PURPOSE:Not to disturb temperature distribution of hot water in a hot-water reservoir tank, by arranging a relatively large case formed with many holes and a relatively small case also formed with many holes in the hot-water reservoir tank in the manner that the relatively small case is located inside the relatively large case, and feeding hot water from a heat collector to the inside of the inner case. CONSTITUTION:An outer case 1 made of a plate formed with many holes and an inner case 2 smaller than the outer case 1 and also made of a plate formed with many holes are arranged in a hot-water reservoir tank 5, in the manner that the inner case 2 is located inside the outer case 1. A return pipe from a heat collector, having a T-shaped top, is inserted into the case from the top end thereof for feeding hot water returned from the heat collector to the inside of the inner case 2. Since, by employing such an arrangement, hot water returned from the heat collector is delivered to such a layer of water in the tank having the same temperature as that of hot water returned from the heat collector, it is made unnecessary to agitate hot water in the tank 5 and to lower the temperature of hot water near the water surface. Further, re-heating of water is rendered umnecessary, so that the system can be run economically. Further, it is also made unnecessary to agitate hot water in the tank 5 and to raise the temperature of water at the bottom of tank 5. |
