<P>PROBLEM TO BE SOLVED: To improve heat reserving performance of a heat accumulating tank for storing liquid by reserving heat. <P>SOLUTION: This heat accumulating tank has an inner cylinder 81 having a storage part 811 for storing the liquid and having an opening part 812 in a lower position of the storage part 811, and blocks up the opening part 812 by a body 84 for forming a liquid inflow passage 841 and a liquid outflow passage 842. When an inner diameter of the inner cylinder 81 is set to a tank inner diameter D and the vertical directional length of the storage part 811 is set to the tank height H, D/H≤0.5 is realized, and the storage part 811 becomes slender in the vertical direction, and a distance between the body 84 being a main heat radiating part and a high temperature water area (the upper end vicinity in the storage part) becomes long, and the high temperature water area vertically expands. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
