As described above, while heating is being performed and when heating is stopped, hot water evaporates from the supply port (26) of the reserve tank (24), and the amount of hot water in the reserve tank (24) gradually decreases. For this reason, the reserve tank (24) is used throughout the year.
The amount of water that evaporates from the hot water circulation circuit (A) is, for example, 70 to 60 cc out of the amount of water (for example, 2000 cc) in the hot water circulation circuit (A), and if the air conditioner is used for several years, the water in the reserve tank (24) will run out. The water level in the hot water storage tank (9) gradually decreases. Even when water remains in the hot water storage tank (9), air is drawn from the hot water storage tank (9) to the hot water circulation circuit (A) by the operation of the circulation pump (10) and enters the hot water circulation circuit (A). Boiling occurs when the air passes through the hot water heat exchanger (8). Even when boiling occurs as described above, hot water remains at the bottom of the hot water storage tank (9), so the hot water temperature detector (17) can detect the water temperature, and the burner (7) ) is supplied based on the detected temperature, and the water temperature is adjusted to approximately 65% as described above.
The temperature can be controlled at an appropriate temperature from ℃ to 85℃, and the hot water circulation circuit (A
), it is possible to significantly extend the interval between water replenishment and simplify the maintenance work of air-conditioning equipment.

Since the temperature can be controlled to an appropriate level and there is no need to replenish water to the hot water circulation circuit for a long period of time, maintenance work for the hot water heating device can be simplified.
