Top manufacturers of bimetallic radiators

The most popular radiators are produced by European companies. But domestic equipment is not inferior in quality thanks to the use of innovative technologies in production.

Stay up to date! The best brands of bimetallic radiators:

Royal Thermo. One of the largest manufacturers. It uses European systems, the entire cycle is subject to multi-stage quality control. The products have a wide range.
Global. A domestic manufacturer that produces radiators fully adapted to the local climate. The structures are easy to install and connect to any heating systems.
Sira. Products of an Italian company. It is considered the standard of modern design and quality.
Rifar. A Russian brand that produces radiators adapted to Russian operating conditions. The products come in a variety of designs.

How many sections will be needed?

To determine the required number of sections for a specific area, you should first look at the technical data sheet of the radiator. This document contains information about the thermal power of each section, expressed in watts, which will be needed to calculate their number. The required volume of heat generated by radiators depends on the characteristics of the heated area. Let's look at common options.

USEFUL INFORMATION: Types of batteries: choosing a heating radiator for an apartment

Room parameters	Required power for heating 1 sq. m area
One window, one wall facing the street, ceiling height – 250–270 cm	100 W
One window, two external walls, similar height	120 W
Two walls to the street and two windows	130 W

How is the calculation made?

Calculating the required number of sections is simple.

To obtain the required thermal power of radiators for a room, we multiply the area by the heating power indicator determined from the table above. If the apartment has unusually high ceilings or panoramic windows, then a correction is applied and the result is additionally multiplied by 1.1.
The power value for a separate section is taken from the bimetallic radiator passport. Then the result obtained in step 1 is divided by the figure taken from the instructions for the device. This way you get the required number of sections for the room. Non-integer values are rounded up. The same is done with the number of sections, since often the radiator consists of an even number of them.

Calculation example

To speed up the operation of counting sections, use the following formula:

Ks = P × Mk / Ms

Ks – number of sections;
P – area of the heated room;
Mk – power required to heat 1 sq. m;
Ms – thermal power of one section.

For high ceilings or large windows, the resulting Kc value is multiplied by a correction factor of 1.1.

For example, you need to install a bimetallic radiator in a room of 20 square meters of standard height with two walls facing the street and one panoramic window. Using the formula, we calculate: 20 sq. m multiplied by the required heating power of 120 W and multiplied by 1.1. We divide the result by the power of one section, for example, 200 W.

What characteristics should you pay attention to when choosing a bimetallic radiator?

Keep in mind! When choosing a bimetallic radiator, you need to pay special attention to the following parameters:

Brand. Reliable manufacturers provide a guarantee for their products for up to 25 years. This will help to replace the radiator, even if it fails after 10-15 years.
Heated area. How many sections should be purchased depends on the square footage of the room. For an accurate calculation, you need to know the power of the unit.
Price. In this case, it is better to give preference to the “golden mean”. You also need to take into account the number of sections. The convenient thing is that you can buy not a ready-made kit, but section by section.

How to choose and what to pay attention to?

Bimetallic radiators are usually installed in multi-storey buildings, where the pressure in the heating system is high, and lightweight aluminum devices simply cannot withstand it.

Despite the fact that all bimetallic radiators have similar performance characteristics, when choosing, you should be guided by several parameters:

Power . On average, it ranges from 160-2400 W. The higher the power, the faster the radiator sections will warm up and it will begin to give off heat.
Number of sections . This criterion directly depends on the area of the room. The larger the room, the more sections the radiator should have. Otherwise, the device simply will not be able to properly warm the room. For small rooms (for example, a bathroom), there is no point in buying a radiator with a large number of sections, as this will make the room too hot.
Pipe diameter . It must match the diameter of the pipes of the heating system itself. It is also desirable that the pipes, if necessary, can be easily replaced.

USEFUL INFORMATION: How to install a temperature controller on a battery

The monolithic design has improved performance characteristics: it can withstand significantly higher coolant pressure, easily withstand even the most powerful water hammer and have a service life of 100 years. Leaks between blocks that are possible with sectional radiators are also eliminated. The described qualities are achieved due to a solid steel core, which has no weak points in the form of docking nipples.

Steel or bimetallic – what to choose?

Steel radiators are not suitable for installation in apartment buildings. They are distinguished by their attractive appearance and resistance to corrosion, but are very sensitive to pressure. Working pressure ranges from 6-16 atmospheres.

Frequent water hammer in the system will damage the radiator and it will begin to leak.

Taking these features into account, steel radiators are recommended to be installed in private houses or apartments with autonomous heating.

In all other cases, it is better to give preference to the bimetallic model.

Cast iron or bimetallic – which one to choose?

In the past, cast iron batteries were considered the only possible option for heating apartments and houses.

But now they are losing to bimetallic devices in almost all respects.

Firstly, such devices are very heavy, so it is unlikely that you will be able to install them yourself.

Secondly, these radiators can hardly be called attractive in appearance, although there are expensive designer products on the market, decorated with forged elements.

But at the same time, cast iron batteries are distinguished by a very long service life, the ability to withstand severe pressure changes and resistance to corrosion.

But, in comparison with bimetallic devices, cast iron batteries lose in terms of thermal conductivity.

They take a very long time to reach temperature, so it takes a lot of time to warm up the room.

In addition, they do not have a regulator, and the user will not be able to independently set the desired temperature in the room.

Global STYLE PLUS 500

This model, produced in Italy, has received many rave reviews. Manufacturers use alloy steel for the inside of the battery, and aluminum alloy for the outer coating. The advantages of a radiator include the following criteria:

high strength;
good heat dissipation;
the ability to complete batteries from 4 to 14 sections;
resistance to aggressive coolants;
high resistance to temperature changes;
maximum working pressure (35 atm.).

As the temperature decreases, the heat transfer decreases slightly. This indicator can be attributed to a lack of equipment.

Prices: 685 – 13800 rub. depending on the number of sections and characteristics of the radiator.

“I couldn’t even imagine that the radiator would generate so much heat in the room. I purchased a Global Style 500 bimetallic battery. It has been working properly for 4 years, and the house has become much warmer. I haven’t regretted my purchase for a minute.” Eleonora, Moscow
