The solar air heater is near completion. Volume of the heater is about forty liters – 50cm x 800cm x 10cm.

I drilled fifteen to twenty holes on the cans at bottom row. And I drilled six holes per can to the rest, five at the bottom, one on top.







Indoor temperature was at two to three degrees. The highest temperature of outside was two degrees during the day.
