Summary:In a cogeneration system having a generation unit equipped with a generator and an internal combustion engine, there is installed with a hot water unit including a first flow channel connecting a water supply source with a thermal load, a heat exchanger exchanging heat between water flowing the first flow channel and engine coolant, a first electromagnetic solenoid regulating flow rate of the water heated by the heat exchanger, a second flow channel connected to the first flow channel, a boiler heating water flowing through the second flow channel, and a second electromagnetic solenoid regulating flow rate of the water to be heated by the boiler. The temperatures of the engine coolant and water at the first and second flow channel joint are detected and operation of the first and second valves is controlled based on the detected temperatures, rendering hot water tank unnecessary, thereby achieving the compact structure.
