Battery heating: how to choose?
Often when repairing an apartment or a houseneed to buy heating batteries. Therefore, the question may arise which of them is better. Due to the huge variety of appearance, shapes and materials, it is difficult to make the right choice. A person who is not burdened with knowledge of what a heating battery is, there can be problems, so it is necessary to thoroughly deal with this issue.
There are a number of parameters characterizingoperating conditions of radiators. The main ones are the pressure in the system, the temperature of the coolant, and also the degree of its purity. The heating battery is available today in various variations, depending on this, there are very specific requirements for these parameters. If it is a private house, the coolant there is usually clean, of high quality, and the system is operated at a pressure of not more than three atmospheres. The temperature of the heat carrier usually does not exceed 95 degrees. If we talk about how to choose heating batteries for central heating systems, it should be noted that the coolant in this case is not too high quality, its temperature can be up to 120 degrees, and the working pressure is much higher than in private homes. It is these parameters that influence the choice of radiators.
Heating battery, cast-iron
Possess such batteries and certain disadvantages:
- afraid of hydraulic shocks;
- some models require preliminary drawing and painting.
If it is required to stabilize a given temperature regime in the room, then another drawback may be a large heat capacity.
Aluminum heating battery
Such radiators are characterized by excellentthermal conductivity and a low level of thermal inertia, and this allows them to actively use them to stabilize a certain temperature regime in the room. Such batteries look very attractive. They are produced in two types: conventional and reinforced. Conventional systems are used in systems where the working pressure is less than 6 atmospheres, that is, they can be installed in individual houses. The enhanced version assumes the possibility of operation at pressures up to 10 atmospheres. But they also have certain drawbacks:
- radiators are very susceptible to the purity of the coolant and its acidity level;
- at the junction with the steel pipe, the corrosion process may begin;
- due to the tendency to gas formation in the system, air congestion can accumulate.
Heating battery steel
- impossibility to add additional sections;
- they are afraid of excess oxygen in the heating system.
With this information, you can competently pick up suitable radiators for your home or apartment.
