The overall performance of the heating system installed in your house or the apartment, its profitability in many respects depends on what heating appliances are involved in it. Most often as heating appliances radiators and convectors are used, each of these types has the features, advantages and shortcomings.
Design features of radiator
Radiator – the hermetic device in which by means of the bringing and discharge pipe the continuous circulation of the heat carrier as which water or antifreeze is used is provided. Heating of the room is carried out in transfer of heat by means of infrared radiation from radiator surface. Than it is more and the heat carrier temperature is higher, the radiator will work more effectively, and the room will heat up quicker. Important role is played also by material of which the radiator is made it is good if it has the high thermal capacity and sufficient thickness.
Radiators are more economic, especially in houses with long-distance heating.
Design features of the convector
As follows from the name, this device by the principle of convection works. It is based on passing of air in the device, moving through heating coil, air mass extends and comes to the room, warming it while on vacant place the new portion of cold air comes to the body of the device. Air circulates in the convector body in the natural way, thanks to the created temperature drop. The overall performance of the convector depends on width of the channel on which air and arrangements of grids through which it arrives inside moves and comes to light.
What to choose – radiator or the convector
It is worth speaking about efficiency of radiator when it has rather big area, it is made of heatcapacious and heatinertial material, for example cast iron, and temperature of the heat carrier is about 90-95os. But, as a rule, these conditions are not always met – water temperature in heating systems seldom exceeds 80 wasps, the quantity of sections of household radiators is small and they are made aluminum or bimetallic, both those, and others with thin walls recently. Will turn out that even the best modern radiator, in fact, works as the water convector.
On sale there are convectors with the thick metal body made of alloy of steel and cast iron, they, in fact, work as traditional radiators, transferring heat at the expense of infrared radiation.
Radiators as water convectors, it is reasonable to establish in rooms with the increased area of glazing and high humidity, for example at offices, greenhouses, winter gardens, pools. For houses where there is long-distance heating, both bimetallic radiators, and air convectors will approach.
