When the question of which heating radiators is best to choose for a private home appears on the agenda, there are many who nostalgically recall Soviet cast-iron “accordions” - although bulky, they are hot and warm the room well. Indeed, at one time such batteries worked “excellently,” but now they are deteriorating and are considered obsolete. They have already been replaced by new, more efficient, convenient and cost-effective models.
But the main problem the fact is that there are many diametrically opposed opinions regarding new radiators. And in practice it’s the same: you go to neighbors who have installed modern radiators at home - some are warm, while others are cold. At the same time, both places have almost identical heating batteries - that is, which of them is better for a private home does not always depend on the specific model. In our article we will try to figure out which heating radiators are best for a private home.

Features of heating networks in a private house
Unlike multi-apartment buildings, an autonomous heating system is installed in a private house, that is, it does not depend on the central boiler room, which means that the pressure in the network and the temperature of the coolant will be completely different. Therefore, when choosing a radiator for a private home, you need to consider the following points:
- In private houses, the pressure on the coolant, and with it on the tanks and radiator pipes, is much less than in multi-storey buildings. Thus, the batteries do not experience overload, so you can choose any, including thin-walled models.
There is a horror story among residents of apartment buildings about pipes bursting due to water hammer due to sudden pressure surges in the water supply. In fact, no water hammer even in apartment buildings It can’t be, not to mention heating systems in cottages. But in private homes, especially those in which people do not live all the time, another problem may arise - freezing of water in the pipes. It is in this case that the batteries may simply burst if you forget to drain the water from the system before leaving.
Even cast iron batteries cannot always withstand system freezing Source ir-leasing.ru
- In a private house, the length of the pipeline from the heat source (boiler, stove) to the radiator is very short compared to multi-story buildings. Therefore, heat loss is minimal, and the coolant is more heated. Conclusion: in a private house there should be radiators that can withstand high-temperature coolant.
- A little liquid is needed to fill the heating system, so you can add antifreeze or ethanol. This protects pipes and radiators so that they do not freeze if the boiler is turned off for a long time.
Adding antifreeze to the heating system Source homediz.info
- When choosing heating radiators, which ones are best for a private home should be determined based on the size of the heated area. In cottages there is a lot of space, and therefore energy consumption for heating is also large. It is advisable to install batteries that will warm up your home at a minimum cost.
Guided by these simple rules, you can buy the optimally suitable model.
Classes of heating radiators and their types and features
The principle of operation of a radiator is to transfer heat to the surrounding space from the coolant fluid circulating in this heating device.
The autonomous heating system (AHS) consists of:
- boiler;
- pipelines;
- thermal elements.
Autonomous heating system Source gidroguru.com
The table shows the main types of thermal appliances:
Besides, heating devices are divided into the following classes, let’s consider a unique rating of heating radiators from this side:
Sectional
They consist of heating sections that are connected to each other. The more sections, the more heat they will transfer to the surrounding space. To prevent the room from overheating, special thermostats are installed on the radiators to regulate the temperature.
Thermostatic tap for temperature control Source drive2.ru
Standard cast iron radiators are also sectional: heat is transferred from them in the form infrared radiation, evenly distributed throughout the room - top, bottom and middle. Such batteries have large dimensions and thick walls, which accumulate enough heat so that it is emitted in the infrared spectrum. It is this method of heating that is considered optimal for human health, although it must be borne in mind that part of the heating also occurs through convection.
Thanks to the thick walls, such batteries have high thermal inertia - therefore, after turning off the AOS, the radiators remain hot for a long time. Cast iron is not very susceptible to corrosion and is not afraid of harmful impurities in the coolant - the service life of such devices reaches 50 years. One of the disadvantages is the heavy weight.
Aluminum radiators have good heat transfer (1/2 radiation + 1/2 convection) and quickly warm up the room. Compared to cast iron, they are more lightweight, and in general, the ability to transfer heat into the room is several times higher than that of cast iron and steel.
Sectional radiator Source isu.org.ua
Additional benefit modern models It is possible to regulate the temperature using a valve with a thermal head. The metal surface is covered protective coating, which allows you to increase the service life. The cost of aluminum radiators is low, and therefore the prices are more affordable.
High overloads aluminum radiators do not withstand, therefore they are not used in central heating systems (CHS). They break due to pressure surges, the presence of rust or sand particles in the coolant. Chemical additives are not allowed in liquids.
Bimetallic heating radiators consist of external aluminum plates and steel pipes located inside the sections. They are valued for their reliability and durability, but are not cheap. Equally well suited for centralized and autonomous heating systems.
Radiators are also produced that have only steel-reinforced vertical pipes. These are no longer completely bimetallic devices; they are less corrosion resistant. Among their advantages, it is worth noting their high thermal conductivity, which is higher than that of real bimetallic radiators.
Tubular
Steel tubular heating devices give off heat well, are economical in terms of energy consumption, and heat up quickly. Their disadvantage is that they are sensitive to oxidative processes. If the coolant fluid does not fill the steel radiator reservoirs, it will begin to corrode. Another weakness of a steel radiator is its hypersensitivity to water quality. Even if the water is considered good by usual standards and can be drunk, it is recommended to install filters to minimize the formation of scale.
A steel tubular radiator can be placed in a narrow niche Source bouw.ru
The sizes of steel tubular radiators are from 30 cm to 3 m. The number of rows of tubes is 1–9. They are considered very reliable - the permissible operating pressure for devices from a number of Russian manufacturers reaches 15 atm. Radiator reservoirs are designed to hold a large volume of liquid, so they quickly reach the required temperature levels when it is necessary to increase or decrease power. The method of heat transfer is radiation and convection.
Steel radiators are also used as heated towel rails, which, in addition to drying clothes, provide additional heating in bathrooms

