When repairs are made to a dwellingit's up to the heating system, then often the owners are faced with the question: how to choose radiators for heating? And he asked for a reason, because the market is now represented by a huge variety of forms, materials of manufacture and appearance of devices, which can not help putting a simple philistine in a dead end.
How to choose radiators
If you do not have sufficient knowledgewith respect to heating systems, then for the right choice you need to pay attention to the operating conditions that you currently have, as well as the thermal capacity of the devices, design and maintenance requirements. Let's consider the requirements that are imposed on the operating conditions of radiators. The main parameters to be considered are the working pressure used in the heating system, the purity and temperature of the coolant. These parameters are very important in case of using different types of radiators. And then you have to consider the place where they will be used. For example, choosing radiators, heating for a private house - the main purpose of which, you can proceed from the fact that a quality heat carrier will be used, the pressure of which will be about 3 atmospheres, and the temperature - not more than 95 degrees. When used in a central heating system, the conditions are completely different, so it is worth considering this. To decide which heating radiator to choose, it is necessary to study the currently existing species.
Cast iron radiators
This type is used very widely.Cast iron radiators have a large heat capacity, even after lowering the temperature of the coolant they will remain hot for a long time. They are not afraid of the poor quality of the coolant, the temperature of which can be up to 130 degrees, the maximum working pressure is up to 15 atmospheres. There are also drawbacks. Such heat sinks do not benefit from hydraulic shocks, some models may require additional painting and preliminary pulling. Sometimes the large heat capacity becomes a big drawback. The most popular brands are such as GuRaTec, Viadrus.
Aluminum radiators
They have excellent thermal conductivity,inessential thermal inertia, due to what can be effectively used to stabilize the necessary thermal conditions in the room. The appearance of these radiators is very attractive. They are produced in the usual and reinforced versions. For central heating systems, the latter are preferable. When deciding how to choose radiators for heating, it is worth knowing about the disadvantages of aluminum: they are very sensitive to the purity of the coolant and its acidity level, electromechanical corrosion may occur at the junction with the steel pipe. Due to the propensity to gas formation in the heating system, air plugs may appear. The most popular brands are the following: Global, Rifar, Elegance.
Bimetal radiators
Such devices consist of a steel pipe andshell of aluminum. In appearance, they are comparable to those discussed above, and their design features eliminate them from such drawbacks as high requirements for heat carrier and hydraulic shocks. Such radiators are quite appropriate to use in high-rise buildings. But they also have certain drawbacks: a lower level of thermal power, which is due to the small internal section, the high cost due to the complex design. The most popular brands are Rifar and Sira.
Steel panel radiators
They can be installed in any systemheating. They are afraid of poor quality of the coolant, they have low thermal inertia, due to which it is possible to effectively regulate and maintain the temperature in the room. Disadvantages: in the heating system there should not be an overabundance of oxygen, radiators do not allow adding sections. The most popular brands are Purmo, Kermi.
Now you know how to choose radiators.
