れる。In step S1, when the resident informs the manager of the expected date of occupancy, the manager checks the unit number of the contacted resident and sets the unit number in the unit number setting unit (14) ( Step S2), the control line (3) between the centralized control device (1a) and the water heater (4) of the dwelling unit is connected. Then, the power supply instruction input unit (19) is operated to send a power supply start instruction to the control line (3) (step S3). In response to the instruction to start energization, the power switch (12) of the water heater (4) of the dwelling unit is turned on (step S4), and the heating element (9) is energized.
Boiling of water supplied to the hot water storage tank (5) is started.
なお一般的な貯湯式温水器では、貯湯タンク（５）に
給水されている約10℃の水を８時間の通電で約85℃に沸
上げるように、発熱体（９）の定格が設定されており

ンク（５）内の湯温を維持するようになっている。In a general hot water storage type water heater, the rating of the heating element (9) is set so that water of about 10 ° C. supplied to the hot water storage tank (5) is heated to about 85 ° C. by energizing for 8 hours. (For example, if the capacity of the hot water storage tank (5) is 370, 4.4 kW), it consumes a considerable amount of power. In order to be able to boil at any time at the time of occupancy, we do not use electricity at midnight in particular. Therefore, as soon as the heating element (9) is energized, boiling starts and the automatic water temperature controller (10) turns on the hot water storage tank. When the water temperature in (5) reaches 85 ° C., the energization is stopped, and thereafter, each time the water temperature falls below a certain temperature, the energization to the heating element (9) is repeated, and the hot water temperature in the hot water storage tank (5) is reduced. It is supposed to be maintained.
なお最初の沸上げ時間は水温によっても異なるが、貯
湯タンク（５）内に残湯がない状態で６時間から９時間
が必要となる。Although the initial boiling time varies depending on the water temperature, 6 to 9 hours are required in a state where there is no remaining hot water in the hot water storage tank (5).

い場合が生じる。[Problems to be Solved by the Invention] The conventional centralized control device for an electric water heater as described above is configured as described above.
It is necessary to start energization of each water heater at the optimum time considering the boiling time of about 8 hours for each occupancy time specified by each resident at different dates and times. It is impossible to force the caretaker, and after all, the power supply starts earlier than the optimal time, causing energy loss due to heat release after boiling, or even if the power supply is too slow and the resident arrives, it is still not enough In some cases, boiling is not completed.
また制約を設けずに各戸の温水器に通電が開始される
ため通電時間が重複し、大容量の電源設備を備えておか
ねばならない等の問題点があった。In addition, since power is supplied to the water heater of each house without any restrictions, the power supply time is duplicated, and there is a problem that a large-capacity power supply must be provided.
