They depend on the barometric on the oil burner to limit draft when operating their coal stove. I'm sure running a T straight down a few feet would have minimal impact on the barometric's performance. Although I don't have any desire to do so since my furnace is a basement installation. Don't be afraid to think outside the box. If done safely, It's how progress is made....
People may be getting away with that, but it's not an idea setup.
Seems like much ado about nothing anyway. How much cooler is the air at the floor than 3 feet up? A couple degrees?
I can lay my hand on the stack after the baro and hold it there all day. I doubt a couple degrees is going to make much difference.
The problem with all this mental masturbation is that every situation is different and results from one set up might be totally in left field for another.
I run mine with foil over the baro in the early and late season because my chimney has minimal draft. As long as the wind doesn't pick up, I don't see where I'm "wasting" any coal. I tend it twice a day regardless.
The only wasted coal comes from not being able to idle the stove low enough and having to open the windows to let the heat out.
