PURPOSE:To permit to discharge a large amount of high-temperature hot-water through a compact device and shorten a time until bathing by a method wherein water of given temperature, obtaind 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 transfer 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 is connected to the hopper 27 of the bathtub 11 through a solenoid valve 25. A single tube type heat transfer tube 12 is penetrated through the heat absorbing fins 13 of the bathtub 11 and a hollow jacket 16, provided with circulating inlet and outlet pipes 14, 15 at one side wall and with an outlet section 12b opposing to the inlet part 12a and circulation outlet pipe 14, is provided while the heat transfer tube 12 is connected to the inlet part 12a and the outlet part 12b. As a result, the capacity of hot-water supplying and bathwater supplyng may be developed at the rated capacities thereof in case of the independent using and simultaneous using of the hot-water supplying and the bathwater supplying. |
