Abstract
A hot water supply apparatus includes a heat pump device in which a compressor and a heat exchanger are connected, a heat medium circuit connected to the heat pump device via the heat exchanger, a tank that stores water after the water exchanges heat with a heat medium of the heat medium circuit, two tank-temperature detection units attached at different heights to the tank and each detects a temperature of water in the tank, and a controller that controls, by using a value detected by each of the two tank-temperature detection units, a temperature of water in the tank. The controller sets a target hot water supply temperature based on a stored-hot-water temperature detected by one of the two tank temperature detection units and a within-tank temperature difference that is a difference between temperatures within the tank detected by the two tank-temperature detection units.
