Solar air heat is a supplemental space heating system, using solar air heating collectors to turn energy from the sun into warm air for businesses and homes. When the sun is shining, and the building is calling for the heat, the system turns on and a fan delivers it. The system shuts down when the building is no longer calling for heat or the sun is not out. Used correctly, solar air heat can reduce your heating bills considerably for decades.
Unlike a solar PVC system, solar air heating panels are mounted vertically on south-facing walls (where solar exposure is greatest), so the aesthetics of the building is not changed. Fully automatic and easy to use, the only control you ever need to adjust is the solar thermostat. You simply turn your solar thermostat on during the early heating season and turn it down when warmer weather arrives. The filters need to be changed annually, but that’s the extent of the maintenance.
