I'm (newbie) still in the planning stage of my Jotul 118 cb and prefab chimney installation, and I want to ask knowledgeable folks here if you think I'm ok with my plan. I've read as much as I can find here about drafting and chimney height, and I'm a bit concerned about overdrafting, as I'd prefer not to have to install some sort of chimney damper (and worse yet learn how to use it ....).

Here's my situation:
900 or 1000 sq. foot log house, 1 1/2 stories, open layout, not very tight and not insulated on walls (only on roof).
Chimney will go straight up.
Total planned height of chimney (measured from top of stove / bottom of stovepipe to top of chimney) would be 19' 4" give or take a few inches.
About 10 1/2 feet of the chimney would be above roofline (necessary because it's not coming up at the peak of the roof, and the roof is steep 45 degree)
I get a good breeze often from the North, the same side of the roof that the chimney is on (the gable sides of the house are east and west), which if I understand correctly means possibly more draft too.

Maybe I'm being overly concerned but I'd just like to plan as best I can. Thanks again for any thoughts.
 
You may be fine. I think most suggest pipe dampers if your over 30ft. You should have good draft at 20'. Even if you find your draft to be excessive, a pipe damper is no big deal to install or operate.
