PROBLEM TO BE SOLVED: To provide a hot water supply device that improves accuracy in a valve body position control in a mixing valve having both functions for mixing how water from as a hot water storage tank with water, and adjusting an ejection amount of the hot water.SOLUTION: A hot water supply device includes: a hot water storage tank 1 for storing high-temperature hot water; a mixing valve 5 for mixing water with hot water from the hot water storage tank; and a control device 16. The mixing valve 5 has a plurality of openings in a valve body. When the valve body is driven from the side of water, a flow rate variable region where a flow rate of only water varies exists for a specific section, and subsequently, a mixing region where hot water and water is mixed exists for a certain section. A start position of a position detection means of the valve body is defined as a position 38 where the flow rate from the side of the water in the valve body is almost minimum in the flow rate variable region. |
