How to choose radiators?

Types of radiators

There are four main types - cast iron, aluminum, bimetallic and steel. Each of them has its own advantages and disadvantages.

1. Cast iron radiators.

   At one time they were considered the best, but to date there are a number of other technically new products. The reason that this radiator becomes the choice of buyers is first of all, durability, strength and habit. On average, the service life is up to 50 years. In addition, they easily transfer not perfect central heating systems. The fact is that the coolant, which is supplied from the boiler room, often has an aggressive form and is quite dirty. Due to the fact that cast iron is one of the most resistant materials to the action of chemical media, such elements will last long even in poor operating conditions. In addition, the cast-iron radiator withstand pressure differentials. Of the minuses, it should be noted the low thermal conductivity and a large mass, as well as the theoretical brittleness of the metal. Also, the aesthetic part was also attributed to drawbacks - the appearance of such radiators clearly loses to its competitors. However, if you show imagination, then this question can be solved.



2. Aluminum radiators.
   
   One of the obvious advantages is the appearance. But a more powerful argument in his favor is the heat output, which reaches 190W.However, it is not recommended to use it in an apartment with central heating. Due to the high acidity of the feed water, corrosion of the metal in the inner part will very quickly occur. This leads to blockage and disables the heating element. This choice is ideal for a private home. It allows you to adjust the temperature, does not have a lot of weight and has many options.
3. Bimetal radiators.
   
   This kind is great for apartments, as an alternative to aluminum, which in the apartment does not get accustomed. Heat output increases due to aluminum "ribs", and since only the steel tube contacts the heat carrier, such radiators are protected from corrosion. The main advantages of this type:
   • High heat output.
   • Resistant to high pressure for a long time.
   • The main working pressure is 35 atm, which is a very high index.
4. Steel radiators.
   
   This type of radiator is not as actively used as the previous three, but is gaining popularity. The fact is that these products have appeared on the market recently. Its main advantage is a small thickness and a large heat dissipation area, which allows to reduce the amount of heat received and to pay less for heating. At the same time, there are no problems with heating the area. However, the maximum permissible pressure is 8 atm, which is very small. Such radiators can not be mounted in multi-storey buildings.

Based on all of the above, you can much more quickly decide on the question - how to choose radiators for heating?

Thermal power of

In order to confidently choose a radiator, it is also necessary to know the following parameters.
Heating of 1 cubic meter:

• Panel house - 41W.
• Brick house - 34W.
• The house with the use of new thermal insulation means - 20W.

These indicators are designed for houses with plastic windows, in case they stand wooden, then multiply the figures by 15%.Calculate the necessary power simply - you need to know the volume of the room and just multiply by the above data. How to choose radiators for heating is no longer the issue that consumers should be tormenting.
