DOI:https://doi.org/10.2172/5546599· OSTI ID:5546599

The solar energy system at the First Baptist Church in Aberdeen, South Dakota is described. The solar energy system was built into the new 12,350 square foot church to heat the church and to provide domestic hot water. The 1404 square foot collector array of Solaron double glazed, flat black, flat plate collectors is mounted to the roof at a tilt angle of 30/sup 0/ from the horizontal. Thermal energy is stored in an 1100 cubic foot rock box that is located underground beneath the church. The box is filled with 35 tons of cleaned, washed rocks ranging in size from 3/4 to 1 1/2 inches. Solar space heating is provided by either the collector array directly or by rock box. Auxiliary space heating is provided by a 1,375,000 Btu electric boiler. Domestic hot water is preheated through a coil in the collector supply duct and stored in a 120 gallon tank. Auxiliary heating of the domestic hot water is provided by a 119 gallon electric water heater.
