A huge variety of shapes and materials: how to choose a heating radiator? Types of devices and their features

Preparing for winter involves a lot of different aspects, one of which is correct arrangement of the heating systemTo do this, you need to select the optimal type of radiators.

Installation of the heating system is carried out before the cold weather sets in. To facilitate the selection of the necessary devices, it is necessary understand all their varieties.

Types of heating radiators

Exists several main varieties heating batteries, each of which has its own advantages and disadvantages.

Steel devices

One of the most popular types of heating devices are steel radiators. Most often, they are manufactured not made of steel, but of an alloy of this material, characterized by improved properties and characteristics.

Design specifics steel radiators may vary depending on their model:

1. There are indentations on two steel sheets, made by stamping, circulates through them coolant.
2. Made on steel sheets letter P imprint, inside which heated air circulates air.
3. On the reverse side there are P-shaped ribs, increasing heat transfer.

Thickness The number of sheets used may vary from 1.2 to 2 millimeters. The design of the products is restrained and strict. In order to make the aesthetics of the radiators more attractive, decorative screens can be installed on them.

Pros and cons

Main advantages steel radiators:

• not very significant thermal inertia;
• regulation of battery temperature by means of thermostats;
• good level of heat transfer;
• aesthetics;
• a significant range of products.

As for disadvantages, then them not very many:

• impossibility of installation in an open system;
• lack of compatibility with polypropylene pipes.

Characteristics

Experts highlight the following technical indicators of radiators:

• heat transfer may vary depending on model from 1200 to 1800 Watts;
• working pressure in the range from 6 to 10 atmospheres (as for tubular batteries, they are capable of functioning at higher rates);
• coolant quality plays a significant role, since the inner surface begins to rust as soon as the water disappears from it;
• the coolant temperature can reach 110-120 degrees Celsius;
• height radiators depends on their type - it can be from 20 to 90 centimeters;
• length batteries are limited - no more than 3 meters;
• depth the device reaches 22.5 cm;

In accordance with their technical characteristics, steel radiators, when used correctly, can be quite durable.

Manufacturers

There are many different manufacturers of steel radiators:

• Kermi and Buderus (Germany);
• Israp Tesi (Italy);
• Lidea (Belarus);
• KZTO (Russia).
• KORADO Radik (Czech Republic);

The approximate cost of steel radiators depends on their type and model. The cheapest types can be purchased for 1000 rubles, while the price of the most expensive ones reaches 5000-6000 rubles.

Tubular steel batteries

This type of radiators, such as tubular steel batteries, is a product premium class, which meets most modern requirements. The first such device was created in 1930, after which he constantly improved.

Steel tubular radiators can be made in various forms. All the tubes used in them are connected at the top and bottom by special collectors. This ensures efficient transportation of the coolant in the system.

The level of heat transfer directly depends on the size of the device, as well as the number of tubes in it.

The difference between tubular radiators is that at present for welding their elements a special laser is used. It makes a smooth and almost invisible seam.

Pros and cons

Main advantages steel tubular radiators:

1. Resistance to pressure changes in the heating network. This is achieved through the tubular design.
2. No significant accumulation of dust on the surface of the radiators.
3. Attractive appearance achieved by the presence of streamlined smooth tubes.

5. High-quality welded joints of batteries.

Despite all the advantages, steel tubular radiators also have flaws:

1. Not very high heat output compared to other types of batteries.
2. Susceptibility to corrosion in cases where the coolant is drained from the system during the summer.
3. High cost.

Despite the fact that the price of tubular radiators is high, it pays for itself quickly thanks to long service life.

Characteristics

The particular popularity of tubular steel radiators is due to their characteristics:

• working pressure pipes reach 10 atmospheres;
• thickness the walls of steel pipes correspond 1.5 millimeters;
• height units can be within the range from 30 centimeters to 3 meters;

• Konner (Russia);
• Guratec (Germany);
• Roca (Spain);
• Demir Dokum (Türkiye).

Currently, the cheapest cast iron radiators can be purchased for 600 rubles. They are not distinguished by their designer appearance. Batteries that are more like works of art can cost up to 2000-3000 rubles.

Bimetallic radiators

Various experiments in creating the highest quality radiators led to the production of batteries made from two types of metalsThis ultimately made it possible to use the advantages of both materials.

As a result, such devices have gained significant popularity, since their characteristics are significantly are different for the better from alternative heating sources.

The main difference of the bimetallic type special jumpers available. Manufacturers often use as the main materials steel and aluminum.

The part of the battery that is less susceptible to corrosion comes into contact with the coolant, while those elements that better transfer heat to the premises come into contact with the air.

The inner part of bimetallic radiators usually contains tubes that are connected to flat plates on the outside, which act as a kind of protective screen. Such devices are modern devices in their appearance, suitable for most types of interiors.

Pros and cons

The popularity of bimetallic radiators is due to a number of their positive qualities. The main advantages:

1. Long service life - from 20 to 50 years old.
2. High strength and resistance to fairly strong hydraulic shocks.

4. Resistance to corrosion. This applies even to those cases when a low-quality heat carrier is used.
5. Beautiful appearance, allowing them to be used even in rooms with a modern design.

As for disadvantages, then they are in bimetallic radiators not very much:

1. Relatively high cost, which exceeds the price of other batteries several times.
2. Some models may be susceptible to rust (but this is rather an exception to the general rule).

Thus, a large number of positive qualities of using bimetallic radiators made these devices some of the most popular last time.

Characteristics

Main technical characteristics of bimetallic radiators:

• heat transfer level is within the limits from 170 to 190 W;