Floor radiators-benches on support legs are steel tubular heating devices with a seat in the form wooden board upstairs. They are connected to the heating system in the same way as conventional radiators. They can also serve as the main heating device in rooms such as the kitchen, bathroom, hallway.
Panel
These steel radiators are panel rectangular shape, acting as a heating device. The panel consists of 2 ribbed sheets welded to each other; plates with a U-shaped relief are placed inside.
Steel panel radiator Source 999.md
Operating pressure is 6–8 atm, high sensitivity to pressure changes, therefore they are used only in autonomous heating systems for residential and commercial premises. Such radiators can consist of 1, 2, 3 heating plates. React quickly to temperature changes. The main method of heat transfer is convection. The choice of sizes of such devices is wide enough so that they can be selected for a room of any size.

Ceiling thermal panels consist of steel plates to which pipes intended for coolant are welded. Their use is advisable in rooms with high ceilings from 3 to 20 m. Heat transfer is carried out by radiation.

Lamellar
Plate heating devices consist of horizontally arranged pipes to which metal plates are welded, thereby increasing the surface area for heat transfer. Heat transmitters can additionally be covered protective covers. The advantage of such radiators is their reliability - they can be used for centralized and autonomous heating. The main method of heat transfer is convective, so the space is heated unevenly: it is much warmer on top. They are mainly used for offices, corridors, garages and utility rooms, but there are also models for residential premises.

Rules for the location of batteries in the house
In order for the system to work properly, installation rules must be strictly followed. Although the installation technology is not complicated, it has its own nuances, so the work must be carried out by specialists.
Important! If radiators are installed incorrectly, they are not covered by the warranty.
In order to avoid heat loss and uneven heating premises, when installing devices it is necessary to observe the indentations and choose the correct location:
- The most suitable option for the battery is considered to be a place under the window, i.e. where the heat loss is the most significant. The radiator width must be at least 70% of the window width. Mounted clearly in the middle.
Correct battery placement Source koffkindom.ru
- Leave at least 10 cm from the battery to the windowsill, as well as to the floor. Optimal distance between the floor and the radiator - 12 cm. It is not recommended to leave more than 15 cm.
- The battery is fixed at a distance of 5 cm from the wall.
- You can stick heat-reflecting material behind the radiator - then some of the heat will not go into the wall, but will return to the room.
- If the radiator is planned to be placed not under the window sill, but on the wall, then the distance between them should be at least 20 mm.

