I built these hot air panels 3 years ago. They are 78" x 48" each and are identical. Double pane glass, polyo foil faced high temp insulation, boxer fans and snap disk thermostat. Flat black high temp stove paint covers the sheet steel absorber plates and baffels and aluminum trim covers over the glazing seal which is routered into the wooden 2x4 frames. These put out approx. 1000 watts in heat each in full sun and will easily heat 2 good sized rooms. They are heavy at well over 100 lbs each. I am only selling them to make room for solar hot water instead as I am upgrading my DHW to include storage to suppliment my heating. $400.00 for both if you come and pick them up. I am taking these down within the next couple days so they will be ready to load.
