Abstract: PURPOSE:To enable to produce hot water effectively, by changing the substantial capacity of a hot-water storing tank by moving a suction port and a return port vertically in the tank in response to the output signals of water temperature sensors disposed in the vicinity of the suction port and the return port. CONSTITUTION:Water in a hot-water storing tank 6 is supplied to a heat collector 2 by a circulating pump 10, and the temperature T0 of heated water is detected by a high- temperature sensor 4. A holder 48 disposed in the tank 6 in a vertically movable manner has a suction port 16, a return pipe 18, a low-temperature sensor 8 and a hot-water temperature sensor 60 attached to its upper plate. When the temperature difference of T0 and the temperature T2 of hot water in the tank detected by the sensor 8 becomes larger than a prescribed value, a first control unit 20 drives a pump 10 to feed water from the suction port 16 to the heat collector 2. Further, when the temperature (t) of hot water detected by the sensor 60 is lower than a prescribed value T3, a third control unit 64 moves the holder 48 upward by means of a hoisting drum 42 and stops it when the temperature (t) becomes equal to T3, thus further producing high-temperature water. In summer, the substantial capacity of the tank is increased by moving the holder 48 downward. Thus, it is enabled to produce high-temperature water effectively.

Moreover, in the connection between the master set 1 and the 1st slave set 3, since the power supply isolation circuit 61 and the dummy resistor 62 are not acted, the slave set power is normally supplied from the master set 1 to the 1st slave set 3. Thus, the slave sets 3, 5 do not exist in mixture in one and same video interphone system.
