    • Using Sand to Store Solar Energy -

    2011-4-11  Thermal storage. If my fuzzy math is correct, 180 tons ( 360,000 lbs. ) of sand storage at .19 Btu per lb. per degree F yields 68,400 Btu's of thermal storage per degree F. This amount of thermal mass (180 tons) is a lot but is in no way sufficient to store a season's worth of heat

    • Solar Heating with Sand Bed Heat Storage

    2018-11-15  These homes use a concrete slab with a compacted sand bed under the slab for the storage of solar heat. The sand bed typically extends under all of the house and is typically about 2 ft thick. The sand bed and slab provide a large mass for storing heat. The sand bed outer edges and bottom are insulated to prevent heat loss to the outside.

    2010-7-11  This strikes me as a ‘shooting from the hip’ approach. In addition, when designing a sand bed for heat storage and redistribution it is probably recommended to have a back-up heat source. The back-up heat source will likely be sized to meet the design heat load and that becomes second redundant heating system and additional expense.

    • WHY WE ARE NOT USING A SAND BED TO STORE

    2011-12-20  Yes there is air in sand, but the idea is that you are trying to store heat by radiating it into the sand particles, so the depth of the bed will slow down the rate at which your room will warm up even from the upper loop. A sand bed is exceptionally unresponsive. You can’t crank up the thermostat and get more heat
