<p>PURPOSE: To take out hot water at any time in a short time even after the hot water is run out by providing a hot water supply connecting pipe through which the upper parts of hot water storing tanks and a heating tank communicate together and providing a water supply connecting pipe through which the lower parts communicate with each other. CONSTITUTION: Respective hot water storing tanks 81 and 82 are completely filled with water through a water supply connecting pipe 24 for supplying water to a heating tank 1. Under this state, when the heater 5 of the heating tank 1 is turned on, the part in the heating part 1B of the heating tank 1 is heated with the heat of the heater 5, a temperature sensing shut-off valve 11 is opened, so that hot water HW is raised in a hot water guide pipe 10, fed and stored into the upper part of a hot water storing part 1A. Since the specific weight of the hot water HW is smaller than that of water, the hot water HW tends to rise, so that the hot water is distributed and stored in the respective upper parts of the storing tanks 81 and 82 through a hot water supply connecting pipe 25. Thus, the hot water HW can be taken out at any time and the hot water HW can be taken out in a short time even after the hot water is run out.</p> |
