You are talking about class A doublewall insulated chimney pipe...you want double wall stovepipe for this...
I will measure my chimney down to the T, have been meaning to but time hasn't worked out lately. When we bought the house, the liner was cracked, so I had a chimney guy come and fix it. They put in metal, and poured some kind of concrete (I guess that's what it is/was) around it. There is a piece of single walled metal pipe sticking up out of the brick chimney..I think I have a pic to post, if not I will post one this evening. Not sure if I need to "do anything" with that piece of single that's exposed (for temperature /condensing reasons)?
All I've had was single wall in my basement (I think it's 24gauge). Probably 3' or so went from '10 to last year and still looked fresh. It got trimmed when I got the bigger Baker, then I bought a new piece for the England's because it was too short. I'm no expert either but it's been fine in my application. Definitely radiates heat too.
In my neighborhood singlewall (steel) lasts 2-3 years in the basement. I switched to SS when I put the Kuuma in...done.
Although you can get by with standard run of the mill single wall I prefer Selkirk double wall with a slip joint section for easy removal for cleaning and better heat retainage/draft. The 2x45's is also a great idea. Looks like you have a fairly short vent system overall. What is the vertical dimension from stove top to cap? Each 90 takes away 2 feet or so of vertical effectiveness. Something to consider with a single level setup. Woodstock specifies 15 feet of vertical venting from stove top to cap.
Yeah, that's why I've been meaning to measure, and will measure and post, the height. The floor of the stove room is pretty much ground level (closed in carport we think), so no crawlspace etc. Except for the short (brick height) hearth pad, stove is on the "ground".
I'm fairly certain it's single from when I've been up there before, but when I measure I will take a pic.
Got on the roof. Left phone in vehicle and it was last light, but pretty sure it's single. There was a faded sticker that I will go back up there to see what it says. From tip top of pipe (not rain cover) down to take stopped in bottom of T (or 90 I guess) is 10 feet 7 inches. Will measure from the T down to approx stove top later...
From hearth to the T is about 5 feet 8 inches. So I guess at best I'm at the minimum recommended height, then take away for 2 90s...or a 90 and 2 45s if I can make that work. Does horizontal run go into the equation? I have about 16-18 inches of horizontal, going from center to center of pipe (I imagine that will change some with the AS, and if I use 45s)....
Horizontal can work against you, but your run is pretty short so... but I'd still try to use 45*s if you can...
If I can get back on the roof in time tomorrow, I'll take a pic of that top piece of pipe, to see if anyone thinks I need to do something to it, or any recommendations. I haven't looked at any double wall pipe. Do you put screws in the joints? Also, do you need to seal the joint seams?
Floor of fire box to top of chimney, your total chimney height. Your chimney is on the short side like mine. Some of the advice you’ve received will off-set being short. I would use every piece of advice you get to help combat being short. If possible at all, move stove away from wall slightly, or more, to accommodate the 2-45* advice. Double wall stove pipe mentioned with stainless interior. Your new WS stove will throw plenty of heat into the home for you, and will do it better with double wall stove pipe and it will last. I just bought single wall and I am kicking myself. Go double wall stove pipe. It too will off-set being short. Insulate that top section somehow, to the top, if it isn’t already class A double wall. With the advice these guys have already given you, you do them all and you will be glad you did. Sit back, relax, enjoy, take pictures of the light show to post here. I am envious.
Is this good /decent stove pipe? Do you have to use the same brand pipe pieces (ie straight pipe, 45s, 90s)...do they only work /fit with same brand? I've never shopped for pipe, and not sure what I'll be able to find where...
Single wall can often times be mixed n matched (not always though...or at least not without some fiddling with it) but doublewall stove pipe pretty much needs to be same brand for everything...same with doublewall chimney pipe...
Getting some measurements before we go to town, hope to go by a place or two to see what I can find for pipe. At least see what um dealing with, or buy if they have what I think I need. A 90 vs 2 45s....I assume the 2 45s are longer than one 90, in terms of vertical height to attach to the T?
