Abstract:
1. A thermal energy storage system, comprising: a first tank for holding a quantity of water; a second tank having a quantity of thermal energy storage material disposed therein, the thermal energy storage material comprising a substantially solid material having a melting point above 32 degrees Fahrenheit (F), and a latent heat of fission approaching that of water; and recirculation piping connecting the first and second tanks, the recirculation piping being in fluid communication with an inner volume of said first tank, the recirculation piping further comprising a heating coil disposed within the second tank; wherein heated water disposed in said first tank at a first time is movable within said recirculation piping, and through said heating coil, to transfer heat from the heated water to the thermal energy storage material disposed within the second tank; and wherein cool water disposed in said first tank at a second time is movable within said recirculation piping, and through said heating coil, to transfer heat from said thermal energy storage material disposed within the second tank to the cool water.
