ルギー化を図ることができる。In the embodiment described above, after the power is turned on, the flow rate of the pump 15 is controlled so that the water temperature becomes 55°C by the temperature sensor Th5.
'. may be driven at a constant speed and operated such that the flow rate is kept constant.As described above, according to the present invention, the hot water temperature in the hot water storage tank is predetermined (if the water temperature is below the grade). When,
A heat pump and a combustion/combustion water heater are made at the same time as 81 years ago.
After the hot water reaches a predetermined temperature, it is heated and maintained by the combustion water heater, so the hot water storage temperature can be increased, and the capacity of the hot water storage tank can be increased unnecessarily. There is no need to do so, making it more compact, and furthermore, the fuel h1'' of the combustion water heater can be reduced, resulting in energy savings.
