Abstract (en)

[origin: EP1447626A1] The hot water storage tank (6) has a cold water inlet (12), a hot water outlet (13) and a lower cold water outlet (4) with a circulating pump (7). The circuit also has a heat exchanger (9) to which a hot water pipe (5) in the upper area of the tank opens. The heat exchanger has a heating circuit (H) with a heater (10), pump (8) and in and return pipes (11,14). The return connection is controlled dependent on the storage tank temperature.
