To keep the house and apartment warm and comfortable during the cold season, it is important to correctly design and install the heating system. And the radiator is one of the important components. Thanks to correctly selected equipment, it is possible to ensure the efficiency of the heating system.
But among the rich assortment of batteries presented by manufacturers such as Prado, Konrad, Global Style, Tenrad, Viadrus, Konner and others, it’s hard to navigate, right?
You do not know how to avoid mistakes when choosing and what points should be paid attention in the first place? We will help to understand this issue - in the article we will talk in detail about the criteria for choosing radiators in a private house and apartment, which are of paramount importance.
Also consider the types of equipment and their features. We give recommendations to customers, supplementing them with visual photos and useful videos.
Types of batteries and their connection
The variety of heating radiators on the market is truly amazing. And it is especially difficult to make the right choice for an unprepared user.
Therefore, in the framework of our article, we will try to consider in detail the varieties of heating devices, paying attention to their key characteristics, and give recommendations on choosing the suitable option based on living conditions, type of heating system and specific requirements of the owner.
Classifications of heating radiators
Heating devices used in the water circuit differ in design, material of manufacture, technical characteristics, design. Next, we will talk in more detail about the types of radiators and their features.
What materials are batteries made of?
As the manufacturing material for heating appliances, most often used:
- steel;
- aluminum;
- cast iron;
- a combination of two metals.
So, steel heating devices can be sectional, panel or tubular. And, depending on the design, their technical characteristics, service life, cost will differ.
The simplest and most inexpensive are panel ones. They withstand a working pressure of up to 10 bar (the value should be found in the passport of the respective model and specific manufacturer), are vulnerable to water hammer, and leaks can occur in places of welds.
Tubular heating devices are more durable - most often their walls are coated with a polymer composition from the inside, which increases wear resistance, allowing to extend the life of the device. They can be sectional or welded.
Aluminum radiators quickly heat up and give off heat to the room, i.e. have low inertness. Due to the large area of the heating surface, they can be used to quickly warm the room.
Cast iron heaters are characterized by high inertness - they warm up for a long time and cool for a long time. This property is rated positively by many users suffering from intermittent blackouts. But, on the other hand, this feature does not allow the use of cast-iron batteries in smart home systems - most models are useless to equip with temperature controllers.
Bimetal is not an alloy, but the correct combination of two metals in one product: the internal elements of the bimetal radiator are made of steel (sometimes copper), and the external (body) of aluminum. Moreover, the steel can be the entire "skeleton" or its individual parts - a pipeline or vertical guides. The first option is better and more expensive.
In more detail, we presented the features of radiators from these types of materials in the following selection of photos.

In addition to the materials discussed above, copper radiators can be found on the market. But the decision to equip the heating system with such devices will cost the owner of a country house a round sum due to their high cost.
Also, copper is susceptible to the quality of the coolant and requires installation skills.
A copper heating battery will harmoniously fit into the autonomous heating system of a country house, where the owner himself can control the quality of the coolant, its heating, etc.
The difference in battery type design
Radiators for the heating system also differ in the type of design and this is noticeable visually.
Structurally, the batteries are:
- sectional;
- panel;
- tubular;
- lamellar.
The most common - sectional. They can be either steel or cast iron, aluminum and bimetal. Due to the ribbed surface, the heating area exceeds the physical dimensions of the product, which positively affects the efficiency of use of devices.
They consist of separate elements interconnected by means of nipple sleeves and gaskets. It is these components that are the weakest point of heating devices of this type. But, if you follow the rules of operation and maintenance of radiators, regularly clean them and change the worn out gaskets in a timely manner, then there will be no leak at the joints, and the product itself will last for many years.
Panel heating appliances - one of the most affordable offers on the market. They are lightweight, easy to install, picky to care for, quickly heat up. But also quickly and cool. Although this property allows them to be used in conjunction with temperature controllers.
Another kind of design - tubular batteries. They are most popular among designers due to the presence of a variety of shapes and sizes. They help to create a unique interior of the room, to zon the room, to bring their own zest.
Towel dryers are a type of tubular radiators. Their design form can be anything, which allows them to completely stand out against the background of plumbing. And users will be warm and comfortable in a spacious bathroom
Tubular radiators are also quite effective, especially since the length and number of sections can be selected to fit your needs.
Least Popular Batteries plate type. Such a device consists of tubes through which the coolant circulates, and plates strung on these pipes. The design provides a large heating area, which allows you to quickly and efficiently heat rooms. But the extremely unpretentious appearance has contributed to the fact that these radiators are used exclusively for heating industrial buildings and common areas.
