue to remain in industrial and public facilities.

It is undesirable to install aluminum appliances in apartments due to pressure drops in the system that negatively affect the metal. The optimal and proven option for apartments for years is cast-iron batteries. One way or another, you need to focus on financial capabilities and personal wishes.

For those who do not want to dive into independent calculations, we recommend using a special calculator for calculations, which takes into account almost all the nuances that affect the efficiency of space heating.

Radiators are the main elements of the heating system, organizing the flow of heat transfer from the coolant to environment. It is they who are entrusted with the task of heating the premises by transferring up to 90% of the total volume of heat released during the operation of electrical elements (electric furnaces) or fuel combustion (boiler room, stove heating private houses). Initially, the bulk of sectional heaters was cast from cast iron, which has good strength characteristics and immunity to temperature changes. However, such systems had a lot of flaws, since thick walls and discontinuities (in the form of pores, shells, and other casting defects) led to low efficiency or rapid destruction of such structures.

To date, in addition to improving the process of obtaining cast iron batteries, radiators from the following metal groups are widespread:

• aluminum - the most energy-efficient type, having an 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 - are made mainly in the form of panels, have an 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 following the range of manufacturing companies, usually do not have problems choosing radiators for houses and apartments. However, the bulk of consumers are "pioneers" in this segment, and they know about the principles of choice only by hearsay. Moreover, over the past 5 years, this category of the market has almost doubled, having got hold of hundreds of fresh models of stacked batteries, as well as the opening of a number of new companies. Therefore, having carefully studied the current range, we have compiled for you a rating of the most best radiators heating, the purchase of which will not only increase the efficiency of the heating system, but also a profitable investment of own funds.

The best bimetallic heating radiators

Bimetal radiators have good heat dissipation and 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 Global (Italy), Rifar (Russia), Sira (Italy) and Royal (Italy).

3 Sira RS Bimetal 500

The best heat dissipation. Silent operation
Country: Italy
Average price: 5 640 rubles.
Rating (2019): 4.5

SIRA RS BIMETAL 500 is a high-quality bimetal sectional heater with a heat output of 201 W per element. Such a good indicator is due mainly to the successful design of the product, and therefore, in a large assembly, it is capable of heating up to 40 square meters premises.

As advantages of SIRA RS BIMETAL, the reviews include a pleasant design, high-quality powder coating and reliability in all aspects of operation. True, the operating pressure does not particularly shine with magnitude - the battery is capable of withstanding up to 40 bar, but this is enough for installation in apartments for centralized heat supply, and in private houses with an independent source of heating. Of the minor shortcomings, only the sensitivity of the bimetal to the composition of the coolant can be distinguished, although, to be honest, the consequences of such influences are negligible. Otherwise, this heater seems to be very good option for a purchase that combines many positive aspects.

2 Global STYLE PLUS 500

High build quality. User Popularity
Country: Italy
Average price: 6,400 rubles.
Rating (2019): 4.8

One of the brightest representatives of the Global company, which got into the rating due to balanced performance parameters and a good combination of them 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 to the environment, which, according to the company's experimental calculations, is suitable for fairly spacious rooms ranging from 30 to 37 squares. The maximum allowable operating temperature of the coolant in the system can reach 110 degrees Celsius, and the pressure - no more than 35 bar, and therefore prefabricated radiators are recommended to be used only in central heating systems.

Table of advantages and disadvantages of different types of radiators.

Radiator type	Advantages	Flaws
Cast iron	Low price Good thermal conductivity Not demanding on the quality of the coolant Durability (up to 50 years) Keep warm for a long time after turning off the heating	Warm up slowly Poorly tolerated water hammer Uses a lot of water for heating Have a large mass fragile Collect a lot of dust Requires frequent maintenance (painting)
Aluminum	High heat dissipation Beautiful appearance (design) Light weight (can be hung even on drywall) compactness Low price	High requirements for the quality of the coolant (water pH should not be less than 7.5) Corrosion resistant Air pockets may form
Steel	Fast heating The highest heat output Low inertia Affordable price	Rust forms (steel rusts in water) Demanding on the quality of the coolant May burst due to water hammer over 13 atm
Bimetallic	High strength Fast heating Excellent heat dissipation Neutrality to the chemical composition of the coolant High pressure resistance Long service life (up to 20 years) A light weight Good appearance	High price Demanding on water quality

1 Rifar Monolit 500

The best ratio of price and quality. Operating pressure 100 bar
Country Russia
Average price: 5 100 rubles.
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 Rifar is very scrupulous about the quality of its entire range of products. Other advantages of the model include 135 degrees of permissible operating temperature, a pleasant design, as well as 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 corrosion resistance. They are light, easy to install and have an attractive appearance, however, they withstand less pressure and are sensitive to the composition of the coolant.

