In a heat storage tank, a discharge port of an introduction passage is covered by a cup-shaped collision member constructed by a shield portion and a guide cover. In addition, a mixture protection plate having plural through holes is disposed in a tank body between the collision member and an inner surface of the tank body. Therefore, a high-speed water stream, upwardly injected from the discharge port, collides with the shield portion, and turns its flow direction by an approximately right angle. Thereafter, the water stream is guided by the guide cover to a lower side of the mixture protection plate. Accordingly, it can prevent water stored in the tank body from being mixed even when the injection water stream has a high speed.
