Radiators made of aluminum and bimetal are currently the leaders among heating devices. The first ones are the most popular, which is associated with a high level of heat transfer and a low price tag. Many manufacturers produce similar products in different price segments. Sellers are trying to sell what is more expensive and just sell as much of their product as possible.
As a result, a person who has no experience begins to get lost and does not understand what to buy: what is more expensive or what is cheaper. After all, the appearance and characteristics of various products are almost the same.
What we are recommended to pay attention to
As a rule, there are several points that many sellers advise to pay attention to (what to take and what to refuse):
- Chinese products are of poor quality, which means it is better not to consider them;
- the heavier the product, the better it is;
- the larger the width and thickness of the device, the better;
- the more expensive, the higher the quality;
- material strength.
And here it is necessary to consider in more detail each of the statements.
1. Russia or China - what to take
For some reason, modern society has a stereotype that low-grade products are made in China. This statement does not correspond to reality. Both in our country and in China, they can produce both disgusting products and really high-quality equipment.
2. The more weight, the better the device
In this case, one cannot but agree. Theoretically, such a product has thicker walls, which means that the service life should be longer. In reality, this is not yet an indicator of a high-quality radiator.
3. The larger the heatsink, the better
The situation is similar to the previous one (meaning weight). If theoretically it can be considered that this is really more reliable and more durable, then in reality the situation is somewhat different, especially if the equipment is installed in a private house. That is, this indicator is not fundamental here at all.
4. The higher the cost, the better the device
For the most part, it really is. But there is no absolute guarantee that the price will match the quality. In pricing, a lot depends not only on the characteristics and quality indicators, but also on the desire of the manufacturer, and then the seller, to make money.
5. Strength
Any aluminum radiator cannot be called too strong, resistant to damage. Yes, among the devices there are more or less durable, but it depends directly on the alloy.
6. The most important
Any devices made of aluminum would be more correctly called silumin. Silumin is an alloy containing, in addition to aluminum, silicon (there are other compounds, but they are not so significant). The presence of silicon provides increased strength to the product, and hence a longer service life. But there is a second point worth paying attention to - the less silicon in the alloy, the higher the heat transfer and, accordingly, the cost. And the main thing for us is that the heat transfer is as high as possible.

And the last ...
Choosing a radiator with increased heat transfer, it should be understood that automatically its dimensions, like its weight, will be quite large. Therefore, the first thing you should look at in a store is the alloy itself and heat transfer, and only then everything else.
It will be no less interesting and useful to find out why do professional masters install radiators at a slight slope.
