PURPOSE:To attempt to shorten the time spent for supplying hot water and save the fuel consumption by providing a bath boiler which heats the water entering a connecting pipe section from a water inlet provided in the side wall in a bath tub and supplies hot water from a water outlet by natural water convection with a water feeding means which forcibly circulates the water in the connecting pipe section from the water inlet to the water outlet. CONSTITUTION:A first water feeding section 27 is inserted into a water inlet 4 and a hook section 26 provided to a transmission section 11 is set on to the upper brim section 2a of a bath tub 2. And then, when the switch 18 of a power section 10 is turned ON, a motor 8 operates and its output rotates a propeller 7 through the transmission section 11. With this arrangement the water in the bath tub 2 is forcibly circulated in a connecting pipe section 5 from the water inlet 4 to the water outlet 3. At the same time the propeller 37 in a second water feeding device 33 is also rotated to stir the water in the bath tub 2. |
