You will not surprise anyone with an autonomous heating and hot water supply system in a private house. Whether it is a gas boiler or a boiler plant, domestic equipment solves the problem of heating water independently of a centralized system. This is followed by a responsible function of the distribution of the coolant at the points of consumption. In this infrastructure, a heating pump is used, which ensures the circulation of hot water
In almost every water heating system, sooner or later, the formation of gas accumulations in the pipes begins, which entails improper operation and circulation of the coolant. In such a system, increased noise and vibration occurs. Moreover, if a circulation pump is installed in the boiler, the ingress of gaseous substances into it can significantly reduce its service life
