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.

Two stages of production of bimetallic radiators

Stage one is the production of a steel core through which the coolant will subsequently flow. The core must be entirely welded, without a single crack - water or antifreeze must not get beyond it, onto the aluminum jacket. The steel manifold is filled with molten aluminum and silicon under high pressure.

The final stage in the production of a bimetal radiator is painting . For this purpose, special powder paints are used. The painting method is electrostatic. Radiators are also painted in 2 stages: first, the finished equipment is lowered into a bath for anaphoretic painting, then coated with powder enamel. Throughout their entire service life, bimetallic equipment does not require additional painting; they retain their appearance perfectly.

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.

Technical characteristics of bimetallic batteries: what to look for

When choosing bimetallic batteries for home or office heating systems, you should definitely pay attention to the technical parameters of such products.

Often, such qualities are indicated as follows:

Heat dissipation - the manufacturer denotes it in watts, shows how much heat the batteries can give off when the coolant passes through;
Working pressure - as a rule, bimetallic radiators are characterized by a pressure of 16-35 atm. Moreover, in autonomous heating systems this figure reaches 10 atm, and in centralized heating systems – up to 14 atm. In most cases, the manufacturer provides a sufficient safety margin for the normal operation of radiators in heating systems of various types;

Bimetallic radiators in various heating systems

Center distance . This parameter refers to the distance between the lower and upper collectors of the battery. The parameter is indicated in millimeters and is often standardized - 200, 300, 350, 500 or 800 mm;

Tip: When choosing the overall dimensions of radiators, you should be sure to maintain fifteen-centimeter clearances from the floor and window. Only in this case it is possible to ensure compliance with the existing requirements of fire safety standards and a good level of heating.

Maximum temperature of the coolant used . Most bimetallic heating devices are characterized by a parameter of 90C. When choosing bimetallic heating radiators, you must take into account the factor in order to achieve high heat transfer rates.

How do bimetallic heating radiators work?

The design of bimetallic radiators is clearly hinted at by their name - bimetallic, which means - consisting of two metals. The internal part of the radiator, through which the coolant flows, is made of steel (copper) pipes, and the external part, which serves to transfer heat to the surrounding air, is made of aluminum.

The advantages of this design are obvious. Steel pipes can easily withstand high pressure in the heating system; in addition, unlike aluminum pipes, they are chemically resistant to various harmful impurities that may be contained in the coolant. And the aluminum body has the best heat transfer rates compared to other materials. This has a beneficial effect on the dimensions, weight and appearance of bimetallic radiators, and also makes them very responsive to signals from temperature control equipment.

Bimetallic heating radiators, the core of which is made of copper, have the best characteristics, but their prices cannot be called affordable. Copper-aluminum radiators are recommended for installation in a system with a gas boiler with a copper heat exchanger. For boilers with steel heat exchangers, aluminum-steel bimetallic radiators are suitable.

A bimetallic radiator is a set of sections connected to each other by means of a threaded connection. Each section contains a pair of steel pipes - upper and lower, which are connected by a jumper. Using a special injection molding technique, an aluminum housing is tightly attached to the outer surface of the steel pipes, performing the functions of a heat exchanger. For maximum heat transfer to the surrounding air, the aluminum heat exchanger has a complex shape with numerous channels for better convection.

In addition to purely bimetallic radiators, “semi-bimetallic” ones are also produced, in which the core is made of steel only partially - its vertical channels are steel, and its horizontal channels are aluminum. The price of such radiators is about 20% lower than the price of batteries with all-steel pipes, but they are less durable, since there is a risk of leaks at the junction of the two metals in the core. Heating systems of multi-storey buildings are characterized by high operating pressure, as well as low quality coolant, so it is better to use bimetallic batteries with all-steel pipes.

The best models with bottom connection

Radiators with bottom connections make it possible to hide pipes and fasteners . Let's consider the best models with this characteristic.

The coating does not scratch and looks new even after several years of use.

Battery sizes

The dimensions of the device are important, since with the required power parameters it must fit in a niche under the window. What sizes can bimetallic batteries have?

Bimetallic heating radiators are characterized by standard height dimensions. The device has a marking that indicates the center distance of the device - 200, 350 or 500 mm.

Important! When choosing a radiator, it is necessary to take into account that the center distance is the gap between the inlet and outlet holes of the battery, which does not correspond to the entire height of the case. To find out the actual height of the device, you need to add 80 mm to the center distance.

Full height of the device with different markings:

marking 200 – actual height 280 mm;
350 – device height 430 mm;
500 – height 580 mm.

USEFUL INFORMATION: Adhesive for linoleum cold welding, price

The width of the heating device will depend on the number of sections, which is calculated based on the parameters of the room and the power of the individual section.

Attention! When choosing the size of the radiator, do not forget that, in accordance with technical standards, the device must be installed at a distance of at least 10 cm from the window sill and 6 cm from the floor.
