Valves (4) are installed to cut off the circulation in the cooling or heating conduit, whichever is not in use. At the lower exit pipe of the radiators (7) is an installed air-recycling device (6,10), which operates under the pressure generated by the liquid cooling-agent circulating in the conduit, or alternatively by means of an electric fan.
