Abstract

A hot water storage-type hot water supply device is configured in such a manner that the amount of increase in the effective amount of heat within a hot water storage tank is increased to enable the device to operate efficiently. A hot water storage-type hot water supply device (1) for supplying heated hot water to a load circuit (300) which allows the user to utilize the hot water, wherein the hot water supply device (1) is provided with: a hot water storage tank (210) in which hot water is stored and which has outlets (231-233) for heating, said outlets allowing the hot water to be taken out to positions having different heights; an outlet selection section (430) for selecting an outlet for heating among the outlets (231-233) for heating, said outlet being that from which hot water is taken out, the selection being performed on the basis of the supply temperature which is the temperature of hot water supplied from the hot water storage tank (210) to the load circuit (300) and on the basis of the temperature of hot water taken out of the outlets for heating; and a heating section (100) for heating the hot water taken out of the selected outlet for heating and returned to the hot water storage tank (210).

Description

technical field [0001] The present invention relates to a heat storage type hot water supply device which heats water in a water storage tank and uses the water stored in the water storage tank to supply hot water. Background technique [0002] In the conventional heat storage hot water supply device, when the water in the storage tank is heated, the low-temperature water in the lower part of the storage tank is sent out from the outlet by the heat pump to a heating unit composed of a heat pump or the like, and is heated by the heating unit. High-temperature water is supplied to the upper part of the water storage tank later, and the whole water tank becomes high-temperature water gradually from the upper part of the water storage tank. [0003] And, the high-temperature water stored in the storage tank is used for hot water supply, heating, bathtub reheating, etc., especially in heating and bathtub reheating, etc., the heat of the high-temperature water stored in the storag...

AI Technical Summary

Problems solved by technology

Therefore, the above-mentioned conventional heat storage type hot water supply device has a problem that a large amount of water at a temperature that cannot be used as a load is stored in the water storage tank, so that effective heat decreases, and efficient operation may not be possible.
