<P>PROBLEM TO BE SOLVED: To provide a storage type hot bath water supply apparatus that efficiently performs additional heating of bath water while boiling water. <P>SOLUTION: The storage type hot bath water supply apparatus includes: a heating return pipe 10 returning high temperature water heated in a heating means 3 to the upper part of a hot water storage tank 2; and a bath heat exchanger 19 set at the upper part in the hot water storage tank 2 and heating the bathtub water by heat exchange with hot water in the hot water storage tank 2. A discharge pipe 44, communicated with the heating return pipe 10 and suspended to the lower part of the bath heat exchanger 19, is provided. A first discharge port 45 intensively feeding the boiled high temperature water directly to the bath heat exchanger 19 is provided, when there is no high temperature water in the bath heat exchanger 19 part, at a position where the discharge pipe 44 faces the bath heat exchanger 19. Further, a second discharge port 46 discharging the boiled high temperature water into the upper part in the hot water storage tank 2 is provided, when there is high temperature water in the bath heat exchanger 19 part, at a position of the discharge pipe 44 above the bath heat exchanger 19. Thereby increasing the efficiency of the additional heating while boiling water. <P>COPYRIGHT: (C)2012,JPO&INPIT |
