The system has a hot water circuit (5) attached to a heat consumer by a heat exchanger (4), and a heating circuit attached to a burner unit (2). A four-way mixing valve (14) stands in connection with a forward-flow line (3) from a heater (1), with a forward-flow run line leading into the heating circuit, with a forward-flow line (7) from an additional heat source or from a buffer memory (9) and with a forward-flow line leading into the heat exchanger. A return pipe leading into the latter heat source or the buffer memory out-flows before the burner unit. The four-way mixing valve is a combination of a steering round and a throttle valve. |
