<p><P>PROBLEM TO BE SOLVED: To provide a hot water storage type water heater effectively using hot water stored in a hot water tank by suppressing the lowering of takeout temperature of the hot water from the hot storage tank even if a large amount of hot water is supplied to a hot water supply destination all at once. <P>SOLUTION: This hot water storage type water heater is provided with a hermetically closed type hot water storage tank 1 and a heating means H for heating the hot water in the hot water storage tank 1 so as to be stored in a state forming a temperature stratification. This hot water storage type water heater is so constituted that the plurality of hot water storage tanks 1 whose upper parts in the upstream side and lower parts in the downstream side adjoining in the flowing direction are communicated and connected in series to each other, a water supply passage 3 is connected to the lower part of the one in the uppermost stream side, and a hot water supply passage 5 is connected to the upper part of the other in the lowermost stream, so that the water is supplied to the uppermost stream hot water storage tank 1 by the water supply passage 3 and the hot water in the hot water storage tank 1 in the lowermost stream side is supplied in a form of takeout by the hot water supply passage 5. <P>COPYRIGHT: (C)2004,JPO</p> |
