Solar air heater

Putting one layer of cardboard to insulate

Installing radiant barrier to increase insulation

I used a washer and screw to secure the insulation materials.

It was first operation of the solar air heater. It’s fully functional now.

Checking air temperature

Twenty three Celsius degrees at the heater pipe

Seventeen Celsius degrees near the pipe hole

Five Celsius degrees near the ceiling

Outside temperature was four Celsius degrees.

Concrete brick crusher

I bought a heavy duty hammer head from a scrapyard few months ago.