The design features of the radiators are clearly demonstrated in the next gallery.

Type of device connection
If we talk about the connection, then for heaters for a water heating circuit it can be:
- lateral;
- lower.
Side type of connection assumes that the radiator will be connected to the heating system on the side. For this, manufacturers provide special holes in the product design - on the right or on the left. But some manufacturers do not limit the buyer by making four side holes, and in the manufacture of the battery brackets are not welded to it - then the device can be mounted with either a right or left connection.
Bottom connection involves connecting to the supply line and to the return flow from below. This is convenient if you need to hide the pipes.
You can also conditionally highlight universal option - assumes the presence of six connecting holes in the design of the radiator - two from the bottom and two from each side. The user selects the connection method based on the characteristics of his heating system. The remaining holes are closed with plugs.
The photo shows the bottom battery connection. The supply and return pipes are hidden in the wall, where the gates were specially made at the installation stage
Criteria for choosing the best radiator
When choosing a suitable radiator, a number of nuances have to be taken into account, starting with the type of material and power, and ending with the design. Moreover, sometimes it is the last parameter that is crucial, especially when a designer is involved in decorating a country house.
Due to the demand for original forms and sizes of heating batteries, the modern market can offer interesting solutions. And if necessary, you can order the manufacture of a heater to order. Often, interesting products of complex shape - tubular, made of steel.
The following selection will demonstrate that the battery is an independent piece of furniture, sometimes even its highlight.

A heater can be anything - at least a bench. This simple and functional solution looks stylish and relaxed.
A radiator with a bottom connection, equipped with legs for floor installation, it is quite possible to turn into an elegant bar counter. Why just cover it on top with a tempered glass worktop while maintaining an indent of 10-12 cm
Elegant batteries, 1.5-2 meters long, framed by a tree, imitate a bedside table on which you can place decorative interior items - vases, figurines, souvenirs and others, lovely little things
A device for heating can be a spectacular addition to the interior and certainly will not go unnoticed - a huge drop flowing into the chair. But such a battery will look advantageous in large rooms
Thanks to the intricate shape of the battery, mounted on the wall as a decorative element, it is difficult to recognize the heater in it. But, if you correctly calculate the required power and hang the product by the window, it will be able to fully heat a small room
For rooms of complex configuration, semicircular batteries are well suited. Most often they are made of steel - its characteristics make it possible to give finished products the desired shape. Moreover, designer models of tubular radiators are often cast from steel.
For houses with large windows, it is good to use a thermal curtain. Why use a special type of radiator - floor (built into the floor). They can be used as primary or secondary heating appliances.
The option of placing batteries in the baseboard is also quite popular among private house owners. Why do you need special radiators and a metal baseboard-box, designed for the installation of such convectors. Along with plinth heating, underfloor heating

The ideas discussed above for the original use of batteries in the interior are not limited to this selection. And if you have very simple batteries (still old Soviet ones), do not despair.
They can always be hidden behind a decorative panel or disguised in another way. But in this case, you need to be prepared for heat loss at the level of 5-20% - the exact percentage of heat loss depends on the method of masking, the type of box, its shape and size, the material of manufacture.
Next, we’ll talk about the features and characteristics of devices that are of key importance when choosing a suitable radiator.
Criterion # 1 - fabrication material
When choosing radiators for the production material, it is important first of all to analyze the specific operating conditions.Which will be significantly different for a private house and apartment.
The best radiators for a private home
In private houses there is autonomous heating. And it’s very convenient - the owner does not depend on interruptions and sudden outages of district heating and can control the system’s operating parameters - system pressure, heat carrier quality and its heating temperature.
Therefore, for installation in such systems, you can use steel, aluminum, bimetallic, copper and cast-iron batteries - whatever you like. Moreover, in country houses where designers develop the interior, quite often they use tubular heating appliances of an intricate shape.
Often, it is for private homes and cottages with independent heating that original radiators are bought. With their help, it is possible to transform the room, to bring something original
If the heating system is equipped in a small house, which will be used from time to time, and the owner has allocated a modest budget, then it is quite possible to stop on steel panel batteries - they quickly heat themselves and quickly warm the room.
They also contain quite a bit of coolant, so a lot of time will not be required to fill the system upon arrival and drain the liquid upon departure.
The best solution for an apartment
But in apartments, in most cases, central heating. This means that the owners of such housing can not affect the composition and temperature of the coolant (water with impurities), the pressure in the pipeline, which is higher than in autonomous systems.
And in the case of hydroblows, it rises many times. Therefore, the purchase of panel steel batteries should be immediately abandoned, giving preference to bimetallic. Which are able to withstand a pressure of 20 bar, 50 or more.
