A cogeneration system that allows an engine to be continuously operated even when there is no demand for hot feedwater. The system comprises a hot water tank for storing hot water heated from cold water by heat released by an engine that drives a generator. When the heat of the water in the hot water tank exceeds a predetermined temperature, a control is performed so that a drain valve is opened and the hot water in the tank is released.
