The Helio-Thermics Inc. House Lot No. 8 is one of two instrumented single-family residences in Greenville, South Carolina. The home has approximately 1086 square feet of conditioned space. Solar energy is used for space heating and for preheating domestic hot water. The attic space is used as the solar energy collector. It has a 416-square-foot aperture and is painted black inside to maximize absorption. Warm air accumulates in the peak of the attic roof and circulates through the conditioned space or through storage by an air handler. Heat is stored in an 870-cubic-foot rock bin under the house. Cold water is preheated in the attic by thermosiphoning water from the 82-gallon preheat tank through a manifold system of copper tubes. These tubes are attached to black sheet-metal plates to enhance absorption. Preheated water is stored in the preheat tank and supplied on demand to a conventional 80-gallon domestic hot water tank. Freeze protection is provided for the liquid collector by drain down. Auxiliary space and water heating are electrical. The system has 8 modes of operation: collector-to-space heating; collector-to-storage; storage-to-space heating; auxiliary energy-to-space heating; summer mode, space cooling (outside air circulated through the living area); summer mode, passive cooling storage (in the attic and in the rock bin); summer mode, storage-to-space cooling; and domestic hot water preheating. The instrumentation for the National Solar Data Network is described briefly. Original cost estimates for provisioning and installation of the solar system, with the exception of instrumentation costs, are given. (LEW)
