た。 Conventionally, hot water storage type water heaters have not been equipped with a device that detects the amount of heat of remaining hot water, and only some have been equipped with devices that detect the amount of remaining hot water. The amount of remaining hot water was also measured step by step by lining up multiple temperature sensors such as thermostats and thermistors on the outer wall of the hot water storage tank to detect temperature changes at those locations. For this reason, the remaining water heat value has not been utilized as data for the next boiling.

Provided in the middle of the communicating pipe 7 connected in the middle of the
Water is routed from the lower part of the hot water storage tank 1 to the connection part with the hot water supply pipe 4 via the communication pipe 7. In FIG. 2, reference numeral 10 denotes a residual water heat amount detection means to be described below, 11 a calculator A that calculates the amount of heat to be heated from the heat amount detected by the residual water heat amount detector 10, and 12 a calculator A that calculates the amount of heat to be heated from the heat amount detected by the residual water heat amount detector 10.

４図、T2（℃）の平均温度となつている。 Initially, the hot water tank 1 is filled with hot water at T 1 °C (Figure 1). FIG. 3 shows the temperature distribution inside the hot water storage tank 1 after using hot water of V 1 ( ) from the faucet 5 in this state. In other words, the lower part 1a of the hot water storage tank is filled with water from the water supply pipe 3 by the amount of hot water V 1 () used.
℃ water flows into the upper part 1b of the hot water storage tank at T 1 (℃).
V 2 () of hot water remains. In this state, if the circulation pump 6 is operated with the faucet 5 closed, the water in the lower part 1a of the hot water storage tank will flow through the communication pipe 7 from the upper part 1b of the hot water storage tank, disturbing the hot water layer in the upper part 1b of the hot water storage tank, so that the water level will gradually become average. The water gets warmer. FIG. 4 shows the temperature distribution of the hot water storage tank 1 where the hot water temperature has been averaged in this way, and the average temperature of T 2 (°C) is shown.
次に残湯熱量の求め方を説明する。貯湯槽１の
全容量をＶ（）（固有値Ｖ＝V1＋V2）とする

循環ポンプ６運転前の測定温度はｔ〔℃〕、循環
ポンプ６運転後の測定温度はT2（℃）なので、
残湯熱量Ｃ（KCal）は次の通り算出できる。 Next, we will explain how to calculate the residual heat amount. If the total capacity of the hot water storage tank 1 is V( ) (eigenvalue V = V 1 + V 2 ), then the temperature measured by the temperature detector 2 installed at the lower part 1b of the hot water storage tank before the operation of the circulation pump 6 is t [°C], and the temperature of the circulation pump is t [°C]. The measured temperature after 6 operations is T 2 (℃), so
The residual hot water heat value C (KCal) can be calculated as follows.
Ｃ＝Ｖ×（T2−ｔ）（Kcal）
次に演算器Ａ１１は加熱すべき熱量を算出する
もので、今、所要沸上り温度をＴ（℃）とする

よつて制御するものである。 C=V×(T 2 -t)(Kcal) Next, the calculator A11 calculates the amount of heat to be heated. Now, if the required boiling temperature is T (℃), the amount of heating heat Cin (Kcal) is It can be calculated as Cin=V(T-t)-C(Kcal). In addition, the calculator B12 calculates the required operating time.If the rated calorific value of the heat source is W (Kcal/Hr), the required operating time H is calculated as H=Cin/W(Hr), and the calculated operating time is is controlled by a timer device 13.

In addition, when this method is applied to electric water heaters that use late-night electricity, it can be expected to equalize the load by understanding the required operating time of each machine and allocating it appropriately, so it has great application effects.
