<P>PROBLEM TO BE SOLVED: To increase frequency of supplying intermediate-temperature water from an intermediate-temperature layer of a hot water storage tank, in a hot water storage type hot water supply system for properly supplying the high-temperature water and the intermediate-temperature water. <P>SOLUTION: This hot water storage type hot water supply system 10 includes an intermediate/high-temperature water storage tank 11 for storing the high-temperature water and intermediate-temperature water together, a high-temperature water storage tank 12 for storing the high-temperature water, a heat source machine 13, a switch valve 16c for switching a hot water supply source of the high-temperature water between the intermediate/high temperature water storage tank 11 and the high-temperature water storage tank 12, and a control portion 14 for controlling the switch valve 16c. The control portion 14 controls the switch valve 16c so that the hot water is supplied from the high-temperature water storage tank 12 with priority with respect to the intermediate/high temperature water storage tank 11. Thus the frequency of supplying the intermediate-temperature water from the intermediate-temperature layer of the intermediate/high temperature water storage tank 11 is increased, and the energy efficiency can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT |
