An instrumented single-family residence in Escondido, California, has approximately 1536 square feet of conditioned space. The domestic-hot-water (DHW) heating and space heating system has an array of flat-plate collectors with a gross area of 222 square feet. Solar energy is stored in a 750-gallon tank located in the ground floor utility room. Heated city water is stored in a 66-gallon DHW tank. A gas furnace provides auxiliary energy for the space heating system. An electrical heating element in the DHW tank provides auxiliary energy for DHW heating. Energy from a hydronic fireplace radiates directly into the living space and supplements solar modes 1 and 2. The fireplace-to-storage mode activates if the fireplace is being used and the temperature difference between its water plenum and storage output is more than 9/sup 0/F. During operation, water is circulated from storage through the fireplace heat exchanger. Original cost estimates are included.
