The system has a primary heat exchanger (3) connected to tank (33) and radiators (10). A solar heater (19) is connected to the system via a heat exchanger (18) in the tank, which has a cold water outlet (32) at the bottom. A cold water feed (50) is connected via a three-way path valve (52) to the cold water outlet and the return pipe (51) of a heat exchanger (13), resp. its secondary circuit (31). Its primary circuit (12) is connected to the primary heat exchanger (3) via heat exchanger feed and return pipes (11,30), and the radiator system is also connected to these pipes. |
