A New Solar Air Heater for Quiet, Gentle Heat.

I like this idea and in theory it looks like it should work rather well. Here’s what Solar Infra Systems says about their SIS model solar heater:  It is like a room electric convection air space heater except it is operated by the sun’s solar energy. Hang or set it in a sun facing window, as shown (in the picture), or sideways, or even upside down, and it will maintain heat in a large room or area in the home. Its heating capacity is equivalent to a 150 to 500 watt electric heater, depending on the daytime sun and cloud cover. Sunlight operates a fan on the heater. The fan draws the room air into the heater and then pulls the air through metal solar energy collectors heated by the sun. The solar heated air is recirculated back into the room. The fan has a speed control so the air exchange in the room can be set, usually to 1 to 1-1/2 hours, at up to 75 cubic feet per minute. ---- Reading this description after the show makes me a wonder how big a room you can warm with the heating capacity equal to a 150 to 500 watt electric heater. 500 watts is not too bad. Most portable AC heaters at low use 600 to 750 watts and do put out a fair amount of heat. A salesman at the show told me the cost of Solar Infra System SIS Heater when it hits the big box stores will be $299.99.
