PURPOSE:To simplify the mounting work and improve the heat collecting efficiency by a structure wherein circulating pipes for connecting a heat collector and a hot water storage tank are arranged and fixed on the back of a frontal plate fitted to the front of frames in the natural circulation type water heater utilizing solar heat. CONSTITUTION:A plurality of the pipes 8 are formed upward and downward integrally or otherwise with the frontal plate 5 by being arranged and fixed on the back thereof by blow-molding or the like. And the heat collector 1 and the hot water storage tank 2 are placed on both the roof surfaces over a ridge 3 respectively and connected with each other by means of the frames 4 and then the pipes 8 are coupled through flexible pipes 9 to the water pipes 6 and 7 of the heat collector 1 and of the hot water storage tank 2 respectively. After that, the frontal plate 5 is fitted to the frame 4. Due to the structure as described above, the mounting work of the water heater is facilitated as well as the heat collecting efficiency is improved, because the pipes 8 are covered with the frontal plate 5. |
