。[I] Heating operation First, during heating, in the cooling water circulation system A, the high temperature cooling water from the engine 1 reaches the heating heat source water heat exchanger 3, where it exchanges heat with the water in the heat source water circulation system B. At the same time, the temperature of the heat source itself decreases and reaches the heat recovery heat exchanger 7. Then, in the heat exchanger 7, the water in the water supply system C undergoes heat exchange 1 to raise its temperature, and the temperature of the water itself further decreases to reach the cooling system A. At this time, if the temperature of the cooling water is below a predetermined temperature (for example, 75°C), the three-way valve V3 connects the ports shown by hatching in FIG. is bypassed and recirculated to the engine 1 via the bypass route A1. If the temperature of the cooling water remains above the predetermined temperature even after passing through the heat exchangers 3 and 7, the three-way valve V3 connects the ports indicated by hatching in FIG. 2(b), thereby cooling the water. The water passes through the cooling device 4 and returns to the engine 1 at a temperature below a predetermined temperature.

The heat source water is circulated through the heat exchanger 3 with the ports indicated by hatching in FIG. Warmth is done. By operating the heat pump unit U with the electric power generated in the power generation device 2, the heat pump unit U is able to remove heat from the heat source water that circulates as a heat source and perform the specified heating. In this case, the heat pump unit U can be operated efficiently by operating when the heat source water reaches a predetermined temperature (for example, 40 degrees Celsius) or higher. If the temperature of the heat source water gradually rises due to low heat consumption,
When the temperature reaches a predetermined temperature (for example, 45°C) or higher, the three-way valve V2 is placed in communication between the boats shown by hatching in FIG. 2(d), and the heat source water bypasses the heat exchanger 3. , heating bypass path f!
