PROBLEM TO BE SOLVED: To provide a water heater that can reduce the variation of the temperature of hot water in a bath terminal when hot water is supplied to the bath terminal.SOLUTION: A water heater includes: a hot water pipe 12 for supplying high-temperature hot water; a water supply pipe (13, 14) for supplying water from water source; a mixing means (15, 20) for mixing hot water from the hot water pipe 12 and the water supply pipe (13, 14); and a control device. A second predetermined opening degree is set between the first predetermined opening degree, the water flowing out from the outlets of the mixing means (15, 20) at activating the mixing means (15, 20) by the control device, and a setting temperature opening degree, the hot water at setting temperature flowing out from the outlets of the mixing means (15, 20). Meanwhile, an activation speed by the first predetermined opening degree is higher than that from the first predetermined opening degree to the second predetermined opening degree and that from the second predetermined opening degree to the setting temperature opening degree. |
