What is a bimetal radiator? Reviews, specifications, parameters, their arrangement - this article will tell about everything. Based on these specifications, you can choose exactly the device that best suits you and allow you to get the best result at the lowest cost. Such heating elements harmoniously combine the advantages of steel and aluminum batteries (from the combination of these two materials and their name takes place). They have the same high strength as the first, and heat transfer - like the second.
Characteristics
The first important parameter is the interaxial distance between the pipes. According to this criterion, they are of two types - 350 mm and 500 mm. If possible, large models are installed, otherwise small ones. The second important characteristic is the working pressure. The most common devices are with the following values:
- 16 bar (Chinese products);
- 18 bar (Ukrainian or Russian products);
- 24 bars (batteries from Germany);
- 34 bars (heating elements from Italy of increased quality).
The best are the last bimetallic radiators. Reviews about them are only positive. The thermal power of each section can vary from 100 to 200 watts. The higher the value of this parameter, the better the energy efficiency of the device. The volume of water that is inside them varies from 0,15 to 0,38 liters. The lower this value, the lower the fuel consumption, and hence the cost of heating the housing. The operating temperature ranges from 110-130 degrees Celsius. Experience shows that even the minimum figures of the scale are quite enough for high-quality heating of the dwelling. In general, this value is chosen depending on the maximum operating temperature of the boiler unit. These characteristics most accurately determine the bimetal radiators. Reviews also play a role in this. But we'll talk about this a little later.
How to choose?
Now we will find out how it is better to choose bimetal radiators. Reviews - this is the first component. The words of the people using these heating devices should be mostly positive, and they should be as much as possible. Next, you need to pay attention to the boiler. The pressure at its outlet and the maximum flow temperature should be less than the maximum permissible for the radiator. The overall dimensions are chosen depending on the possibility of installation. If the area allows you to put a large battery, it will be better, because the more its surface, the better the heat transfer. Well, if you can not choose a large device for heating the housing, then you can mount a compact version. The last criterion, which should pay attention to the selection stage, is how much the bimetal radiators cost. Prices can vary from $ 10 per section (cheap Chinese products) to 20 or more (quality products from Europe).
conclusions
The best bimetal radiators should withstand high pressures (up to 35 bar), have different center distances (both 350 mm and 500 mm). The maximum operating temperature should be at least 110 degrees Celsius. It is also important to understand that the products of world famous brands comply with the declared specifications and are highly reliable. In turn, products of Chinese production can not always boast a high level of quality. It is important to remember this at the selection stage and take it into account before buying.