Calculation of the number of sections
It is not necessary to look for the most expensive heating devices to make the room comfortable. The main thing is to correctly calculate the number of sections. If the rooms are standard, then this greatly simplifies the calculations.
Often they resort to calculations based on the volume of space because they are simple, but at the same time give fairly accurate results.
- 1 m³ requires 41 W of power. If good double-glazed windows are installed and heat loss is minimal, then the indicator drops to 34 W.
- Room volume (m³) = area (m²) × height (m).
- Required heating power for the entire room (W) = room volume (m³) × 41 W (or 34 W).
- In the technical data sheets of devices, manufacturers indicate the heat transfer of one section.
- The total power (the value calculated in point 3) must be divided by the heat transfer of one section. The resulting number is the number of sections.
For example, the required thermal power is 2890 W, and the heat output of one section is 170 W. Then for this room you need to purchase 17 sections.
In a non-standard room, calculations are made according to more complex formula Source rmnt.mirtesen.ru
If the room is non-standard, the calculations become more complicated. To calculate the total power, the features of double-glazed windows (double or triple), thermal insulation parameters of the walls, the ratio of the sizes of windows and floors, ceiling heights and other parameters are taken into account. Designers calculate all this using specialized software.
Which radiators to choose for a wooden house
Heating wooden house(we are talking primarily about log houses), indeed, has its own characteristics, since the thermal conductivity of wood is low and depends on its species. In addition, it is necessary to ensure maximum fire safety. But in general, the issue of providing heat, as well as safety, rests primarily on correct installation heating systems, choice of boiler and number of radiators. There are no restrictions on the type of radiators here: steel, cast iron, bimetallic, aluminum - all of them can be used in a wooden frame.

Which heating batteries to choose for a private home and cottage
It is not difficult to select batteries for a private home, because they work autonomously heating system occurs without significant overloads such as those experienced by a centralized system. Here you can connect any radiators, focusing on required power, quality, efficiency, cost of the device.
Many owners of private houses prefer aluminum radiators. They are cheaper than cast iron, more economical to operate and have higher heat transfer rates, and the sensitivity of aluminum devices to water hammer in autonomous system heating can be neglected.
If you want to choose batteries based on the brand name, then you can take into account the unspoken rating of aluminum heating radiators for a private home. Top positions here belong to brands Calidor, Global, Rifar, STI, which are well suited for operation in Russian climatic conditions.
Modern radiators will provide even in the coldest weather comfortable atmosphere in room Source nehomesdeaf.org
Steel radiators are no less common, which is not surprising, because they are reliable, affordable, able to warm up quickly and have good heat dissipation. Here, in the ranking of steel heating radiators for a private home, the leading places are occupied by Kermi, Purmo, Zehnder, Sunerzha.
Among the worthy brands producing bimetallic radiators, we can note the Russian Rifar and the Italian Global. Those who decide to purchase cast iron heaters should pay attention to Konner (Russia), Guratec (Germany), Retro Style (Russia).
As a result, all radiators are universal, which means asking the question which heating radiators are best for a private home with gas boiler, is not entirely correct, because when choosing, they are mainly guided by the required power, the characteristics of the room and the possibilities of the budget.

Radiator prices
The cost of heating devices varies significantly depending on the following factors:
- brand and country of origin;
- material and production technology;
- design.
Italian, German, Finnish, Czech batteries are more expensive than Russian ones, but in terms of their technical and operational characteristics the products domestic manufacturer are not much inferior and even superior to many foreign analogues.
Buying heating radiators for a private home is quite expensive. But if you make up correct calculations and choose cost-effective devices, then costs can be significantly reduced.
The average cost of aluminum radiators per section is in the range of 1227–8200 rubles, bimetallic devices – 3000–11900 rubles. The cheapest of them can be purchased at a price of 1100 rubles. The range of prices for steel radiators is also quite wide: from 830 to 60,000 rubles. Steel models costing from 3,500 to 26,000 rubles are popular. Inexpensive cast iron batteries can be purchased for 500–1000 rubles. Cast iron appliances are in demand for RUR 3,000–8,000.
Retro-style batteries can be found from 8,000 rubles.

If batteries are needed for an entire house, then even inexpensive devices cost a pretty penny. In addition, costs will be added for related products: valves, thermostat heads, brackets and other parts.
Conclusion
Correct installation of the heating system in general and any of its components in particular requires specialized knowledge, without which it is difficult not only to install, but even to select all the components. As a result, this issue should be addressed to professionals - experienced craftsmen will carry out accurate calculations and they will take into account not only the footage, but also other features of the room, and will tell you which heating is best for a private house in your case. They dismantle the old batteries, quickly and, most importantly, correctly, install new ones. They will check the operation of the heating system and provide technical and warranty documentation.
Gone are the days when we all lived in buildings equipped with the same radiators. These cast iron monsters were large in size, but quite reliable and efficient in operation. Another problem they had was the appearance and design: Soviet times We didn’t think much about beauty, because the main thing is that the battery heats constantly and stably. Today the situation has changed dramatically: on the market you can find more technically advanced radiator heating systems that not only work efficiently, but also look very good in appearance.
Our proposed rating includes best radiators heating systems designed for installation both in private houses and in apartments connected to a central heating system. The selection covers: bimetallic, aluminum, cast iron and steel radiators.

