夜の２３時から翌朝の）７時までの８時間でめる。Figure 1 is a cross-sectional view of a general hot water storage type water heater that uses electricity as a heat source, and Figure 1 shows the main power supply circuit of a conventional hot water storage type water heater that uses electricity late at night. In the figure, 1 is a hot water storage tank, 2 is a heating element, 3 is an automatic temperature controller, 4 is a power supply, and 5 is a time switch for late-night electricity.9 The power-on period is generally from 11:00 p.m. to 7:00 a.m. the next morning. Finished in 8 hours.
発熱体２は深夜電力の通電時間内に冬期の水温に相当す
る８°Ｃ前後の水を８５°Ｃに沸上げるようにその容量
が予め設定されている。The capacity of the heating element 2 is preset so as to boil water at around 8°C, which corresponds to the winter water temperature, to 85°C during the late-night power supply time.

７時には貯湯量全部が８５°Ｃに線上がっている。Next, the function and operation will be explained. At the time when the late-night power coupling starts, the contact of the time switch 5 closes and the heating element 2
energization starts. The water temperature in hot water storage tank 1 is 85°
When CK is reached, the contacts of the automatic temperature controller 3 open and the heating element 2
The power supply to is stopped. After that, when the water temperature drops due to natural heat radiation, the automatic temperature regulator 3 closes and the heating element is energized again, and by repeating this opening and closing operation, the entire stored hot water reaches 85°C by 7am every morning. The line is rising.

期に比し適温湯が多量に採湯できる。However, the amount of hot water used and the water supply temperature are not always the same.9
The days vary greatly depending on the season. In particular, whether you take a bath or not is a factor that greatly affects the amount of hot water used, and on days when you do not take a bath, more than half of the stored hot water may remain. Also, depending on the season, the temperature of the water supply has a big impact on the amount of hot water that can be extracted, and in the summer when the water supply temperature is high, a larger amount of hot water can be extracted than in the winter.
しかし湯の使用量は年間はぼ一定か、むしろ夏期の方が
低温湯で団用するため、実質的な使用量が低下するのが
一般的でｂす、夏期の残湯量が多くなる。However, the amount of hot water used is generally constant throughout the year; in fact, the actual amount used generally decreases in the summer because people use low-temperature hot water, and the amount of hot water remaining in the summer increases.
このように不必要に高い温度の湯を長時間使用に供さな
