In a hot water storage water heater having a hot water storage tank, a water supply pipe for supplying water to the tank, a hot water discharge pipe for discharging hot water from the tank, and a mixing valve for mixing water branched from the hot water supply pipe and the water supply pipe, A valve body for adjusting the amount of water flowing into the vessel, and the mixing valve operates the hot water amount adjusting valve by a balance of the spring load of the shape memory alloy spring and the bias spring, and the bias spring is attached to the mixing valve body. It is fixed by screwing, the temperature can be adjusted by varying the deflection load of the bias spring, and the water flow rate on the water side is constant, and only the water flow rate on the hot water side is controlled. Hot water storage type water heater featuring The hot water storage type hot water heater according to claim 1, wherein a water supply amount is controlled by making a hole on the water supply side of the mixing valve into an elliptical shape. The hot water storage water heater according to claim 1, wherein the water supply amount is controlled by positioning the water supply side hole of the mixing valve above or below the center of the cylindrical connection port. The hot water storage type water heater according to claim 1, wherein a valve having a check mechanism is mounted in front of the hot water supply side of the mixing valve. The hot water storage type water heater according to claim 1, wherein an orifice-shaped pressure loss plate for limiting the amount of water supply is mounted on the water supply side of the mixing valve. Based on the use detection means for detecting the use of hot water in the hot water storage tank, the use detection time information storage means for recording use detection time information related to the time detected by the use detection means, and the stored use detection time information The control content determining means for determining the control content of the heater energization time, and a temperature control unit for controlling the temperature in the hot water storage tank based on the determined control content of the heater energization time. No hot water heater.
