<p><P>PROBLEM TO BE SOLVED: To provide a water heater enabling hot water temperature control suitable for each use state such as use for hot water supply in a kitchen or for a shower and use for filling hot water in a bathtub etc. even if a remote controller is broken. <P>SOLUTION: When determining, based on the communication with the remote controller 2 that the remote controller 2 is broken (S2), a hot water supply control part 7 provided in the water heater 1 sets a hot water supply temperature as a low-temperature set temperature (42°C etc.) preventing delivery of high-temperature hot water (S3). When hot water supply time is continued for a certain time (five minutes etc.) or longer, the hot water supply control part 7 changes the setting of the hot water supply temperature from the low-temperature set temperature to a high-temperature set temperature (48°C etc.) higher than the low-temperature set temperature (S7). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
