<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply device capable of avoiding wasteful consumption of hot water by fully opening a mixing valve to a tap water side and preventing output of stored hot water when a freezing prevention setting means is activated, a hot water supply opening is slightly opened, and supply hot water in the piping is passed through for preventing freezing of the hot water supply piping during nonuse at a winter night or the like. <P>SOLUTION: The hot water supply device has the mixing valve 4 mixing tap water branched from water supply piping 2 with hot water of hot water supply piping 3, and the freezing prevention setting means for preventing freezing. When the freezing prevention setting means of a controller 8 is set by a remote control 9, the controller 8 fully opens the mixing valve 8 to the tap water side to prevent output of the hot water into a hot water storage tank 1. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
