PURPOSE:To fill a bathtub with hot-water to a predetermined water level promptly and correctly at all times. CONSTITUTION:In the control method of hot-water filling into an automatic bath boiler, which supplies hot-water and/or water into a bathtub based on a P-Q characteristics obtained by a pressure (P) corresponding to the water level of the bathtub 28 and the amount of water (Q) supplied into the bathtub 28, a specified flow rate of hot-water and/or water is conducted through a water conducting pipeline by a flow rate regulating means 47 provided in the water conducting pipeline and a flow rate as well as a pressure corresponding to the flow rate are detected by a pressure sensor 38. The detected value is stored in a memory unit and water of the same flow rate is conducted through the water conducting pipeline upon operation after next time while the pressure is detected and compared with the stored detecting value and the difference is utilized as the correcting value of the pressure sensor 38, then, the bathtub 28 is filled with hot-water while correcting the P-Q characteristic based on the correcting value of the pressure sensor, 38. |
