Solar heating system

In a structure having a roof, an interior area and a wall which receives solar energy from the sun, a solar heating system comprising:

• a solar collector means enclosing a heat absorbing medium and including a transparent structural facing disposed in spaced relation with an absorber plate;
• said solar collector means being affixed to the wall of the structure for receiving solar energy and for transferring said solar energy to said heat absorbing medium in the form of heat;
• a heat storage plenum means for selectively absorbing heat from or transferring heat to said heat absorbing medium;
• said heat storage plenum means communicating with said solar collector thereby providing a first passage by which said heat absorbing medium can enter said heat storage means;
• a radiator means having first and second opposed ends forming the ceiling of the interior area and communicating with said heat storage plenum means at said first opposed end for providing a second passage for said heat absorbing medium and for transferring heat from said heat absorbing medium to the interior area of the structure;
• an insulation backing for said radiator means to prevent heat loss from said radiator only at the surface thereof opposite the exposed interior ceiling and disposed toward the roof;
• a duct means communicating with said radiator means at said second opposed end for providing a third passage for said heat absorbing medium between said radiator means and said solar collector means and for providing a fourth passage for said heat absorbing medium between said radiator means and said heat storage plenum means;
• said heat absorbing medium being completely enclosed and thus having a plurality of flow paths through said solar collector and said first, second, third and fourth passages;
• and
• a damper means for selectively altering said flow paths of said heat absorbing medium.
