<P>PROBLEM TO BE SOLVED: To provide a technique for miniaturizing a cogeneration system as a whole while the cogeneration system includes a hot water path and a heating path. <P>SOLUTION: When the operation of the cogeneration system for power generation is stopped and no usable heat is stored in a hot water tank 20, hot water in the heating path is heated by a burner 57 and low-temperature water in a second shared path 42 can be heated by the high-temperature water in the heating path. Thus even if the system has neither burner nor heat exchanger in the hot water path, the hot water in the hot water path can be heated by use of the burner 57 and a burner heat exchanger 60 which are disposed in the heating path. Because a heater consisting of a burner and a burner heat exchanger disposed in the system can be reduced to one while the system includes the hot water path and the heating path, the system can be miniaturized. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
