PURPOSE:To make it possible to use with a maintenance requirement equivalent to a convection-type one by a simple structure in the tille boiler for bathtub etc. by disposing a pump driven by the steam pressure generated by a burner etc. in a heat exchanger. CONSTITUTION:A forced circulating device 5 containing water is heated by a burner 6. Because of this, the water in the device 5 is boiled and forced into a heat exchanger 4. Due to this, a vacuum is generated in the device 5 which causes the water to be taken in, and such water is heated and is again forced out. By the repetition of such, the water in the heat exchanger 4 is forcibly circulated. By this constitution, the structure is simplified, and can be handled with a maintenance requirement equal to a convection-type. |