What should you consider when choosing heating radiators? What is the best radiator to buy?
When purchasing new radiator heating systems, be sure to find out what materials the device is made of. For example, when installing a new battery in an apartment, two options, namely radiators made of steel and aluminum, should be discarded immediately: the former suffer greatly from pressure changes, and the latter from corrosion. Bimetallic models are good for everyone, but they are much more expensive than other types of products. If reliability is important to you and you don’t want to overpay extra money, then you should stick to the usual heating systems made of cast iron: you can find quite a few on the market decorative items made of this material with an attractive appearance, extraordinary design and at an affordable price.
Selecting batteries for heating in own home- is not at all the same as buying batteries for use in an apartment where the central heating system always functions. Heating a private home involves organizing your own heating system, which, as a rule, is based on a gas boiler. This and other nuances impose certain requirements to radiators.
To help you navigate the issue, Santekhbomb has prepared an article with recommendations. After reading it, you will learn which heating batteries are best for a private home, what you should pay attention to when choosing them, and also get an idea of the main characteristics of the currently most popular batteries suitable for working in gas heating systems.
Features of a gas heating system
First of all, it is worth identifying several features inherent in gas heating systems.
- Low operating pressure.
- Absence of pressure surges and water hammer due to the closed circuit.
- The ability to use good quality coolant, change its type or properties.
Based on this, such common types of heating batteries as cast iron and bimetallic should be immediately “swept away” from the selection. Yes, they are wonderful in their own way, but there is no point in using them in a closed system. Bimetallic ones, despite all their advantages, cost a lot - more expensive than aluminum and often even cast iron analogues, which will make their purchase completely impractical. Cast iron ones are simply not suitable for autonomous heating on gas. It's all about their high thermal inertia - because of it, you won't heat up the room quickly, and the efficiency of cast iron is such that using it in your home will be too expensive. This will also prevent the system from working. automatic adjustment temperature, if any. The main advantages of cast iron come to naught - there will be no water hammer in such a system, as already mentioned, but to ensure good quality coolant will not be difficult.
If you are looking for heating batteries, which ones are best for a private home, the only options left are aluminum batteries. But you should choose them based on your needs. To do this, let’s take a closer look at how exactly they interact with gas system heating systems, what are their main advantages, and what characteristics should you pay attention to before purchasing.
In the current market, which is saturated with varieties of heating devices from many manufacturers, it is sometimes very difficult for the average homeowner who has decided to replace batteries to choose suitable products for their home. Our goal is to help solve this problem and figure out which batteries are best installed in an apartment or in a private house.
Overview of heating radiators
Walking into a large heating equipment store, you get the feeling that there are countless types of heating batteries. In fact, there are only five of them:
- cast iron products;
- steel heaters;
- aluminum radiators;
- bimetallic batteries;
- electric heating devices.
All these types of heating radiators have different specifications, as well as their advantages and disadvantages that determine the scope of their application. Let's take a closer look at each of them, and clearly determine which type of device is best placed where.
Cast iron radiators
This type of water heater, familiar to us from childhood, is still used to this day, despite the emergence of many modern competitors whose technical characteristics are much better. This is due to several reasons, for example, the high corrosion resistance of cast iron and the ability to work in systems with high coolant pressure. In addition, for many people, tribute to tradition is important and, despite any explanations, they are still convinced that cast iron batteries are the best.
This opinion has a basis, since these devices are very reliable and durable; according to these criteria, they have no equal, since they last from 30 to 50 years. In addition, cast iron heaters retain heat for a long time, having great massiveness and inertia. This advantage is also a disadvantage: cast iron batteries take a long time to heat up and take just as long to cool down, so it is very difficult to organize automatic climate control in the room where such devices are installed.
If previously the appearance of cast iron batteries left much to be desired, now many companies offer cast iron heating radiators with different powder coating or with decorative casting.
True, this improvement took traditionally cheap heaters out of the budget category, since similar products are much more expensive. Their other disadvantages are well known: large weight and water capacity, although Lately and they are kept to a minimum.
