In order to ensure a comfortable life in a private house or apartment, one of the main roles is played by heating radiators, which of them will help you better understand each type and type available today. The radiator itself, as part of the housing, must meet the following requirements:

  1. It should not stand out clearly against the background of the interior.
  2. Must effectively fulfill its direct purpose.
  3. Must be durable and reliable.
  4. Must have good thermal conductivity and storage properties.

Unfortunately, all of the above properties are not inherent in a single type of heating battery, which is the best of them we will understand in the course of the review.

Today there are at least 4 types of radiators for building a liquid heating system, each type has its advantages and disadvantages. Yes, a person has not yet developed an ideal option that would meet all the requirements.

Types of radiators:

  1. extrusion;
  2. casting.

The first method is a method of extruding an aluminum alloy into a mold. The product thus does not have channels, and individual vertical parts are pressed onto a collector completely made of silumin. Such radiators are cheaper in production, but their productivity is lower than that of the second method. But they have the advantage of reliability. radiators for heating

The second method is a high pressure die casting. Each section has a transverse channel connecting the upper and lower ducts, and the walls are made thickened. The material is a mixture of aluminum and 12% silicon, which gives the individual section the necessary strength and can withstand pressures up to 10 atmospheres.

The advantage of this method is that the casting is continuous. As a result, the heat transfer is higher, but compared to the next type, they are less durable because of the susceptibility to corrosion and chemical reactions. It is important to remember that when designing a heating system using aluminum radiators, do not use steel and brass connecting elements. Only plastic pipes and brazed fittings should be used as connectors. This is due not only to corrosion due to the use of different metals, but also the occurrence of surface currents. Because of this, the system with aluminum radiators must be reliably grounded.

Casting can also be of two types. It was the first. The second one is the same aluminum, only after processing by anodic oxidation. It allows you to slightly change the crystal lattice of metal, which makes it invulnerable to corrosion and more durable. They are able to withstand working pressures of 50 to 70 atmospheres. At the same time, the fracture pressure can reach more than 200.

Anodized aluminum radiators have smoother internal walls, which promotes better circulation of the coolant, giving away more heat. And a huge limit of working pressures makes it possible to use it for heating systems in multi-apartment buildings.

radiators Bimetallic

  • aluminum;
  • bimetallic;
  • steel;
  • cast iron.

All these types of radiators, photos of which are in front of you, today have good performance, because they use modern and accurate equipment.

Different aluminum radiators for heating are available for sale, which ones are better to use, now we will understand. So, this type is a sectional product made of aluminum by injection molding. Such a radiator has high heat output, which affects its instantaneous heating. This is due to the physical properties of aluminum itself. It is faster than all other metals, of course, except for copper used for the production of heating systems, it heats up and cools. Heating systems built on their basis are most often used for private construction. In multi-storey houses they are not recommended for use because of high pressure in the central heating system. The working pressure of aluminum radiators is about 10 atmospheres. And in multi-storey houses it varies from 10 atmospheres and above.

In a private house, different kinds of heating batteries can be used, because the system is controlled autonomously, and on each radiator it is recommended to install a thermostat. Before answering the question of how to choose aluminum radiators, you should familiarize yourself with the types of their production:

Bimetallic heating radiators are one of the types of aluminum, but they are arranged a little differently. Inside there is a steel smooth-walled pipe, and around it there is an aluminum shell that pours into the mold. Today on sale there are different radiators bimetallic, which is better of them, now we will understand.

The market can be found as a combination of two metals from aluminum to steel, and aluminum plates with copper. The second type is called cellular. And, of course, he is both better in terms of heat transfer properties and conversion than all of the above. But the cost of such a radiator will also be very high.

The advantages of bimetallic radiators include, first of all, a high working pressure of about 25 atmospheres and a limiting pressure test of 35 atmospheres. This enables them to be widely used in multi-storey construction( up to 25) for heating apartment buildings. But because of the combination of the two metals, they have less thermal conductivity, which affects the performance.

In the market there are different sizes of bi-metal batteries, which are better to choose, depends on the required performance and placement. On average, on 1 m2, 50 to 120 W are required. With better insulation and fewer windows, you can choose fewer sections, with less quality, more. The height of the ribs depends on the installation site, but with a 2-fold decrease in height, the number of sections must be doubled.

We examined different aluminum heating batteries, which is better, reviews can be read on a variety of resources and in the online stores from buyers. But it is also possible to compile all these batteries in order of decreasing efficiency:

  1. bimetallic with copper central tube( honeycomb);
  2. anodized aluminum;
  3. aluminum;
  4. bimetallic with steel pipe.

All available commercially available aluminum batteries have been described, which are more obvious. The latter type is anodized. They are more durable, durable and the most expensive, because they are more difficult to produce.

Choosing the brand

Choosing aluminum radiators for your home, what better manufacturers need to know, because this also determines their service life. Today there are many companies supplying these products, but the most common are the Italian brands FERROLY, SIRA and Global. Radiators from these brands can withstand working pressures up to 20 atmospheres. Among Russian manufacturers, mono company RIFAR.Its products can withstand pressures of up to 20 atmospheres and are a complete copy of the Italian brand Global.

Steel

Steel radiators are a structure of two profile sheets of steel coated with polymer paint, and a system of steel pipes connected in parallel. On sale there are a variety of sizes and performance of steel radiators, which depends on the quality of its performance and size. They are on sale at least 4 form factors, both in height and width. Therefore, they are the most widespread. In addition, they cost much less than previously described. Because of their shape they also have the name of panel radiators, which are best used for a private house, depends on the area of ​​the heated room and the interior. After all, they can be different coloring.

The advantage of steel radiators is the possibility of heating the coolant up to 1100C at an operating pressure of up to 10 atmospheres. Produced as panel radiators, and tubular. The second can withstand the pressure up to 15 atmospheres, but it is not enough for use in the central heating system in multi-apartment buildings.

The most common manufacturers of steel radiators are:

  • German companies Buderus and Kermi;
  • Czech - Korado;
  • Finnish - PURMO.

The products of all manufacturers have the same working pressure parameters, which is about 10 atmospheres and is a honeycomb structure.

Cast-iron

Cast-iron radiator on the legs

Cast iron batteries are all well-known types of radiators. They have good indicators of heat accumulation, but less heat loss due to their powdery structure. Cast iron slowly heats up and also slowly cools. Today they are still sold in our market and, being a standard, are actively installed in multi-apartment buildings up to 15 floors. They are no longer suitable, because the pressure should be higher than this indicator. Among the model range are represented a variety of shapes and shapes. Suspended and standing on legs, rounded and rectangular. Whatever the cast-iron radiators are, which are the best ones to choose? The question is not relevant, because productivity in all types is the same and does not depend on the form.

For multi-apartment, more than 15 floors, the construction of aluminum radiators as well as cast iron is not recommended. Because with the hydraulic attacks, which are created when the system is turned on, they can burst. The best options are bimetallic famous brands or anodized. The latter have excellent parameters for both thermal conductivity and reliability.
