Just curious. I have a one story ranch and want a cat stove (low flue temps). Thx.

There should be lots of us single story guys between 10 and 15. My cat stove exceeds the minimum requirement of 12' by a foot or two.
My kitchen woodstove (Napoleon 1900p) has a 22' flue at 6"id, while the living room Napoleon NZ3000 has a 16' flue at 7" id. Both are Class A insulated stainless. I DO get a better draw on the taller, smaller id flue. But they both work very well, no problems whatsoever.
12-13 feet and no issues here. Although I think I am going to add 2-3 feet when I upgrade my stove this spring
Vertical height above the stove top is 16 feet.................but that includes 2 back to back doublewall 45's right out the stove top.
Didn't cast a vote, because I'm 17'8" of verticle rise, but.. my flue pipe is a twisty snake, hardly ideal.
I will say, I added 4' of class A fairly recently, and it has been an improvement.
15' of straight up flue would be great, anything taller would only get better with a BK.
18', 25', 25'
22 ft here i was told by chimney chap
8 ft of single wall and 5 ft of duravent plus and does meet all codes and seems to draw fair but does make the air control on stove very sensitive. so not sure how that fits in your poll.
A 24' vertical run here with a hard 90 degree turn on it (which I understand reduces the effective vertical run by 5')gives 19 feet vertical. So I chose 20 feet. It takes the exhaust out of the stove and puts it outdoors OK.
8 ft of double wall and about 8 ft of class A.
15 foot run up the side of the house
2 runs in a single insulated stone covered chase 35'.
I voted 15'. Rear-vented into a tee, then 17' up from the stove top.
Been running about 12-13' of insulated SS liner straight up from the stove. But have been having a bit of trouble with smoke spillage on warmer and/or humid days, though the burn rate is OK. This year, I ran an experiment by adding 5' of cheap 6 inch metal furnace duct. Totally different stove. Smoke spillage is 100% eliminated and you can hear the air 'woosh' through the intake.
How should we measure our chimney height? From the ground up or should we measure the actual height from where it leaves the stove ?. I have an outside masonry chimney that has a clean out below where the thimble comes out from the house. Measuring from the outside would give a false reading of actually usable chimney.
Edit. It is Straight up
35'. Just constricted the doghouse air intake to accommodate the insane draft that I never realized was so excessive. Now the stove runs the right way.
Basement install in single story ranch,,26ft. on the outside.
15' straight up. Class A ceiling up, DSP double wall inside.
15 & 15.
Good draft on both.
Top of stove to the 'sky hole' is what mainly matters. So essentially the 'length of pipe'. Though I do see what you're getting at. My 'chimney' is probably close to 20' measured from the ground, but the draft is created only by the 'flue' going to this stove.
Never had measured it, but it's roughly 15ish ft.
