Aluminum heating radiators are produced by casting and the corresponding alloys. Thanks to this production process, it is possible to provide them with such necessary properties as high heat transfer and lightness. At the moment, aluminum heating radiators are the most acceptable and warm of all that are on sale. They consist of sections, which are vertical elements that can be assembled in any quantity, depending on the needs.
The front surface of the sections is perfectly flat due to the use of a special multi-layer coating. Aluminum radiators are painted quite high quality, so they look much better than steel and cast iron. However, it all depends on the taste of the consumer. The side and back surfaces are usually painted with a slightly thinner layer, and casting in these places is not as accurate as the front. This is due to the desire of the manufacturer to reduce the cost of production.
Aluminum heating radiators : specifications
One structural section has two horizontal directional collectors that are connected by means of vertical tubes. The front panel radiates heat, and here to increase heat transfer the section is equipped with vertical plates that form channels that heat the air. At the bottom of the section there is a recess, it is intended for sedimentation of dirt. Recently, cutouts have begun to be made on the back side, simplifying the installation process, and also allowing to significantly save metal.
Distinctive characteristics of this type of radiator are high heat transfer and low weight, as already mentioned. This type of equipment is quite convenient to use for
heating private homes.But aluminum heating radiators also have negative properties, which you should also be aware of before using them. The reason is the material from which they are made. In the heating system, water reacts with aluminum, resulting in an increase in pressure due to significant gas formation. Such a radiator cannot be cut off from the system if it is filled with water, since there will be nowhere for gases to escape, which can lead to rather dire consequences. If the radiator is not cut off from the system, excess gases pass into the boiler equipment, where they are neutralized. Some experts recommend the installation of aluminum heating radiators using on each of them special air vent valves operating in automatic mode.
Another very important point associated with the use of this type of equipment is its combination with copper pipes. It is believed that this causes accelerated corrosion. However, in practice this does not happen. This restriction is not indicated in the instructions for the boilers, nor in the instructions for radiators. It turns out that their use in any system is perfectly acceptable.
