摘要： PROBLEM TO BE SOLVED: To provide proper heat efficiency insofar as possible in each operational state, by minimizing the difference between the heat efficiency in a single operational state and that in a simultaneous operational state. SOLUTION: A combustion type of heating apparatus is constructed so that a plurality of heat exchanging parts N1 and N2, which heat the liquid to be heated and supplied from an inlet line Li during passing through it and discharge the liquid into an outlet line Lo, are arranged lengthwise of a combustion gas passage of a combustion burner 2, and that supplying of the liquid to be heated for each of the heat exchanging parts N1 and N2 is intermittent by each part. In this case, a control means RT is provided to automatically regulate the flow rate of the liquid to be heated in said heat exchanging part N1 (N2) in the state wherein the liquid to be heated is supplied, so that the flow rate in the simultaneous operational state wherein the liquid to be heated flows in the other heat exchanging part N2 (N1), is smaller than that in the single operational state wherein the liquid to be heated in the other heat exchanging part stops to flow.

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.