What’s good about cast iron batteries is that they can be installed everywhere: in an apartment, house, or cottage. But it is best to use them for heating a private house where a gravity system is organized. It itself is inertial and has a large volume of coolant flowing at a low speed. This is exactly what a massive cast iron appliance needs.
Steel batteries
This type of heaters is divided into two types
- panel;
- tubular.
Panel is good radiators for a private home where the operating pressure of the coolant does not exceed 3 Bar. The fact is that their design and manufacturing technology provide for working in a system with maximum pressure up to 15 Bar. This is often not enough in conditions of centralized heating, especially in high-rise buildings.
The panels have good heat transfer, relatively light weight and size, and are also distinguished by their aesthetic appearance. There are also steel radiators with bottom connections, which makes it possible to install them in apartments with individual heating and piping hidden in the floor.
In addition, among all heating devices, steel panels have the lowest cost, so they often remain the only acceptable option. Disadvantages include sensitivity to corrosion and a relatively short service life (up to 15 years).
When is it necessary to deliver steel radiator into the central heating system, it is better to choose a tubular type device that has thick massive walls that can withstand high pressure and water hammer. Therefore, such batteries can be installed anywhere, they are reliable and durable.
Another thing is that the cost of tubular devices is quite high, and there are disadvantages similar to cast iron batteries: inertia, large capacity and considerable weight. Because of this, they are rarely placed in country houses and other buildings with individual heating systems, preferring the same heaters made of cast iron or aluminum.
Aluminum radiators
One of the most popular heating devices - sectional aluminum batteries - are distinguished by the best degree of heat transfer, fast heating and cooling, low weight and remarkable appearance.
All these advantages are realized thanks to the device body made of aluminum alloy. It contains vertical channels with a cross-section close to circular, and on the outside these ducts are equipped with many ribs that intensively transfer the energy of the coolant to the air in the room. In its turn, flat surfaces aluminum batteries produce a uniform flow of radiant heat. Physical properties aluminum make it possible to organize automatic regulation heating power, since inertia in this case is practically absent. A small capacity (up to 0.25 liters of water in each section) also contributes to rapid heating.
Aluminum radiators for the home are easy to assemble and install due to their simple design and low weight of the products. They can be attached to any building structures, even plasterboard partitions. You just need to do the calculations correctly required quantity sections for heating the room, sales representatives or online consultants of online stores will always help you with this.
As for the shortcomings, there are only two. The first is similar to steel panels: a low threshold for maximum operating pressure (up to 16 Bar), which makes the installation of aluminum batteries in centralized heating systems risky. The second is ordinary and electrochemical corrosion of the alloy due to exposure to low-quality coolant from central heating networks. Therefore, aluminum ones are the best radiators for any individual heating systems, where the quality of the coolant is controlled by the homeowner himself, and the pressure in the system is controlled by the boiler automation. But in apartments with central heating It's better to install bimetal.
Bimetallic radiators
In fact, bimetallic batteries are the same products made of aluminum, inside of which there is a welded frame made of steel pipes with thick walls. As a result of this modernization, the shortcomings associated with the quality of the coolant and its pressure were successfully eliminated.
At the same time, the heaters have slightly less heat output than purely aluminum ones, but much more than those of steel or cast iron appliances. Therefore, in the case of centralized systems heat supply for heating, it is better to install bimetal radiators; they will serve for a long time and reliably, while giving off heat much more intensely than other types of devices. But it should be said that the cost of bimetallic batteries is significantly higher than aluminum ones.
Conclusion
Before we draw the line, it’s worth saying a few words about products such as electric heating radiators. They are very effective and easy to install, all they need is a 220 V outlet. Another thing is that the cost of electric heating is quite high, so heaters are often used as additional heat sources.
From the above we can conclude that the choice of batteries largely depends on the type of heating system. If you have the financial opportunity, it is better to install aluminum appliances in a private home as they are the most economical. When this is not possible, then steel panels will do, and with a gravity system - cast iron heating devices. The same applies to apartments with an individual heat source. But in centralized networks Cast iron or bimetallic batteries, as well as tubular steel ones, would be appropriate. The choice largely depends on the homeowner's budget.
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 large quantity 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.
