Passive solar hot water heater. Final report

Technical Report ·
OSTI ID:6709943
This study involves the design and testing of a passive solar hot water heater. The primary goals are to achieve freeze protection without having to resort to antifreeze, manually operated shutters, or the use of mechanical aids. The objective was to test the heater under severe winter climate conditions. Data is presented to demonstrate that such a hot water heater can operate effectively in freezing climates. The hot water heater developed and tested in this study utilized Teflon as a multiple glazing in a unique upside down collection system. Heat loss is minimized in such a design, and manual operation is avoided. Performance results indicate that such a system also obviates the need for freeze protection.
