Homemade Solar Thermal Air Heater! This “steel downspout” solar air heater may be my best one yet. is easy to make, sustains hot temps (130-140F+) …has a 3 speed fan for extra temperature regulation, and the design allows for the addition of extra thermal mass (crushed aluminum cans (or even rocks) down the downspouts as examples). note this is the “standard length version” of the video. an “extended version” was posted 2 days prior. (both include “full build” instructions). if you like the vid. please rate, subscribe and share.
