た時は補助ヒータ５をＯＦＦする（Ｓ１０）。If the result is determined to be normal, the heater control unit 9 determines whether the hot water temperature data detected by the auxiliary hot water temperature detection means 7 is 120 or more (S6). At this time, if it is less than 42°C, the heater control unit 9 turns the auxiliary heater 5 ○NL (S7), and conversely, if it is t7°C or more, turns off the auxiliary heater 5 (S8).
. When the abnormality detection means 8 determines whether or not the hot water temperature data detected by the auxiliary hot water temperature detection means 7 is normal (S5), if it is determined to be abnormal, the heater control section 9 changes the hot water temperature data detected by the main hot water temperature detection means 6. Determine whether the temperature data is below 13℃ (S
9). As a result, when it is determined that the temperature is less than t1°C, the heater control unit 9 turns on the auxiliary heater 5, and conversely, when it is determined that the temperature is higher than t1°C, it turns off the auxiliary heater 5 (S10).

As a result, if it is determined that there is an abnormality, the main water temperature detection means 6. Since both the auxiliary hot water temperature detection means 7 are abnormal, the heater control unit 9 turns off the main heater 4 and the auxiliary heater 5 (512). If it is determined to be normal, the heater control unit 9 determines whether the hot water temperature data detected by the auxiliary hot water temperature detection means 7 is equal to or higher than t4°C (Sl3). At this time, when it is determined that the temperature is lower than 14°C, the heater control unit 9 sets the main heater 4 to 0NL (514).

Further, when it is determined that the temperature is t4° C. or higher, the main heater 4 is set to ○FFL (S15), and the process proceeds to the route of determining whether the hot water temperature data detected by the auxiliary hot water temperature detection means 7 is 420 or higher (S6). The following operations are as described above.
