The solar energy system for a new single family detached residence in Kirkland, Washington, preheats domestic hot water (DHW) and heats 2607 square feet of occupied space. The 546 square foot collector array was manufactured by Solaron Corporation. The collector back is insulated with fiberglass insulation batt, providing an R-12 insulation value. The collector mosaic is installed at a 57/sup 0/C tilt to the horizontal. These collectors utilize air as heat transfer media and require no freeze protection provisions. The air Thermal Storage Unit consists of a container filled with 27,300 pounds of smooth surfaced stones of 1 to 1 1/2 inch average diameter. The total volume of storage container is 273 (6' x 6' x 7'7'') cubic feet. The container has concrete walls and bottom which are insulated with preformed styrofoam panels. The 11 cubic foot water storage tank has fiberglass insulation. Service hot water is preheated by a heat exchanger coil installed in the air duct from the collectors to the air storage. Space heating is provided by air circulation using collectors, storage bin and gas-fired furnace. An Air Handler Unit controls overall air flow in the system. (MHR)
