Abstract: PURPOSE:To remove the positional restriction of hot-water feed taps and to enable to  install the hot-water feed taps even on the second floor, by providing a pressure detecting means in a hot-water feed pipe branched from a heat collecting pipe, and obtaining  a pump starting signal from the output of said pressure detecting means. CONSTITUTION:When a heat collector 1 is heated by the solar rays and the temperature difference of the heat collector 1 and a heat accumulating tank 2 is increased, it  is detected by a high-temperature sensor 17 and a low-temperature sensor 18, and a pump 5 is set into operation by the aid of a control means 19. Here, since a two-way  valve 8 is opened and a three-way valve 6 is communicated with a lower portion of  the heat accumulating tank 2, water in the tank 2 is supplied to the heat collector 1,  where heat is collected. On the other hand, when hot-water feed taps 13 is opened for  feeding hot water, pressure in a pipe 4 is lowered and the two-way valve 8 is closed  through operation of a pressure switch 10. At the same time, the three-way valve 6 is  shifted to communicate with a by-pass pipe 7, so that hot water at the upper portion  of the tank 2 is supplied to the taps 13 by the pump 5. Here, fluctuation of pressure  caused, for instance, at the time of starting the pump 5 is absorbed by a tank 12.
