PROBLEM TO BE SOLVED: To provide a water feeding device for a high temperature water and low temperature water tank where a replacement work for a ball tap water feeding mechanism can be performed safely even when hot water feeding is being performed. SOLUTION: A high temperature water and low temperature water tank 20 is constructed such that it has a partition plate 21 at a central location where a large amount of high temperature water fed from a plurality of hot water feeding devices is stored in order to store a large amount of high temperature water for demand to a plurality of sites. In this case, a box member 27 installed in side-by-side relation with the high temperature water and low temperature water tank 20 is provided with a ball tap water feeding mechanism 26 having a water level detecting ball 26a and a water feeding port 26b, and then the box member 27 and the high temperature water and low temperature water tank 20 are communicated to each other through a communicating pipe 30 in such a way that they may show the same water level from each other. Further, in this case, it is desirable that the box member 27 is made of transparent material and a level plane is engraved at a position in the inner wall of the box member corresponding to a set water level H in the high temperature and low temperature water tank 20. As the hot water feeding device, it is satisfactory to employ a hot water feeding device in which discharged gas of high temperature recovered by a latent heat recovering system or the like is applied as a heat source to generate hot water, the hot water is circulated to cause fed water such as tap water or the like to be heated up to hot water and then the hot water is fed. |