3 Thermal RAP-500

Best price. Maximum working pressure 24 bar.
Country Russia
Average price: 3127 rubles.
Rating (2019): 4.6

The domestically produced radiator from the Termal company is distinguished by the lowest price in the segment, however, in terms of operating parameters, it is practically not inferior to the recognized leaders of the category. The main advantage of the RAP-500 is the high specific heat transfer of the section, equal to 252 W. This is the most big indicator in the rating, indirectly indicating high efficiency 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 reasons. Of the other parameters of the radiator, it is worth highlighting the possibility of working 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 gr.
Country Russia
Average price: 2,442 rubles.
Rating (2019): 4.7

Another representative of the Rifar company got into the rating due to a set of good performance characteristics, however, with a slight overestimation of 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 central heating.

In terms of heat dissipation, Rifar Alum 500 is slightly inferior to its competitors: one section is capable of generating up to 183 W of heat. In the aggregate (if there are 14-16 elements in the assembly), such a battery will be effective on living space up to 26 square meters. It is noteworthy that for the correct operation of the section, 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 a convenient method of wall mounting.

1 Global Vox 500

The best choice for the climate of the Russian Federation. 10 years warranty
Country: Italy
Average price: 680 rubles.
Rating (2019): 4.9

Despite its 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 most high performance heat transfer (up to 195 W), which in practice turns into significant savings on the number of sections during assembly. In addition, Global's 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 peculiarities 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, a 2-step painting technology is applied. The devices are so good that their installation can be carried out in heating systems with a working pressure within 16 atmospheres (the norm according to SNIPs is no more than 12 atm. at the level of the 10th floor and above) with an allowable short-term jump twice as much. Destruction occurs only at 48 atm., So that the inhabitants of the 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 low cost due to cheap material and well-established production. In addition, such heaters require less coolant and practically do not take up space, but their heat transfer is slightly lower than that of other types.

3 Purmo Compact 22 500

The largest heat transfer rate (5572 W). Possibility of heating rooms up to 50 sq. m.
Country: Finland
Average price: 7,302 rubles.
Rating (2019): 4.8

In the segment of steel heating radiators, there is a surprisingly even selection of options by characteristics. Often, as in this case, all the 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 price cuts by competitors.

The configuration of the dimensions of this panel is almost identical to the opponents (500x102 mm), and in terms of nominal parameters of pressure in the system (10 bar + 13 bar of pressure pressure) and coolant temperature (110 degrees Celsius), it does not differ much from the nominal value. 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 ranking was the question of the quality of the Purmo Compact exterior finish. User reviews contain information about the gradual yellowing of the coating, as well as the not always clear fit of the elements to each other, which causes significant gaps in the panel.

2 Buderus Logatrend K-Profil 22 500

Nice design. Operation with heating medium up to 120 °C
Country: Germany
Average price: 4,720 rubles.
Rating (2019): 4.9

The Buderus Logatrend K-Profil 22 500 panel kit loses to the segment leader solely in the cost component, compared at the performance cutoff. With the same length-to-thickness ratios, as well as the maximum pressure in the system (10 bar), this sectional heater provides the possibility of circulating a coolant with a temperature of up to 120 degrees Celsius, thereby compensating for some deviations in the heating system.

As for the opinions of users, they often notice the equally good appearance of the panel, the ease of installation and further operation. A small nuance is that the radiator metal is sensitive to the composition of the coolant, which can lead to accelerated battery wear long before the warranty period expires. The opposite cases also take place (an increase in the working resource), but this is either the merit of the consumers themselves, or the 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 rubles.
Rating (2019): 4.9

The panel heater Kermi FKO 11 500 is the most budgetary solution to the issue of purchasing a metal heater. And it is worth noting, not the most in vain. Despite the low cost, this model has a very solid energy efficiency. With a length of 400 to 3000 millimeters, its heat transfer can be 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 in order to reach its nominal parameters. The working pressure at the peak can reach only 10 bar, however, this quantitative indicator is enough to withstand rare water hammers in the system. Differs Kermi FKO and good design– Consumers like to notice this positive feature in their reviews.

The best cast iron radiators

3 Viadrus Style 500/130

Great design. High quality product
Country: Czech Republic
Average price: 26,647 rubles.
Rating (2019): 4.7

The Viadrus Styl 500/130 heating radiator is the most expensive model in the ranking, but at the same time it is very popular with consumers due to its beautiful appearance and high performance standards. The peak temperature of the coolant here can reach up to 115 degrees Celsius, leaving a small reserve in case of changes in the pressure parameters in the circuit, which is not uncommon for central heating. In general, the pressure can reach up to 12 bar, and pressure testing - up to 18, which is quite a normal result for cast iron batteries.

