Even if 40 does not fall below the reference temperature T 1 , hot water heating equipment
When the hot water heating operation by 10 is performed, the antifreezing means of the general hot water supply equipment 20 and the antifreezing means of the bath reheating equipment 30 are turned on for a certain time H every time a certain time H 1 elapses.
Turns on 2 to prevent freezing. That is, with reference to FIG. 3, a control example of the antifreezing operation by the control unit 50 will be generally described. Now, with the power supply of the water heater turned on, the control unit 50 monitors the ambient temperature detected by the ambient temperature sensor 40, and the ambient temperature is the reference temperature T 1.
If it is below the reference temperature T 1 (YES in step S1), the general hot water supply facility 20, the bath reheating facility 30, the hot water heating facility 10 are determined.
The antifreeze operation is performed (step S2). However, general hot water supply equipment 20, bath reheating equipment 30, hot water heating equipment 10
In each of the above, when the hot water supply operation, the reheating operation, or the hot water heating operation is performed, the antifreezing operation is not performed for the equipment performing the operation. In the above, the anti-freezing operation of the general hot water supply facility 20 is performed by turning on the anti-freezing means, that is, the can body heat retaining heaters 71 and 72, the water filter device heat retaining heater 73, the water amount sensor heat retaining heater 74, and the water amount controller heat retaining heater 75. To do. In addition, the antifreezing operation of the bath reheating facility 30 is performed by antifreezing means, that is, a reheating circulation pump warming heater.
This is performed by turning on the antifreezing circulation of 81 and the reheating circulation pump 32. In addition, the antifreezing operation of the hot water heating facility 10
Heating hot water circulation pump Insulation heater 61 and heating hot water circulation pump
This is done by turning on the 12 antifreeze circulation. When the antifreezing operation has passed a predetermined time H 2 (Yes in step S3), the antifreezing operation is turned off by temporarily turning off each antifreezing means (step S4), and the process returns to step S1.

It is determined whether or not the operation is turned on (step S5), and if the hot water heating operation is on (YES in step S5), it is further determined whether or not a certain time H 1 has elapsed in the hot water heating operation state. (step S6), a predetermined time H 1 when elapsed (yES in step S6), the start freezing prevention operation of the general hot water supply facilities 20 and the bath reheating equipment 30 is equipment other than hot water heating plant 10 (Step S7). The antifreezing operation of the general hot water supply equipment 20 is performed by turning on the antifreezing means of the general hot water supply equipment 20. The antifreezing operation of the bath reheating facility 30 is performed by turning on the antifreezing means of the bath reheating facility 30. When the antifreezing operation has passed H 2 for a certain period of time (Yes in step S8), the control unit 50 turns off each antifreezing operation to temporarily end the antifreezing operation (step S9), and returns to step S1.

According to the hot water supply device described in (1), while the hot water heating operation is continued, even if the temperature detected by the ambient temperature sensor arranged in the device case is not lower than the reference temperature for performing the antifreezing operation, It has a control unit that forcibly performs the antifreezing operation of the above-mentioned other equipment for a certain time every time the operation has passed a certain time, so when the hot water heating operation of the water heater is continuously performed for a long time. , Due to the influence of the hot water heating operation on the ambient temperature, there will be a gap between the temperature detected by the ambient temperature sensor and the temperature condition of other general hot water supply equipment such as the hot water supply equipment or bath reheating equipment It is possible to prevent the facility and bath reheating facility from freezing. That is, the adverse effect of the hot water heating operation in the hot water heating equipment of the hot water supply device is reliably eliminated, the antifreezing operation in the other equipment of the hot water supply device is reliably performed, and the freezing situation can be reliably prevented.
