How to choose the radiators ?

radiators

Types There are four main types - cast iron, aluminum, steel and bimetal.Each has its advantages and disadvantages.

1. Cast iron radiators.

   At one time they were considered the best, but to date there are a number of other technical new products.The reason that this is the radiator becoming the choice of buyers - is first and foremost, durability, strength and habit.The average service life up to 50 years.In addition, they are easy to carry not committed a central heating system.The fact that the coolant which is supplied to the boiler, is often sufficiently aggressive form and contaminated.Due to the fact that iron is one of the most sustainable materials to chemical environments, such elements will last a long time even in bad conditions.In addition, the cast iron radiator with dignity withstand pressure differentials.Of the minuses should be noted a low thermal conductivity and a large mass, as well as the theoretical fragility of the metal.Also attributed to the shortcomings and aesthetic part - the appearance of such radiators is clearly losing its competitors.However, if you show imagination, and then the matter can be resolved.



2. aluminum radiators.
   
   One of the obvious advantages - it's appearance.But a strong argument in its favor - a thermal capacity which comes to 190Vt.However, it is not recommended to use it in an apartment with central heating.Due to the high acidity of the water supplied metal corrosion occurs very quickly in the inner part.This leads to blockage of the heating element, and outputs from the system.This choice is ideal for private homes.It allows you to adjust the temperature, it does not have much weight and has many variants.
3. Bimetallic radiators.
   
   This type is great for apartments as an alternative to aluminum, which does not take root apartment.Heat transfer is increased by aluminum "ribs", as well as a coolant in contact with only a steel pipe, radiators are protected against corrosion.The main advantages of this type:
   • High rates on heat transfer.
   • resistant to high pressure for a long time.
   • main operating pressure is 35atm that is very high.
4. Steel radiators.
   
   This type of radiator is not as widely used as the previous three, but is gaining in popularity.The fact that these products have recently appeared on the market.Its main advantage - it's a small thickness and a large heat transfer area, which allows to reduce the amount of heat produced, and pay less for heating.This problem is not with the heating area.However, the maximum allowable pressure - 8atm, which is very little.These radiators must not be installed in high-rise buildings.

Based on the above, we can more quickly determine the question - how to choose the radiators?

Thermal power

order to confidently choose a heating radiator, you must also be aware of the following indicators.
heating 1 cubic meter:

• Panel house - 41Vt.
• Brick House - 34W.
• House with new thermal insulation means - 20W.

These indicators are designed to house with plastic windows, if the cost of wood, the figures should be multiplied by 15%.Calculate the power required is simple - you need to know the amount of space and just multiply by the data presented above.How to Choose Radiators - is no longer an issue that should torment buyers.
