Directions are given for constructing a home-made solar water heater that is expected to supply over 50% of the hot water for a family of 3 or 4. System cost is estimated at $250.00. The system utilizes three 2 x 8-foot solar panels. Hot water from the panels is pumped through a preheat-storage tank where it heats domestic water. The preheated water is then drawn into the cold water inlet of the regular home water heater. The pump which circulates the fluid is controlled by a differential thermostat which turns it on when the solar panels become hotter than the water in the preheat-storage tank. The collector panel design, construction, assembly, and installation are described in detail, as are the heat exchanger and storage tank. A thermosiphon system design is also briefly outlined. Sources of necessary materials are given as well as a list of needed materials, miscellaneous supplies, and major tools. Finally, the research and experimental work leading to the design is described, including the testing of models. (LEW)
