PURPOSE:To enable supply of a required amount of hot water in a short period of time, by a method wherein an oil tank is located at the inside of a heat collector, oil, circulating in the oil tank, is heated to a high temperature by means of a heat- changed panel mounted at the heat collector, and water is heated through the utilization of the heat. CONSTITUTION:An upper surface of a heat collector 1 is densely covered with large-aperture lenses 2 and small-aperture lenses 3, and a water tank part 9, a heat- changed panel 4, and an oil tank part 5 are positioned in order from blow in the heat collector 1. Oil is fed through a feed pipe 6 into the oil tank 5, and heated oil is fed to a heat accumulator (not shown) through a discharge pipe 8. The heat- changed panel 4 is located in focus positions of the large-aperture and small-aperture lenses 2 and 3. Water is fed to the water tank part 9 through a water feed pipe 11, and hot water is discharged through a hot water discharge pipe 12. In this constitution, the solar heat is absorbed by means of the heat-charged panel 4, and when the oil 7 is increase in temperature through the thermal conduction of the heat- charged panel 4, water 10, simultaneously, is heated to a high temperature at an accelerating speed. As a result, a required amount of hot water can be supplied in a short period of time. |
