摘要： PROBLEM TO BE SOLVED: To contrive that hot water in a heat transfer pipe is hardly overheated and hence scale is scarcely produced in the heat transfer pipe by providing a shielding mechanism for closing a return passage located upstream a bypass passage when supply hot water from a further building heat exchanger is supplied to the bypass passage. SOLUTION: A second bypass 24 is provided for connecting a position located between a circulation pump 70 of a return pipe 22 and a two-way valve 58 with a supply pipe 23 as a bypass passage for circulating and returning supply hot water from a heat exchanger 2 for bath additional heating to the return pipe without passage through a bathtub 100, and a three-way valve 59 is provided on a connection part between the second bypass pipe 24 and the supply pipe 23. Hereby, it is changed over to supply the supply hot water from the heat exchanger 2 for additional heating to the bathtub 100 or to supply the same to the second bypass pipe 24. Further, when the supply hot water from the heat exchanger 2 is supplied to the second bypass pipe 24, the two-way valve 58 serves as an interruption mechanism for closing the return passage 22 upstream of the second bypass pipe 24.
