- This is a test of my DIY passive solar heater. The box dimension is 2' x 3'. The heat exchange is simply 8 channels made from two 10' steel drip edges cut to 26" lengths painted black to absorb the solar radiation. The air is circulated through the box by a 92mm cpu fan powered by a 12v (300mA) solar panel.
