A sensible heat storage method for use in conventional buildings with basements is disclosed that permits the long term storage of solar energy at reasonable efficiency in amounts appropriate for home heating. An exchanger consisting of a plurality of closely spaced, small diameter parallel or serpentine tubes with suitable manifolds is constructed on the central portion of the basement floor. The exchanger is covered with a layer of fine gravel, followed with a layer of waterproof insulation. Finally a second floor is supported on studs resting edgewise on the original basement floor. Horizontal conduction heat losses are reduced by allowing a peripheral margin, insulated from above, about the exchanger and by using a flow reversing system that maintains a horizontal temperature gradient within the exchanger.
