Solar Heater

Step 1 Frame and Fit

Make a box to mount on the wall of building (A south wall, SE and SW also can work.) This should be mounted vertically on a wall; the higher in the sky summer sun won't hit it as directly as the low winter sun. The walls of the box are 2x6 lumber; the angled "roof" of the box is a 2x8. I found it good to prebuild the box on the ground and then mount it to the wall. Make the box based on stud spacing in the walls; I have 24" studs, so my box is 8' wide with vents cut into four sections.

I sized the solar collector based on the numbers from the Mother Earth article where the guy built 160sq ft. of collector for his 700 sq ft building; using that ratio I built a 48 sq ft collector for my 200 sq ft garage.
