警報を発するようにしていた。2. Description of the Related Art When such a hot water supply apparatus is used, combustion products (CuCO 3 , CuSO 4, etc.) adhere to a heat exchanger, and the amount of the adhesion gradually increases. Since the combustion products adhere to the heat exchanger unevenly, the heat distribution of the heat exchanger becomes uneven, and the heat fatigue of the heat exchanger is promoted, which may damage the heat exchanger. It is necessary to remove combustion products adhering to the heat exchanger before it is damaged. Therefore, conventionally, a means for counting the use time or the number of times of use of the hot water supply device is provided, and when the use time or the number of uses reaches a preset value, the amount of combustion products attached must remove the combustion products. Judgment was made that the required amount of unnecessarily maintained maintenance was reached, and a maintenance alarm for removing combustion products was issued.

具合があった。However, the operating environment of the hot water supply device varies, and the difference in the operating environment causes a difference in the amount of combustion products deposited. Therefore, in order to avoid a situation in which the heat exchanger is damaged before issuing the maintenance alarm, the use time or the number of uses for issuing the maintenance alarm is set on the assumption that the use environment is relatively bad. Therefore, if the use environment in which the use time or the number of use times for issuing the maintenance alarm is set does not match the actual use environment, the actual amount of combustion products deposited may not be the amount required for maintenance. Regardless, since the maintenance alarm is issued, there is a problem that the maintenance alarm may be issued too early in some cases.
