This Simple DIY Video shows How to make solar hot air collectors at home with simple materials, these are made from old light fixtures, uses glass, surplus foam board and used metal siding. After these collectors are installed we will have a blower fan to force cool air through a manifold system from the the house into the bottom holes. The hot air being forced out the top will be channeled to different rooms of the house. The blower motor will have a thermostat to come on only when there is enough heat produced within the collector. A second thermostat will control the maximum temp. so the house does not overheat.
