The Fauquier High School Solar Heating System utilizes a solar collector array of 2415 square feet active area. The collectors are mounted in a single plane which is tilted at a 53/sup 0/ angle from the horizontal. The latitude of Warrenton, Virginia is 38.6/sup 0/. Thermal storage is provided by water stored in two concrete tanks, each of 5500 gallon capacity. The tanks are insulated with 4'' of polyurethane and have a temperature loss of 1/sup 0/F per day at a temperature of 140/sup 0/F. Piping to the tanks is arranged so they can be used separately for maximum efficiency. A drain-down mode is used to provide freeze protection for the collectors. No antifreeze is used in the system. There are no heat exchangers in the system except for the classrooms where two water--air convectors are used for space heating. The convectors are equipped with a two speed fan and are sized to provide the heating requirements of the classrooms with 100/sup 0/F water storage temperatures. Back-up heating is provided with the electric resistance heaters originally installed in the classrooms. One classroom has, in addition, an oil heater. The operation, performance, maintenance, and modifications to the system over the 1974-75 and 1975-76 heating seasons are reported in detail. (WHK)
