A storage water heater is provided that allows for improved maintenance of hygiene in a lower part of a hot-water storage tank and in a passage connected to the lower part of the hot-water storage tank. A storage water heater includes a heating device, a hot-water storage tank, a first passage, and a controller. The hot-water storage tank stores hot water. The first passage is connected to a lower part of the hot-water storage tank. The controller is configured to selectively switch between a heat-up operation and a recirculation operation. In the heat-up operation, hot water heated by the heating device is delivered to an upper part of the hot-water storage tank. In the recirculation operation, hot water flowing out from the upper part of the hot-water storage tank is delivered to the lower part of the hot-water storage tank via the first passage.
