Whats the Best Pipe
I have a cathedral ceiling and am set up with the proper wall protection behind the stove, so I use I use 4 (2') sections of plain old black painted steel, single wall stovepipe. I have been using it for about 25 years (24 with coal) and replaced it once a few years ago when it began to show signs of corrosion. "...steel good since its cheep....." That is my philosophy.
