My stoves pipe runs directly out the back through a wall thimble to the outside. Am I missing out of some possible extra heat? I was under the impression, the less 90* turns in the run, the better the draft would be. But I can also understand how the internal black stove pipe would provide a little extra warmth. Not sure where the trade off is.
Can you check the pipe temp right at the thimble and see how it compares to someone's with the same stove, running at about the same temps, but with a longer pipe ?
Many of the older stoves with long internal flues, and longer runs of stove pipe, can get into the five to one ratio and higher, of the stove's hottest outside temps to the stack temps near the thimble. Not sure how close the newer stoves regularly get to that, but comparing that ratio to similar stoves would give you an idea of what yours can, or can't, do with more pipe.
