For example, there are cases where the required amount of power consumption is small, but on the other hand, a large amount of hot water is required for operation. In such a case, the temperature of the exhaust gas from the prime mover 1 decreases, making it impossible to supply hot water at a predetermined temperature to the hot water accumulator 9. The hot water in C) is used as operating hot water. In addition, when restarting the prime mover 1 cannot be expected, the auxiliary heater 10 is activated to cool the hot water accumulator 9.
It is also possible to raise the temperature of the water and use it as hot water for operation.
