Re: chimney/flue questions
Given that theory, (which doesn't make sense) then you could get a 12" pipe
up my flue. And the area of a 12" circle is over twice that of the area of
an 8" circle. AND the area of the 12" square is almost THREE times the area
of an 8" circle. So, believe me, a 12" flue makes a hell of a lot more
draft than that of an 8" pipe. This was confirmed when i finally dropped 8"
single wall pipe down my chimmey and hooked it directly up to the stove
insert. No more raging away when i open the doors.
but thanks for playing,
steve

the effective size of a square or rectangular chimney is the largest
circle that can fit inside, so your 12 inch square isnt as oversized
as you might bellieve
