A system for heating and cooling room air and producing sanitary hot water, comprises a solar collector (1) provided with a tube bundle (5) of the high pipe type, and a main tank (2) for hot water connected to the water mains, a heat pump (4) interacting with the solar collector (1), additional heat sources in the form of electric water heaters, fan coil units for heating or cooling the room air, and control means responsive to sensors to actuate valves and circulation pumps. The heat pump (4) is connected to an isolated heat exchanger (27) for accumulation of hot water co-operating with the main tank (2) for producing hot water and adjusting the water temperature in the circuit of the fan coil units. |