Judging by consumer reviews, the only truly serious nuance of Viadrus Styl is the coolant flow parameter. Due to the thin-walled design (intended to increase heat dissipation), up to 800 milliliters of water is required for efficient operation of one section. This is not critical for residents of apartments with central heating, however, for "private traders" it results in the need for periodic maintenance of the system (for example, adding water to the expansion tank).

2 Konner Modern 500

Good heat transfer performance. The optimum ratio of price and quality
The country: Germany (made in China)
Average price: 3 860 rubles.
Rating (2019): 4.8

The sectional cast-iron radiator Konner Modern 500 is an even greater “spender” of the coolant than the previous representative of the rating, but it has much better energy efficiency parameters. For the normal operation of one section, 900 milliliters of water is 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 able to heat up to 27-30 square meters of a room, which is the most optimal result in the collection.

Regarding the working pressure in the system, the Konner Modern 500 has a standard value of 12 bar, used mainly for installation in apartments with central heating. The main prerequisites for popularity among users in this case were not only operating 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 rubles.
Rating (2019): 4.8

Certainly one of the best cast iron radiators for installation in an apartment (and one of the most inexpensive) is the domestic model STI Nova 500. With small overall dimensions, this heater provides heat transfer at the level of 1200 W, which is enough for high-quality heating of 20 square meters of a room. The radiator also performs very well when pressure is applied, 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 all possible manifestations of jumps in the main parameters, especially when working in an individual heating system.

According to consumers, another important advantage of STI Nova is the appearance parameter. The manufacturers managed to create a pretty nice design that can fit into any interior. In addition, these radiators are very unpretentious in maintenance and easy to install, even despite the rather large weight.

In the article, we will consider what kind of heating radiators are for an apartment. How to choose a device? Which technical specifications lean? Let's figure out which heating radiators are best for country house. Let's find out how aluminum, bimetallic, cast iron, steel heating radiators differ, which ones better meet individual requirements?

NEED TO KNOW! The choice depends on the components of the coolant. In DSP, the coolant is often of poor quality. When in contact with liquid, aluminum is corrosive, so it is not suitable for an apartment building.

On the features of centralized and autonomous heating systems. What to pay attention to?

Residents of apartment multi-storey, private houses (dachas, cottages) use different heating systems (OS). Each has features, advantages, disadvantages. Keep in mind: for each OS, you need to select radiators in your own way. An unsuccessful purchase of equipment will lead to low heat transfer, a short service life, and quick damage.

water hammer(water hammer) - a sharp jump in pressure in a system filled with water. The reason for it is the rapid change in the speed of the flow of water. The consequences of water hammer: the appearance of longitudinal cracks in the pipeline.

Depending on whether in apartment building you live or private, heating can be:

• Central (DSP). Heat is supplied to several buildings, apartments from a single source (boiler room). The pipeline distributes the coolant, supplying to consumers. After the heat is removed, the carrier returns to the source (heat generator).
• Autonomous system useful for serving residents of a private house. It is also used in cottages, dachas: they are not connected to the DSP. To heat the coolant, a boiler or boiler is mounted. Next is the control unit, piping system, batteries. Advantage autonomous control in the function of setting according to needs: adjustment of the heating temperature, automatic maintenance preset settings. Disadvantage: high price of the battery, installation work, complex maintenance.

What are the batteries for an apartment, a private house?

Material is the main criterion by which equipment is selected. Affects heat transfer, pressure, cost, service life, strength, reliability.

By material:

• Bimetal. Undemanding to the coolant, focused on long-term use. Expensive.
• Cast iron. The indicator of residual heat retention is 30% (for other varieties - 15%). Slowly heat up, slowly lose temperature. Reliable, corrosion resistant.
• Aluminum. They heat up quickly and lose heat quickly. Useful in autonomous systems. Characterized by high thermal power, reasonable price.
• Steel. They are compact, have good heat dissipation, are durable, and are slightly oxidized from a low-quality coolant.

By installation type:

• Wall. The most common radiators in apartments, cottages, cottages, private houses. Mounted on the wall.
• Plinth. They are mounted in metal boxes, taking up space instead of a standard plinth. Almost do not occupy the area of ​​the room. Inconspicuous, will not stand out from the decor of the room.
• Intrafloor. Water convectors save space: they are built below the floor level.

Heating radiators - which are better for an apartment?