By the way, with regard to the specific value of the working pressure, it is indicated in the passport of the device. And it would be nice to immediately ask the seller to look at the test report to make sure that the declared indicators are not embellished, but confirmed by real tests.
Cast iron batteries are also suitable for district heating systems - they are less sensitive to the presence of impurities in the coolant. The only thing required is to periodically disassemble and clean the appliances inside and out
Separately, it is worth mentioning apartments with an autonomous heating system - the conditions are the same as those of owners of a private house. Therefore, it is not necessary to choose practical and expensive bimetallic radiators - with a tight financial situation, it is quite possible to stop on aluminum.
Criterion # 2 - type of radiator and type of connection
As for the choice of the type of design and connection, here you need to take into account specific conditions and your preferences. So, for apartments most often take sectional batteries, picking up the necessary power. But for private homes, any are suitable - panel, tubular and sectional.
In apartments with central heating, there is often no choice in the type of connection - you have to buy batteries based on the location of the riser. Quite often, this is a side right-side or side left-side connection
But in private homes, owners can afford to design the location of risers, pipelines and heating appliances at their discretion.
When choosing radiators, it is important to immediately pay attention to the equipment - whether the accessories are for installation and connection or whether they have to be purchased separately. If you need to buy, then you should definitely pay attention to the diameter (most often 1/2 ”, but there may be another one).
Criterion # 3 - heater power
Also, when choosing batteries, it is necessary to focus on the thermal power of the equipment. Indeed, for a device of an effective heating system, it is necessary to correctly calculate the power of radiators.
If we take the average value for rooms with ceiling heights of up to 2.7 m, then for heating 10 m2, 1 kW will be required. Based on these indicators and calculate the battery power
Before buying, be sure to check which power indicator is indicated in the instrument passport and compare whether it corresponds to the figure noted in the test report.
Many manufacturers do not conduct any tests at all, and enter in the passport any suitable value attractive to potential buyers. Naturally, the products of such firms are best avoided.
Criterion # 4 - heating / cooling rate
The rate of temperature change by radiators is important if the plans include a climate control system. For such purposes, devices with low inertia are suitable - they quickly heat up and cool down.
That allows you to set the desired temperature in the room and control its values by equipping the radiators with temperature regulators.
Bimetallic, aluminum and steel appliances lend themselves well to adjustment. But cast-iron - have great inertness. Therefore, it makes no sense to supplement them with regulators
Criterion # 5 - Manufacturer Reputation
When choosing a radiator, it is better to give preference to trusted brands with a good reputation, among which:
- Steel - Lidea, Conrad, Prado, Charlston, Kermi, Arbonia, Israp Tesi, Buderus PURMO, Delonghi, Korado.
- Aluminum - Global, Rifar, Ferroli, Purmo, Radena, Faral Trio.
- Cast iron - Adarad, Viadrus, Demrad, KIRAN, Konner, Cheboksary Plant and Minsk Plant.
- Bimetallic - Global Style, Sira, Rifar, Tenrad, Halsen, Radena, Rommer.
As you can see, many manufacturers produce more than one type of radiator, which differ in the material of manufacture and other characteristics.
But sometimes it is difficult to distinguish an aluminum radiator from a bimetallic one, the cost of which is much higher. Which can take advantage of an unscrupulous seller. Therefore, before buying, you can conduct a test, for example, with a magnet - a magnet will always be attracted to bimetal.
Another way to check the accuracy of information from the seller is to weigh the radiator section. So, bimetal is always heavier than aluminum - 1.5-2 kg for bimetal versus 0.7-1.5 kg for aluminum
All respectable manufacturers of heating equipment on the market produce marked products that meet the requirements of GOST 31311-2005.
Therefore, if the model you like does not have accompanying documents, there is no marking on the radiator case, then this is a fake or a product of an unknown manufacturer. Buying such a device is a dubious undertaking.
Detailed recommendations for choosing heating appliances:
The test of steel radiators is clearly demonstrated in this video:
Properly selected heating radiators will ensure a comfortable temperature in the cold season. It is important not only to correctly determine the power of heating devices, but also to take into account the type of material - not every radiator is able to withstand the influence of the coolant circulating in the pipeline of a centralized heating system.
Particularly damaging are the impurities contained in the liquid on the walls of aluminum radiators. Therefore, it is better for apartment owners to opt for cast-iron and bimetallic batteries.
And in a private house you can install radiators from any material - the main thing during operation is to follow the recommendations prescribed by the manufacturer in the instructions.
