Abstract
A hot-water storage type hot-water supply apparatus operates under a natural circulation principle wherein hot-water is accumulated within a hot-water tank by circulating cold water or hot-water contained therein through a first circulation pipe connected to the bottom thereof, a heat exchanger, and a second circulation pipe. A thermal valve is mounted in the second circulation pipe downstream of the heat exchanger such that its opening area is varied depending upon the hot-water temperature in the second circulation pipe so as to maintain the temperature of the hot-water flowing out of the heat exchanger at a substantially constant temperature, resulting in the temperature distribution of the hot-water within the tank at the time of its boiling being kept substantially constant throughout the storage tank instantaneously at the start of the boiling of the hot-water.
