Solar Thermal air heater! Easy DIY. this vid. is an overview of my latest solar air heater. the design uses an “air channel” design to force the air to travel a route well over 12 feet inside of the collector. as the air rises it’s heated to well over 150F. (tested w/outside temp in low 50′s). no metal cans needed for this one (but optional aluminum flashing strips can be added to further increase temps). *or for the reuse/recycle option, try crushed aluminum cans along the channel. air is pulled out of collector by a small thin case fan …and is run using a small solar panel (3 to 5 watt panel being the optimal size). the collectors surface area is roughly twice the size of any i’ve made so far (but it’s super-slim design still keeps it lightweight). *the full video (posted 3 days prior) with full “detailed building instructions” can be found on my youtube channel video page. couple of things: i designed the collector to be able to pull air from outside or inside. to pull air from inside home just hook up a second vent pipe onto the air inlet at the bottom and feed both tubes in. also note; due to the collectors slim design i used a very thin case fan to allow for proper airflow. (if you want to use a standard 25mm style case fan, consider using 2×3 or 2×4 lumber for max. airflow (and adjust the internal dowel sizes accordingly).
Friends, Happy to introduce 2 DIY Solar Water Heater systems which are homemade. First is a easy method using tubing. Another is using a solar panel with heat storage and distribution. The designs are explained to You.

(This can be a science project, However, take caution to have a professional electrician and engineer to help You build it. Take note of safety.)
2. Smaller Coils Used

Smaller version is also good, have a fun time trying out.
