Zusammenfassung:	PROBLEM TO BE SOLVED: To improve safety and COP by utilizing water of intermediate temperature with priority and preventing outflow of contamination in an intermediate-temperature water use inhibition mode. SOLUTION: When the intermediate-temperature water use inhibition mode is judged by an intermediate part temperature detecting means 136 and an upper part temperature detecting means 137, a first mixing valve 120 is kept in a water-side full open state, mixing control thereafter is inhibited, and the control inhibition state of the first mixing valve 120 is released to recover normal operation when the completion of total volume boiling-up operation is confirmed.
