In an effort to get our new Oslo to burn better, I've re-done our chimney. I was using single wall pipe from the stove to the wall thimble, but in scoring some used 6" class A stove pipe I got a couple pieces of basic double wall for inside use. So my question is, what's the difference in surface temps between the two as measured by a magnetic thermometer?
With the single wall pipe I was always shooting for about a 300 degree temp 12" or so up the pipe, but what temps should I be shooting for with the double wall? Logic tells me 1/2 (i.e. 150-200 degrees should be good) but then again the clearances go from 18" with single wall to 1/3 of that (6") with double wall--so 1/3 the surface temp i.e. 100 degrees?? FWIW with between a 450-500 degree stove top temp, the double wall pipe is running about 180-200 degrees.
Thanks!
