PROBLEM TO BE SOLVED: To provide a heat exchange tank and a heat exchange system, which can efficiently produce hot water, particularly hot spring water by using steam and which facilitates a maintenance, and to provide a heat exchange tank and a heat exchange system with an inexpensive cost for manufacturing and installing.SOLUTION: A heat exchange tank includes: a heat exchange tank body 101 enclosed by a bottom plate part and a side plate part; a water feeding pipe 200; a steam transporting pipe 300; and an outflow pipe 400. The heat exchange tank body 101 includes: a first reservoir 101A for temporarily reserving supplied water Wfrom the water feeding pipe; a heat exchange chamber 100B where steam Sfrom the steam transporting pipe is supplied to the supplied water moving from the first reservoir and passing over an overflow wall 140 to a downstream side to exchange heat to produce hot water; and a second reservoir 100C for temporarily reserving hot water Wmoving from the heat exchange chamber and passing over an overflow wall 150 to the downstream side, and allowing the reserved hot water to flow through the outflow pipe to the outside of the heat exchange tank body. A steam ejecting pipe 320 mounted at the top end of the steam transporting pipe is disposed in the heat exchange chamber 100B to eject the steam Sthrough each steam ejection hole 321 into the supplied water Win the heat exchange chamber. |
