A water impervious liner tank is mounted against the insulation. A top rests on the contents of the tank. At least one insulating barrier extends down from said top to a point adjacent the bottom of said tank, the barrier dividing said tank into portions. Heat storage material substantially fills the tank. The heat storage material has sufficient voids to permit circulation of heat transfer liquid. A hot liquid intake pipe extends adjacent to the bottom of the tank in the center portion. A cool liquid out-take pipe extends adjacent to the bottom of said tank in a side portion. A heat exchanger is located in the upper center portion of the tank.
