<p>PURPOSE: To permit supply of hot-water, supplying corresponding to the using amount at all times even when the using amount of hot-water becomes big while permitting the supply of hot-water quickly after starting heating even when the using amount of hot-water is big. CONSTITUTION: A hot-water storage tank device is constituted of a hot-water storage tank 1, a heating device 2, and a flowing device 3, conducting hot-water immediately above the heating device 2 to flow to the bottom of the hot-water storage tank 1 to supply it, while the hot-water storage tank 1 is formed so as to discharge hot-water to the outside from the upper part thereof, the heating device 2 is provided at a position higher than the substantially middle height of the hot-water storage tank 1 and is formed so as to control and heat water or hot-water above the heating device 2, further, the flowing device 3 is formed so as to send out the hot-water immediately above the heating device 2 to the bottom part of the hot-water storage tank 1 by a temperature difference between the temperature of hot-water in the upper part of the hot-water storage tank 1 and the temperature of the hot-water in the lower part of the hot-water storage tank 1.</p> |
