Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a cogeneration system capable of preventing heated water in piping from freezing without directly heating a heat medium circulation passage or a supply water passage in a power generator. SOLUTION: While a burner 32 of a reformer 30 is burning, combustion gas from it is emitted from a combustion gas blow port 33 into a power generation unit housing 21. While a burner 38 of a water boiling heater 50 is burning, combustion gas from it is emitted from a combustion gas blow port 47 into a heat accumulating unit housing 16. By emitting high temperature combustion gas, the inside of the housings 21 and 16 are heated. In a case where the burner 32 of the reformer 30 or the burner 38 of the water boiling heater 50 is stopped when temperature inside the housings 21 and 16 is lowered to require anti-freezing to the piping or the like, these are forcedly driven to emit the combustion gas. Atmospheric temperature is increased at a place where anti-freezing by combustion gas generated by combustion in an auxiliary heat source is necessary, thereby freezing in the piping such as the heat medium circulation passage 24 and supply water pipes 64 is prevented.
