In a cogeneration apparatus (10), a heat exchanger (14) includes an exhaust gas passageway (82) for passage therethrough of exhaust gas, a heat medium passageway (83) for passage therethrough of a heat medium that gives heat energy to a water heater etc., and a water passageway (84) for taking heat from the exhaust gas and giving the heat to the heat medium. Cooling water for a water-cooled engine (12) is given to the water passageway (84). The cogeneration apparatus requires reduced numbers of the heat exchanger and pipes, and hence a reduced number of necessary component parts, so that the cogeneration apparatus can be reduced in cost. |
