Now consider the situation in which it is necessary to install heating, for example in the basement. In this case, it is not at all necessary to dig a pit to install the boiler, it will be enough to create a system of forced circulation of the coolant. To do this, an electric motor is installed in the heating system, the task of which is to pump the coolant through the pipes so that the coolant can overcome the intra -tube resistance. As a rule, the electric motor works on the principle of himself. That is, the engine repels heated coolant from itself and at the same time a new heated coolant constantly arrives to it. Thus, continuous circulation of the coolant in heating pipes is obtained.
