<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply apparatus capable of ensuring high safety in supplying hot water in case of power failure. <P>SOLUTION: When a voltage detected by a voltage sensor 62 is a preset voltage V1 or less, a mixing valve 41 is operated so as to obtain a predetermined valve opening corresponding to a temperature T detected by a temperature sensor 63. This permits the mixing valve 41 to be driven by electric power when a voltage of a power supply 61 drops, and the mixing valve 41 to have such a valve opening that a temperature of hot water supplied to a user is a predetermined temperature or less, thus hot water at a predetermined temperature or less can be supplied to the user in case of power failure, and the safety in supplying hot water in case of power failure can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
