CONSTITUTION:At a remote controller 46 a hot water pouring switch 47 and an additional hot water supply switch 40 are installed. By the operation of the switch 47 or switch 48 the primary open and shut valve 30 and the secon dary open and shut valve 40 installed at a circuit 41 for pouring hot water to a bath are opened for a time previously set to supply hot water to a bathtub 23 and a timer controller 49 returning the valves to the shut state automatically is installed to supply hot water to the bathtub automatically. An open type tank 39 for isolation prevents the water in an inlet pipe 24 supplying the hot water to the bathtub 23 from back flow into a city water pipe.
