PURPOSE:To pour hot-water by the simultaneous heating of a tap-controlled water heater and a bath boiler in combination and realize a large capacity by a method wherein a hot-water pouring pipe is communicated with the inlet water tube boiler section of a bath heater through an upper circulating pipe and a pump and is communicated with a lower circulating pipe under the sequence of the inlet water tube boiler section, a heat transfer tube and an outlet water tube boiler section. CONSTITUTION:Hot-water, delivered from a tap-controlled water heater 1, is poured into a hopper through a hot-water delivery pipe 2, a hot-water pouring valve 4 and another hot-water delivery pipe 5, thereafter, is guided between a pump 9 and an inlet water tube boiler section 8 by a hot-water pouring pipe 7. The circulating direction of the pump 9 is from an upper circulating pipe 11 side to the inlet water tube boiler section 8 side, therefore, hot-water in the hot-water pouring pipe 7 is heated by the heat transfer tube 12 of a bath boiler and is poured into a bathtub 10 through a lower circulating pipe 14. When water is remaining in the bathtub 10, the pump 9 is operated to send the hot-water from the hot-water pouring pipe 7 and the water in the bathtub 10 into the heat transfer tube 12 whereby they are heated and circulated. |
