Centralized heating, which is carried out on the basis of water, can be of two types — open and closed. The open ventilation system has a two -pipe structure. Water in such an open system is heated using a boiler, and then using a pump, fed to convectors or radiators through pipes with small diameter. After that, the water goes back into the boiler so that it heats up through gas. Heating is carried out using solid fuel, which can be anthracite. Systems can be flexible because the operation of radiators or heaters can be adjusted automatically.
Also, if some rooms are not used, then heating in them can be disabled. Such heating can be used simultaneously with heating the house in hot water supply. If there is a desire to buy a hydromassage bath, it is better to choose a product with six nozzles, otherwise the water will simply begin to seethe with more. Modern nozzles can be adjusted, automatically closed so as not to waste water in vain, for example, when taking a shower or ordinary bathroom. The bathroom can also perform the function of aeromassage, which is carried out using microfoils. Closed heating is used as an alternative to an open system. On the gas line, water is supplied to the system, which is connected to the main water supply. So that the water in the water supply is not polluted, use the check valve. Water expansion during temperature rises into the pressure chamber.
