Space heating and domestic hot water heating is provided by a solar energy system utilizing 954 square feet of liquid flat plate collectors for a 10,000 square foot, one-story office building, Blakedale Professional Center, in Greenwood, South Carolina. The system was installed concurrent with building construction and heats 4,440 square feet of the building. The collectors are roof-mounted in three banks on wooden, sawtooth type supports with aluminized mylar reflectors on the back of the supports. The collectors are double-glazed with tempered glass and have copper absorber plates and a non-selective black coating. A drain down system protects the collectors from freezing. A 5,000-gallon steel storage tank, covered with polyurethane insulation, is buried underground approximately 50 feet from the building. A heat pump is operated downstream of the solar heating coil in the warm air duct to provide auxiliary heat. An electric resistance coil in the duct is also furnished for additional heat when required. Service hot water is heated by a single-wall tube bundle heat exchanger immersed in the storage tank and is backed up by a 40-gallon electric water heater. No heat exchangers are utilized between the collector, the storage tank and the solar heating coil in the duct. The piping for the system is galvanized steel, and the collector fluid is treated with corrosion inhibitor.
