Abstract
In a heat storage tank, an elbow pipe member defining a water introduction passage is formed by connecting an inlet-side cylinder portion and an outlet-side cylinder portion to have a corner portion. A step portion is disposed in the water introduction passage around a position where center lines of both the cylinder portions are crossed with each other. The step portion has a collision surface that is set to cross with a line parallel to the center line of the inlet-side cylinder portion, so that water introduced from the inlet-side cylinder portion collides with the collision surface of the step portion.
