When choosing radiators for the home should take into account not only their appearance and power, but also the material, from which they are made. modern battery, usually, made of steel, but the market can also be found aluminum and cast-iron solutions. Below their features, which will help to choose the right radiator.
steel radiators
radiators, steel имеют высокую популярность благодаря их большому разнообразию. Among them are the most popular ones, are used a lamellar structure. So, powerful battery with compact dimensions, It should have a large number of plates. This is especially important, If the wall is no space for a large heatsink.
In addition to better protection against corrosion, steel heaters sensitive to the quality of water. Strength of steel radiators reduced, if at the time of their installation in the oxygen enters the system. Therefore, it is better not to use in open systems (using solid fuel boilers), as it allows air to get inside.
Cast iron radiators
Cast iron radiators are not popular. Usually, they can be found in older homes. On the other hand, they have a high resistance to corrosion - durability of cast iron radiators is measured in decades.
For this reason, more advantageous to use a cast iron radiators in older heating systems. They can come not like, but they have a lot of advantages. So, in batteries of iron better resistance to corrosion, that allows them to operate for several decades. The quality of water in this case does not play a role. Also, cast iron radiators have good thermal inertia. They must be long enough to heat, but on the other hand, they are too slow cool.
Unfortunately, with them it is impossible to quickly change the temperature, but it has a positive effect on the operation of the boiler, because it is not necessary to frequently and rapidly burn. In the long term operating conditions it allows you to save. High inertia cast iron radiators - an advantage for solid fuel boilers, as they will be warm for a long time, even after the fire burns.
aluminum radiators
Aluminum radiators are less popular, than steel. Similarly, the last, they also have a lamellar structure. Aluminum radiators have a low weight and have low thermal inertia. Therefore, they are best used in modern boilers on liquid fuel, equipped with automatic temperature control.
