PURPOSE:To enable to control combustion of a bath boiler from a bathroom without providing a remote control means or the like in the bathroom, by providing a pressure-sensitive means at an intermediate portion of a circulation pipe, and controlling combustion of the bath boiler in response to the output signal of the pressure-sensitive means. CONSTITUTION:A bathtub 4 and a heat exchanger 2 in a bath boiler 1 are connected with each other via circulation pipes 5, 6, and a pressure-sensitive means 10 consisting of a diaphragm 12 having a pin 13 and a micro-switch 14 having a contact 15 is provided at an intermediate portion of the low-pressure circulation pipe 5, so that combustion of a burner 3 can be controlled through opening and closing of the micro-switch 14. With such an arrangement, combustion of the bath furnace 1 is controlled by operating the pressure-sensitive means 10 by developing a pressure P at the inlet of the circulation pipe 5 by forcing water into the pipe 5 manually or like, and thereby causing ON-OFF switching of the micro-switch 4. |
