  2. Theres one thing I think your missing convection I will be fun to see how
    your box gets the air from the channels I don’t see a top and bottom header
    as to your inlet outlet you have them the wrong way round but time will
    show you that if you get a chance take a look at all my videos ( solar
    heater uk) if you cant get 200f plus from your box look at my 4X3 box
    (cans) I have had up to 200f with an outside temp of 44f and lower mine is
    a work in progress a you will see yours is

  3. Then there is dense foam weather striping between the glass and frame, held
    in place with 1″ x 1” x 1/8″ angle held with screws. I can tell you this,
    if you took the foam out it would float. Did I say it was better than cans?
    I will have to look. I think what I said was it was WAY easier than making
    it with cans. As for better or worse, I really don’t think there would be
    any real difference.

  4. Those vents are a great idea. I’ve made one from 1.5 inch styrofoam house
    sheathing and wedged it into my window sill on the inside. I’ve used it
    that way for 3 years now. I’ve had temps high enough to start melting the
    styrofoam. It’s time to remake it. I have been wanting to make a box from
    some paneling I have.

  5. I have it open in the back for air flow, so no header needed. All you are
    trying to do is move air across the aluminum and transfer the heat. The
    aluminum is the same temperature on the front or back side. The air or
    aluminum doesn’t care which side it’s on. I can get it over 200 deg. F. if
    I restrict the air flow but that’s not what I want. We have had days in the
    20’s and still get 180+ air if the sun is shining.

  7. Hi from pete solar heater uk I can see your new to this it shows by the
    design flaws your building in to your box, first theres more air leeks
    every where on your box and before I see part 2 I bet you under do the
    insulation as to the ali with the folds being better than cans I think not

  8. Thank you for your input, I do appreciate any comments, it’s how we learn.
    That being said, I don’t know what you are seeing that I’m not. The corners
    are welded together. The back is a single sheet of aluminum that is pop
    riveted and caulked into place. Then there is 1″ foil backed urethane foam
    insulation that is again caulked at all seams.
