Storage type hot water supply system

摘要

In order to overcome a lack of high temperature water while intermediate temperature water generated in a hot water storage tank and to be used as water for hot water supply is taken out to an exterior without being stored in the hot water storage tank even when the intermediate temperature water is of a temperature lower than a required hot water supply temperature, a storage type hot water supply system includes: a hot water storage tank (2) for storing hot and cold water; a heat pump unit 3 for heating the hot and cold water fed from the hot water storage tank (2); a water intake tube body (38) provided in the hot water storage tank (2) while extended in an upper and lower direction, for guiding the hot and cold water to the exterior; and a hot water tap (4) to which the hot and cold water taken out to the exterior of the hot water storage tank (2) is guided, and is characterized in that the water intake tube body (38) is provided with at least an upper water-intake hole (40) formed near a top of the hot water storage tank (2) and an intermediate water-intake hole (43) formed lower than the upper water-intake hole (40).
