In ensuring a comfortable life in a private home or apartment is one of the main roles played by radiators, what is the best of them will help to understand introduction to each type and views, available on the market today. I already radiator, as part of the housing, must meet the following requirements:
- It should not be explicitly allocated for interior background.
- Must effectively fulfill its intended purpose.
- Must be a durable and reliable.
- Must have good thermal conductivity and accumulating properties.
TO, Sorry, all of the above properties are not inherent in the same type radiators, what is the best of them will understand the course of the review.
Today, commercially available for at least 4 radiators species for constructing liquid heating system, each type has its own advantages and disadvantages. Yes, the person has not yet developed an ideal option, which would meet all the requirements.
Types of radiators:
The first method is a method of extrusion into a mold of aluminum alloy. The product thus has channels, and some vertical portions are pressed to the collector, completely made of silumin. These radiators are cheaper in production, but also the performance of their lower, than the second method. But they have the advantage of reliability.
The second method is a molding in high pressure form. Each section has a transverse channel, connecting the upper and lower ducts, and performed thickened wall. The material is a mixture of aluminum and 12% silicon, giving separate sections necessary strength and capable of withstanding pressures up to 10 atmospheres.
The advantage of this method is that, that continuous casting is satisfied. Whereby the above heat transfer, but compared with the following type are less durable because of exposure to corrosion and chemical reactions. Important to remember, that the design of the heating system with the use of aluminum radiators should not be used joints of steel and brass. As the connectors must be used only plastic tubes and soldered fittings. This is due not only to the corrosion due to the use of different metals, but also the occurrence of surface current. Because of this system with aluminum radiators must be securely grounded.
Molding can also be of two types. It was the first. The second represents the same aluminum, Only after the anodic oxidation treatment. It allows you to change a little the metal lattice, which makes it immune to corrosion and more durable. They are able to withstand the operating pressure 50 – 70 atmospheres. When this fracture pressure can reach more 200.
Radiators made of anodized aluminum have a smooth inner wall, which promotes better circulation of coolant, thus giving more heat. A huge limit on working pressure can be used for heating systems in apartment buildings.
- cast iron.
All of these types of radiators, photos that before you, today have good performance, because it applies a modern and precise equipment in their production.
On sale are available different aluminum radiators, What better use of them, Now we shall understand. so, This type of product is a sectional, made of aluminum casting in the mold. Such a heat sink has high heat transfer figures, that affects its instantaneous heating. This is due to the physical properties of the aluminum. It is faster than all other metals, of course, in addition to copper, used for the production of heating, heats and cools. Heating systems, based on them, It is most often used for residential buildings. In multi-storey buildings their use is not recommended because of high pressure in the central heating system,. Operating pressure reaches about aluminum radiators 10 atmospheres. A multi-storey buildings varies from it 10 atmospheres and higher.
In the private house of the different types of radiators can be used, because the system is controlled independently, and on each radiator is recommended to set the thermostat. before, than to answer the question, how to choose aluminum radiators, should be familiar with the types of production:
Bimetallic heating radiators are one of the types of aluminum, but arranged slightly differently. Inside there is a steel smooth pipe, and round aluminum shell, which is poured into the mold. Today on sale there are different radiators Bimetallic, what is the best of them, Now we shall understand.
On the market can be seen as a combination of two metals of aluminum and steel, and aluminum plates with copper. The second type is called a cell. AND, of course, it is both the heat transfer properties, and better conversion, than all of the above. But the cost of such a radiator is also great.
The advantages of bimetallic radiator relates primarily high operating pressure of the order 25 atmospheres and limit crimping - 35 atmospheres. This enables them to be widely used in high-rise building (to 25) for heating of houses. However, due to a combination of two metals, they have a lower thermal conductivity, which affects the performance.
In the market there are different size bimetallic battery, What is better to choose, It depends on the desired performance from her and placements. On average, 1 m2 required from 50 to 120 W. When higher quality and fewer insulation of windows may be selected minimal number of sections, at least qualitatively - more. The height of the ribs depends on the installation location, but with a decrease in height 2 fold, must be twice the number of sections increase.
We have considered various aluminum radiators, which is better, reviews can be read on a variety of resources and within online stores from buyers. But it is also possible to make these batteries in decreasing order of efficiency:
- Bimetallic copper core pipe (cell);
- anodized aluminum;
- bimetal with steel pipe.
all commercially available aluminum radiators have been described, which is obviously better. The latter type of, anodized. They are more durable, durable and most expensive, because they are more difficult to produce.
Choosing for your home aluminum radiators, which is best producers need to need to know, because it affects their life. Today there are many companies, supplying these products, but the most common are the Italian brand FERROLY, CHEESE and Global. Radiators of these brands can withstand working pressures of up 20 atmospheres. Mono among Russian producers to allocate company RIFAR. Its products can withstand the pressure and to 20 atmospheres and are a full copy of the Italian brand Global.
Steel radiators constitute a structure of two profiled steel sheets, coated with a polymeric paint, system steel pipe and, paralleled. On sale are very different in size and performance of steel radiators, which is best depends on the quality of its performance and size. They are commercially available for at least 4 form-factor as the height, and width. Therefore, they are most widely. Besides, they cost a lot less, than previously described. Because of their shape they are also called panel radiators, what better one to use for private house, It depends on the area of heated space and interior. After all, they can be of different color colorings.
An advantage is the possibility of steel radiators coolant heating to 1100C at an operating pressure of up to 10 atmospheres. Available as panel radiators, and tube. Second thus can withstand pressures up to 15 atmospheres, but it is not enough to be used in central heating systems in apartment buildings.
The most common are the manufacturers of steel radiators:
- German companies and Buderus Kermi;
- Czech - Korado;
- Finnish - PURMO.
Production of all producers have the same parameters of the working pressure, which is about 10 atmospheres and presents a honeycomb structure.
Cast-iron batteries are all well-known types of radiators. They have good performance of heat accumulation, but at heat dissipation because of its powder structure. Iron slowest heats up and cools down as slowly. Today, they continue to sell in our market, and, It is the standard, actively installed in apartment houses to 15 floors. More than they already do not work, because the pressure needs to be higher than that. Among the lineup are a variety of shapes and figures. Mounted and standing on legs, round and square. Whatever the cast iron radiators, what better one to choose? The issue is not relevant, because all types of performance is the same and does not depend on the form of.
when an apartment, more 15 floors, building use of aluminum radiators as iron is not recommended. Because when hydroblows, which are created when the system is turned on, they can burst. The best option would be bi-known brands or anodised. The latter have different parameters such as thermal conductivity, and Reliability.

I had to change one of the batteries in the room five-story building. At all, throughout the apartment are iron battery, look, of course, not as aesthetically pleasing as the modern, but the heat well. The main advantage of cast iron batteries they hold heat, will explain, if the house has lowered heating or in case of emergency shut off, iron will cool down slower than modern counterparts. Necessary to replace, we have made in favor of the aluminum radiator, consultation in stores, sellers were advised Bimetallic, claimed, aluminum battery that is suitable for an individual way of heating, a central heating implies greater pressure can deform and aluminum. However, most friends and acquaintances claimed, that their apartments are a battery of aluminum and there is no problem. To date, the battery is made of aluminum is already the 2nd heating season and had no problems with her work does not arise.
It's not about pressure, and corrosion due to aggressive media
If aluminum is the risk of a galvanic couple with other. a central heating system components.
This problem is solved by correct selection of materials.
