Abstract Solar heat storage apparatus, invented by Thomason, includes a tank of water surrounded by a truckload of stones in a heat storage bin in the basement, U.S. Pat. No. 3,254,702 and others. Air circulating through the bin is warmed and circulated through the home to warm the home, or other building. The present invention adds humidity to the air and also enhances heat transfer out of the storage bin and into the home by heat-of-vaporization. That permits use of heat from storage to a lower temperature level while making the home feel warmer. And, the solar heat collector obtains more free heat from the sun because it is operating at a lower temperature level and more efficiently. Heat that normally goes up the chimney from an auxiliary heat source, such as a water heater or furnace, is used to assist home heating.
Heat storage bin apparatus and auxiliary heat apparatus comprising heat storage material in an insulated compartment having means to receive heat from an outside source and store it for use at a later time, combustion apparatus having a first flue pipe means for transporting products of combustion to a point outside of said heat storage bin, passing, in transit, in heat-exchange relationship with said storage bin to warm the air or other contents thereof at certain times, second flue pipe means to transport said products of combustion to a point outside of said heat storage bin substantially in non-heat-exchange relationship with said storage bin to avoid warming the air or other contents thereof during other periods of time, and means to direct the flue gasses through one of said flue pipes, or through the other.
