PROBLEM TO BE SOLVED: To provide a hot water storage tank preventing a temperature gradient of a temperature interface layer between high-temperature water and low- temperature water in a tank body from decreasing even if the tank is used for a long time. SOLUTION: The hot water storage tank 11 stores high-temperature water H and low-temperature water L at the same time in the tank body 11A. A partition 21 preventing mixing of the high-temperature water and the low- temperature water is provided in the tank body 11A and has a sealant 23 for closing clearance between the interior wall of the tank body 11A and the partition 21. |
