摘要 <p><P>PROBLEM TO BE SOLVED: To provide a solar heat hot water supply system that efficiently collects solar heat for energy saving. <P>SOLUTION: A controller 10 drives a circulation pump to start a heat collecting operation when a temperature difference (Tm0-Tw0) between a heat collector-side heating medium temperature Tm0 and a water supply temperature Tw0 is equal to or larger than a predetermined starting temperature Tn0, and controls the number of revolutions of the circulation pump P during the heat collecting operation so that the amount of collected heat, which is supplied to a hot water storage tank 2 and found from the product [(Tin-Tout)×V×C×d] of the temperature difference (Tin-Tout) between an incoming heating medium temperature Tin and an outgoing heating medium temperature Tout, a heating medium flow rate V, the specific heat C of the heating medium, and the specific gravity d of the heating medium, is larger than the power consumption needed to drive the circulation pump P. <P>COPYRIGHT: (C)2012,JPO&INPIT</p>
