PROBLEM TO BE SOLVED: To separate gas such as dissolved air from a heat medium on a circulation path side, and simplify pipeline connection of a heat medium tank.SOLUTION: A heat storage system includes: a heat medium tank (heat storage tank 4) storing a heat medium (hot water HW); a heat medium circulation path (circulation path 6) taking out the heat medium (hot water HW) on a lower layer side from the heat medium tank, and returning the heat medium after heat exchange to the heat medium tank; and a gas discharge part (branch part 16) discharging gas (air), separated from the heat medium in the heat medium circulation path, to the lower layer side of the heat medium tank with respect to the heat medium circulation path. The heat storage system discharges gas separated on the heat medium circulation path side to the heat medium tank side. |
