PROBLEM TO BE SOLVED: To provide a cogeneration system capable of preventing the decrease in the efficiency of a waste heat apparatus of a gas engine generator or the like when controlling the supply of hot water to a floor for heating based on a floor temperature. SOLUTION: The cogeneration system comprises a hot water storage system 1 for utilizing the waste heat of the waste heat apparatus of an engine generator 8 and the like for the heating of stored hot water using a heat exchanger 124 for stored hot water, and a floor-heating system 3 for utilizing the waste heat of the waste heat apparatus 8 for floor heating by a heat exchanger 204 for heating. The floor-heating system comprises a heating pump 301 for circulating hot water, a bypass path 304 for bypassing the discharged hot water in the heating pump, and a temperature detector 303 for an outward journey. Then, the temperature detector for a heating outward journey and the heat exchanger for heating are arranged at the side of a heating pipe to the bypass path. |
