Arrangement for heating the heat transfer medium of a heating circuit and for heating domestic water

摘要

In the case of an arrangement for heating the heat transfer medium of a heating circuit (1) and for heating domestic water, having a boiler (6) which is connected to the flow and return pipe (3, 5) of the heating circuit (1), there is provided a water storage tank (17) which has a lower heat storage zone (18) and an upper domestic water zone (19). Provided in the transition region between these zones (18, 19) is a heat exchanger (15) which is connected to a secondary circuit (14) for the heat transfer medium of the heating circuit (1) and is in series connection with a heat exchanger (16) in the bottom region of the water storage tank (17), it being possible for this heat exchanger (16) in the bottom of the water storage tank (17) to be short-circuited as a function of the return temperature of the heating circuit (1). <IMAGE>
