The Moulder Corporation solar-energy system provides space heating and hot water preheating for a single family dwelling located in West Greenwood, Indiana. The site has an array of flat-plate air collectors with a gross area of 704 square feet that faces 5.5/sup 0/ west of south at an angle of 45/sup 0/ from the horizontal. Circulating fans are utilized to transfer energy from the collector array to storage or directly to the conditioned space. Energy is stored in a rock bin containing 81,000 pounds of rocks and also in an 80-gallon water preheat tank. Auxiliary energy for space heating is provided by an electric heater, located in the space heating supply duct, if solar energy is not sufficient to meet the heating demand. Solar energy is provided to the hot water subsystem by circulating solar heated air through an air-to-water heat exchanger which preheats the water in the 80-gallon preheat tank. Auxiliary energy for hot water is provided by a standard electric immersion heater in the 52-gallon domestic hot-water heater. Performance data for August 1978 are presented and discussed.