When choosing a battery for installation in an apartment, pay attention to main technical parameters:

• Heat dissipation characterizes how efficiently the device will cope with space heating. When selecting, take into account heat losses (they are affected by the thickness of the walls, the size of the window and doorways), the volume of the room. In sectional models, power is indicated per section. The calculation of the number of fins will accurately determine the required level of heat transfer. Thermal power one section averages 0.15–0.2 kW.
• Operating pressure it is important that the hardware can work on your system. The pressure depends on the material. Incorrectly selected pressure will cause water hammer damage.

• Material or coating capable of protecting against wear, leakage. Thick walls, primers extend service life. The ability to connect a battery to work with an aggressive coolant will expand the scope of operation.
• Design heating equipment. Consider how the heating equipment will fit into the surroundings. Due to the choice of models, the device can be selected for various styles of design, colors.
• Weight it is worth considering immediately before buying: can you transport the unit to the house, fix it on the wall, connect it without causing a breakdown. The most massive cast-iron batteries, lighter aluminum (the mass of one segment is up to 2 kg), steel (about 2.5 kg).

Options for choosing radiators for a country house

Unlike central heating apartment buildings, the autonomous OS of private dwellings is much less demanding on pressure. Due to this, it becomes possible to purchase equipment designed for low pressure. Models with thin walls are suitable: for example, aluminum.

NEED TO KNOW! Inexperienced cottage owners are faced with freezing fluid in pipes. This leads to the appearance of chips on the body: it bursts. To avoid this, drain the water.

Due to the smaller distance between the heat source and the battery, heat loss in autonomous heating systems is small. Equipment in a private house must be adapted to high temperature coolants.

Cast iron radiators - which are better? Advantages disadvantages

Cast iron is a strong reliable material, heavy and durable. Cast iron heating equipment is used in apartments, private houses, cottages, dachas. The material takes a long time to heat up, which will cause discomfort at the beginning of the heating season. But it works in the opposite direction - when disconnected, the batteries remain warm for a while.

Advantages of cast iron models:

• Long cooldown. The thick body retains heat - the heating season will end later than the neighbors.
• Reliability and durability. In old houses there are cast-iron batteries that are 50 or more years old.
• Corrosion resistant. The material is undemanding to the quality, type of coolant.

Flaws:

• Big weight. Difficult to deliver and install.
• The price is higher than that of steel and aluminum.
• Long heating. It will take time to warm up.

Bimetallic heating radiators - which ones are better? Advantages disadvantages

A feature of bimetal devices is that they consist of two materials. Aluminum shell, steel core. Strong, durable. Resistant to corrosion and water hammer, easy to install, have a high heat transfer. Due to the relatively high price and ability to withstand high pressure, they are installed in apartment buildings. Which bimetallic heating radiators are best for an apartment - trademarks Halsen, Radena, Bilit.

Advantages of bimetallic equipment:

• High resistance to corrosion: steel components protect against harmful effects.
• High heat dissipation due to the aluminum surface. Aluminum heats up quickly.
• Long service life. On average, bimetallic devices operate for 25 years.

Flaw one - a high price compared to aluminum, steel, cast iron.

Aluminum heating radiators - which are better? Advantages disadvantages

Suitable for private houses, cottages with an autonomous OS: they are not designed for high pressure due to the fragility of aluminum. They are inexpensive. They heat up quickly and cool down just as quickly. The service life is about 15 years.

Which radiators are better: aluminum or bimetallic?

Aluminum appliances characterized by a low price. Are suitable for installation in private houses, cottages, dachas. With high heat output, prices are relatively low (if you look at Russian manufacturers - Halsen, Royal Thermo, Radena), the design will fit into the environment.

The advantages of aluminum models include a relatively low price (there are expensive options and analogues on the market for those who want to save money), a high heat transfer rate. Disadvantages: demanding on the acidity of the liquid (destruction of the walls is possible due to the susceptibility of the material).

Bimetallic batteries made of two materials: steel on the inside, aluminum on the outside. Designed for a service period of approximately 40 years, reliable, expensive relative to other varieties. Unpretentious (no special requirements for water). Inside and outside coated with a primer to prevent corrosion.

Bimetallic ones are suitable when a durable unit is required. The only drawback is that the price will not suit everyone.

Sectional or steel - which is better?

Sectional heating batteries are installed in several blocks: they are connected into a single structure. It is convenient and practical: it will allow you to control the efficiency of space heating. Difficult to install: leaks due to incorrect connection are possible. Install such heating equipment in private dwellings with an autonomous OS. This is safe because sectional models are less protected from water hammer.

Dimensions steel (panel) aggregates are known in advance (find out in technical specifications or seller). When choosing, be guided by the parameters of an apartment, a private house (amount of free space, length and depth of niches). The price of panel units is higher. The pipes of most models have a primer that prevents corrosion from low-quality coolant. The coating increases the service life. Are mounted in apartment buildings (stand-up system).
