A compact attic mounted solar heating pack assembly includes an enclosed sheet metal plenum fixedly hung by straps from the attic rafters at the apex of north and south facing roofing sections. An electric powered blower fixed to the plenum has an air inlet open to the attic interior below the south facing roof section. An air outlet of the blower opens directly to the plenum interior. A plurality of flexible ducts are coupled to respective air outlets within the plenum at one end with their opposite ends terminating in diffusers mountable within holes formed within the underlying ceiling for delivering air from the plenum chamber directly to the building interior below the attic floor. A first normally open cooling thermostat is mounted within the attic at the apex, beneath the south facing roof section. A plastic heat barrier is hung from the ridge pole and extends well below the plenum chamber to trap heated air within the section of the attic beneath the south facing wall. A second heating thermostat is mounted within the building interior below the ceiling and preferably on an interior partition wall and is series connected with the blower motor and the first attic mounted thermostat and connectable to a source of electrical current. The normally open thermostat closes when room heat is needed and the temperature in the attic is above 70 degrees to provide an effective independent supplementary heating unit for the building.

A compact attic solar heating pack assembly for mounting within a building attic having diagonally opposed south and north facing roof sections overlying a horizontal building attic floor forming the ceiling and defining an enclosed attic space above the occupied room space below the ceiling, said building further including vented eaves opening to the attic enclosure at the bottom thereof, said pack assembly comprising: a closed sheet metal plenum, means for fixedly mounting said plenum within said attic just below at said apex, a blower fixedly mounted to the plenum, said blower having an air inlet open to the attic enclosure, said blower including a blower outlet opening to the interior of the plenum, an electric motor for driving said blower, a plurality of air outlets within said plenum, flexible ducts coupled at one end to said plenum chamber outlets, respectively, and terminating at their other ends in diffusers, said diffusers being mountable within said attic floor and opening through the ceiling for delivering air from said plenum chamber to the interior occupied rooms of the building, a first, normally open, cooling thermostat adapted for mounting within said attic enclosure adjacent said apex and responsive to a substantial increase in temperature of the air within the attic enclosure over the outside air based on direct solar radiation through said south facing attic roof section, a second, normally open, heating thermostat adapted for mounting within the interior of said building below said attic and responsive to the temperature of the interior room, cable means for electrically connecting said blower motor and said first and second thermostats in series and adapted to energize said blower motor via a source of electrical power upon closure of said normally open first and second thermostats, and a blower outlet damper at said plenum chamber inlet for automatically closing off the inlet to the blower from the building interior via said flexible duct to prevent loss of heat from the room interior back through the attic.
