    SunnyTherm® designer, Gary DuC​hateau, has a background in construction management, manufacturing, equipment design, and business administration. Years of living in a rural area with brutal winters made him acutely aware of the cost of heating and the unreliability of utilities in some areas. He and his neighbors often struggled with huge propane bills.

     These experiences, and a strong desire to find an eco-friendly affordable alternative, led Gary to experiment with various alternative means of heating a home, shop, office, greenhouse, cabin or other structure. The result was the design for the SunnyTherm® solar air heating system.

"We still, after 3 years have not purchased any new propane. As long as the sun is out, our 1,300 sq. ft. home is toasty. The solar furnace runs way past dark. Glad we put the extra in."
