PROBLEM TO BE SOLVED: To provide a hot water supply device capable of achieving a warm/cold shower of stable temperature fluctuation even when a combination faucet is used, and having excellent usability.SOLUTION: A hot water supply device comprises: a mixing valve 4 for mixing hot water heated by heating means 1 with water whose temperature is lower than that; hot water supply temperature setting means for setting temperature of hot water/water mixed by the mixing valve and supplied to a hot water supply terminal 7; and a control device 9. The control device has an operation mode in which a mixture ratio of the mixing valve is changed and the temperature of the hot water/water flowing from the mixing valve to the hot water supply terminal is made to fluctuate high and low repeatedly. The control device sets the mixture ratio of hot water/water in the mixing valve in such a manner that temperature difference of the hot water/water generated by the mixing valve in the operation mode becomes larger in the case where the setting temperature at the hot water supply temperature setting means is a predetermined temperature or higher than the case where the setting temperature is lower than the predetermined temperature. |
