Abstract

Provided is a storage type hot water supply device, which can suppress the drop in an energy efficiency while activating a release valve as in the prior art. A bypass passage (41) is equipped with a heat exchanging unit (3) and a pump (12) for a bath. A release valve (43) is connected to the bypass passage (41) so that the energy loss is suppressed by releasing not hot water but cold water. A communication passage (46) provides the communication between the upper portion of a hot water reserving tank (2) and the bypass passage (41) while bypassing a constricted portion (44) and an air-reserving portion (45), and a check valve (47) is mounted in the communication passage (46). The check valve (47) is so constituted as is opened not by the differential pressure, which is established by the convection from the upper portion of the hot water reserving tank (2) via the bypass passage (41) to the hot water reserving tank (2), but by the differential pressure which is established by the drive of the pump (12), thereby to prevent the convection loss.
