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.
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
With 143F your losses to the outside air will be huge. The propellors will create massive resistance to airflow so your fan wont be delivering 160cfm, the outlet temperature is indicative of a much lower flowrate. If you measure the airspeeds of the inlet and outlet you`ll see a big difference.
Im going to make a new one and Im using aluminum beer bottles cutting 1 1/4 hole in the bottom takes around 200 the aluminum is heavier so I should get better results. and then Im building one more using 10mm coroplast making it 4x8 no cans in this one the air blows through the material and we will see
I was told to put in some stainless steel wool this will slow down the air and the stainless will obsorb heat helping to increase the heat out put I have a can system 4x8 and it works ok using 1/4 in inch glass and 2x8 material I found it very heavy and that was without the glass it must weigh near 300 pounds Im getting about 106 on a 39 f day its not satisfying me so I ask someone that has a lot of knowelge and he suggested the stainless steel scrub pads or brass or aluminum,
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.
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.
Nice heater, good luck with it. If you insulated the area where you suck out the heat you will have less heat loss though the glass. What size fan did you use?
Thanks for sharing this with us! I bet the neighbors hate it!

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

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

Where in Indiana are you. I'm 1/2 hour south of Valpo and am finishing a passive solar house. it would be cool to trade notes.
