PURPOSE:To make the effective use of heat released from a hot water circulating hose and to enable a heat collector to be fixed to a hot water storage tank at a desired angle by a method wherein in the natural circulation type solar water heater provided with the heat collector and the hot water storage tank, the bifurcated sections at one end of a water circulation hose are connected to a water circulating nozzle and a hot water circulating nozzle, respectively, of the heat collector while the other end of the hose is connected to a water circulating nozzle of the hot water storage tank and a hot water circulating pipe is passed through the water circulating hose. CONSTITUTION:One end of a water circulating hose 5 is connected to the water circulating nozzle of a hot water storage tank 1 and the other end is divided into two parts of which one is connected to the water circulating nozzle 7 of the heat collector 2 while the other is connected to the hot water circulating nozzle 8. Further, the hot water circulating pipe 6 is passed through the hose 5 and one end of the pipe 6 is connected to the hot water circulating nozzle 8 of the heat collector while the other end opens in the tank 1. With the above structure, the water in the tank 1 flows into the heat collector from the nozzle 7 after passing between the hose 5 and the pipe 6, is heated by the heat collector and returns to the tank 1 from the nozzle 8 through the pipe 6. As a consequence, when the hot water is circulated, the heat released from the pipe 6 is collected by the water flowing through the hose 5 which is in contact with the outer surface of the pipe 6 without any loss of the heat and further, the heat collector can be arranged at a desired angle with respect to the hot water storage tank 1 since the hose 5 and the pipe 6 are arranged concentrically with each other. |
