My goal was to use as much recycled and reclaimed material as possible.
The heat is fed into the enclosed porch. I open the house window and I have free heat in the winter.
In the summer months the sun tracks higher in the sky and the overhang of the roof prevents the sun from hitting the collectors.
Step 1: Trimming window panes
I used a circular saw and a straight edge and trimmed them to all have a uniform side, I made them about 1 3/4 inch.
Step 2: Building frames
Step 3: Fastening to wall
Step 4: Shoot it up
lay a bead of caulk on inside and outside. caulk in pocket hole pockets and prime.
Step 5: Paint interior
Next is to drill holes top and bottom for air to circulate. Touch up flat black paint around holes.
Step 6: Interior metal
paint all the metal flat black.
On the flat metal collector i have the metal suspended from cup hook attached to the top of the collector box. The dog food cans are glued to the back of the collector.
