<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply system of high heat efficiency to solve a problem in which the temperature of hot water in a hot water storage tank is lowered as heat loss occurs by use of a heat exchanger and the heat exchange cannot be completely performed, when the water is heated by utilizing natural energy, and the hot water of high temperature produces hot water by heat exchange between water and water by a heat exchanger. <P>SOLUTION: The water is heated by utilizing a geothermal heat collector 1 and a solar light collector 101 as natural energy, and the heated hot water is directly stored in a hot water storage tank 102 without heat exchange, thus the nature-friendly hot water supply system can be provided. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
