  • You will increase heat output with turbulence in air stream, create little propeller shaped pieces out of the can bottoms you cut out and insert them about every 3rd can joint and you will see increase in output. I have a 4x8 panel and it puts

    out 143 degree air from 65 degree input air with a 160 cfm fan which is 13,472 btu's per hour or 80832 in the average 6 hours it runs in January per day which equals about 160% efficiency. May sound unreal but my heat bill dropped by half with 1 panel

  • I am working on another one for the roof. I have had some success with just making the holes in the can smaller!

  • We have about a 2000 square foot house. We heat with a wood stove and this solar furnace. I have only used my gas furnace for about a week when the temps got below 0. The solar works well on sunny days between 10 and 2. But it only helps in the living room at this point.

  • Thanks for sharing this with us! I bet the neighbors hate it!

  • first need well insulated house. second use heat exchanger method input air get in from inside of your house and cooked in heater increase temperature than go to the room again insides hot air go to the heater and cooked so efficient ,if use out sides cold air intake so heat loss will be high.

  • @funwithjamess are you supposed to put the steel wool in every single can ..like fill up each can?

  • is you box hooked up to a thermostat if so how did you do it im almost done with my box im stuck on the thermostat hook up

  • Roof mounting looks like a winner

  • Hey i just read your comment about poor output on your heater and I wanted to point you to another video I found that uses a little different design. Look up richallenmusic's channel. He has built several different variations of heaters and has built one that produces over 220F on a 43F day! check it out....hope that helps.

  • Nice work man.

    Congrats.
