摘要:
A single can-type composite heat source machine including a single can body including a first combustion section having a first burner and a hot water supplying first main heat exchanger located above the first burner, and a second combustion section having a second burner and a second main heat exchanger located above the second burner and used for a purpose other than hot water supply. The first combustion section and the second combustion section are partitioned from each other by a partition wall and juxtaposed in a lateral direction. The machine includes a first auxiliary heat exchanger and a second auxiliary heat exchanger both of a latent heat recovery type connected to upstream sides of the first main heat exchanger and the second main heat exchanger, respectively. An exhaust system can be miniaturized and simplified in spite of provision of the auxiliary heat exchangers.
