<p>PROBLEM TO BE SOLVED: To ensure smooth heating even when air is accumulated in a heat storage tank by providing a mixing valve at a higher position than an outtlet hole of a high temperature water pipe line from the heat storage tank, and providing an inlet part of a bath water pipe line to the mixing valve at a higher position than the high temperature watier pipe line. SOLUTION: A mixing valve 3 is mounted at a higher position than a high temperature water outlet the 40 of a high temperature water pipe line 2, and a bath water inflow part 30 is disposed at a higher position than the high temperature water pipe line 2. Accordingly, bath water is introduced into a heat storage tank introduction pipe line 6 and a bath water in the heat storage tank 5 and bath water the high temperature water in the heat storage tank 5 and bath water in the bath water pipe line 1 are simultaneosuly raised, the high temperature water first fills the high temperature water pipe line 2 and is supplied to the mixing valve 3. Hereby, even when air is accumulated in the heat storage tank 5, the high temperature water and the bath water are mixed in the miximg valve 3 for smooth heating.</p> |
