Cranes that control the drain of water from radiators should be located at the lowest point of the heating system, and the location of the expansion tank in the upper (under the surface of the ceiling or in the attic). The tank must be insulated, as well as install a drain tube in it through which excess water will be removed. The circular loop should be optimal length so as not to delay the movement of water. The boiler is usually installed in the basement at a height of 60 cm from the floor surface.
