Zusammenfassung:PROBLEM TO BE SOLVED: To provide a hot water supply device, reducing the power consumption of a water quantity sensor without lowering of sensitivity in a power-saving mode. SOLUTION: In this hot water supply device including the water quantity sensor 1 incorporating a Hall IC11 as a water quantity sensor, a switching element 22 is interposed on a power supply line to the water quantity sensor 1, and when the hot water supply device is in the power-saving mode, the switching element 22 is switched to apply pulse voltage as the driving voltage of the water quantity sensor 1. Thus, a heater 12 of the water quantity sensor 1 is operated intermittently to restrain power consumption of the heater 12. COPYRIGHT: (C)2005,JPO&NCIPI
