Solar Air Heater DIY
While browsing the Internet I came across this solar air heater, “heat grabber” from a 1977 issue of Mother Earth. My local Home Depot no longer carries the rigid foam insulation board manufactured by Celotex, trade-named “Thermax TF-610. (it was impregnated with glass fibers for strength and faced on both sides with heavy aluminum foil). Just the same, these plans show just how easy it can be to make your own home solar heater.
The plans are basically just two pictures which you print off at full size. Walking around the building supply store, I did notice the large foam sheets and aluminum soffit sheets. Maybe something similar can be pulled together.

Solar air heaters are amazing, especially in the northern united states. I’ve seen some estimates that a decent sized solar air heater could reduce home heating costs by 40% at todays fuel prices, that is a lot of money. I’m working on a program to get solar air heaters installed on low-income homes in New England.

I built a similar unit with plans form solarwindowheaters.com. We built 6 units and placed them together for maximum solar gain. Using the fan kit, we gain about 3,775 btu’s while the sun shine between 8:30 to 3:30.
