Build an inexpensive solar heating system the author s 240 square foot 30 solar collector is simple and effective.
This is part of a program to test several solar air heating collector designs for performance.
Drill 55mm 2 16in diameter cut outs on one side of the intake exhaust box.
The air around the absorber warms expands and rises creating a convection current.
