Summary:PROBLEM TO BE SOLVED: To provide a hot water supply system capable of performing heat storage efficiently by using surplus power.SOLUTION: When surplus power exists in which used power is subtracted from generated power generated by a photovoltaic power generator 70, by using the surplus power, a control device 90 executes a low temperature hot water storage operation for operating a heat pump 10 so that the temperature of hot water passing on an outlet side of the heat pump 10 out of a tank circulation path 30 becomes a hot water supply setting temperature Ts+5°C. After a tank 20 is filled with hot water of the hot water supply setting temperature Ts+5°C by the low temperature hot water storage operation, in the case where the surplus power exists, by using the surplus power, the control device executes a high temperature hot water storage operation for operating the heat pump 10 so that the temperature of the hot water passing on the outlet side of the heat pump 10 out of the tank circulation path 30 becomes 90°C or higher.SELECTED DRAWING: Figure 1 【課題】余剰電力を用いて効率よく蓄熱を行うことができる給湯システムを提供する。【解決手段】制御装置90は、太陽光発電器70によって発電される発電電力から使用電力を除いた余剰電力が存在する場合に、その余剰電力を用いて、タンク循環路30のうちのヒートポンプ10の出口側を通過する温水の温度が給湯設定温度Ts+5℃になるようにヒートポンプ10を運転させる低温貯湯運転を実行し、低温貯湯運転によって給湯設定温度Ts+5℃の温水がタンク20に満たされた後に、余剰電力が存在する場合に、その余剰電力を用いて、タンク循環路30のうちのヒートポンプ10の出口側を通過する温水の温度が90℃以上になるようにヒートポンプ10を運転させる高温貯湯運転を実行する。【選択図】 図1
