PURPOSE:To permit to discharge a large amount of high-temperature hot-water through a compact device by a method wherein water of given temperature, obtained by a tap- controlled water heater, is sent into a heat transfer tube for bath to reheat and send it into a bathtub. CONSTITUTION:A bath heater, equipped with a vertical rise-up tube 26 at a part of a heat ransfer tube 12 having heat absorbing fins 13 and with a hopper 27 at the tip end thereof, is composed with the tap-controlled water heater 17. The hot-water supplying pipe 22 of the tap-controlled water heater 17 is branched and one side thereof is connected to a hot-water discharging pipe 24 having a hot-water supplying cock 23 while the other side thereof is connected to the hopper 27 of the bathtub 11 through an opening and closing valve 25. According to this constitution, a function as two heaters two water ways system can be achieved, therefore, the rated capacity maybe developed either in case of simultaneous using or independent using for hot-water supplying. Further, in case large amount of high-temperature hot-water is to be discharged into a bathtub, the hot-water, obtained by the tap-controlled water heater, is sent into the heat transfer tube for bath and is poured into the bathtub under reheating it, therefor, the capacity may be enlarged. According to this method, the capacity of the device may be enlarged and the size of the device may be made compact. |
