My first solar furnace. Everything did not go exactly as planned but it works none the less. If I wanted to run a meager 100 cfm fan the temperature readings would be higher, but I wanted to move some air to actually get some BTU’s into the house. Hope you find some useful information in this video. Thanks for watching. After running this solar furnace for a few weeks I realized that they are not worth the time and cost it takes to build them properly unless you have them track the sun. If you build a pivoting stand, buy a tracking circuit board, and an actuator this solar furnace will double the temperature of the air going into it for approximately seven hours a day during the winter, at about 300-400cfm which would probably knock about 25-30% off of your heating bill. The oven mounted stationary only performs really well for about 2 hours a day when the sun is pretty much directly in front of it. If your planning on building one, build a swiveling stand with it, and spend the $250-$300 for a tracking board and actuator to make it worth while.
