Single wall stovepipe

As some of you know I have a new install coming up in the next couple weeks and tonight I was thinking of single wall pipe from the stove to the chimney. I have some standard black 24 ga. pipe.
My question is for something different than what I have, to include metal thickness too. Does anyone have non typical single wall pipe, maybe like a welded seam type pipe in maybe 20 or 22 ga? I think I'm just looking for a heavier gauge pipe that looks less generic

 

Can't add much to the post other than to say that single wall pipe throws a lot of heat. I'm using double to stainless and it still gets burning hot. Good luck with your search.

 

Went from single wall to double wall.
My catalytic stove works better on low with double wall.

 

Look up Rigid Stainless Steel Chimney Liner Pipe. Some people use it for a "permanent" stove pipe because it lasts many times longer than black stove pipe, plus it has welded seams.

I seriously considered it with the IS but decided on double wall stove pipe instead.

 

Stove shop I got my stove from does double wall , no single. Need to keep that heat in the flue.

 

Brian, what made you decide on double?

 

Dave, I'm assuming you tried single wall at one point and settled on double because of better performance? If that is the case I want to do this once. Never had a Cat before so I never took your reasoning into account.

 

I use 24 ga black stove pipe sealed at all contact joints with high temp silicone. Last year was the first time I'd ever sealed the joints. When I'd stand next to the Old Mill stove I had before (pipe not sealed) ... on a windy day, it was nuts how much air was being sucked from all of the pipe joints. Really bad. When I bought the Liberty, I knew it had to have a decent steady draft or it would do odd stuff. With the sealed pipe, it worked perfectly and windy days made no difference. No air leaks anymore. Now... getting the pipe off when I need to, is gonna be fun... ... but, with the bi-pass open, I think I can get to the pipe from inside the stove to inspect w/ mirror and clean.

We installed a double wall pipe at the cabin, on the outside, and one of the benefits is a tight joint fit because of the twist loc feature. I haven't sealed the cabin's 24 ga inside pipe yet, but I should as it has issues with it's draft.

 

Woodstock recommended it with this stove to keep the heat in the flue. It operates at such low flue temps they want to keep whatever heat is retained going up the flue, not radiating out into the room. With the Fireview I wanted that heat in the room. This stove has enough "extra" BTU output that I don't have to worry about scrounging BTUs from single wall stove pipe.

 

If you need to have the stove a little closer to the wall, 2x stove pipe will help with that.
I put single wall 22 g welded seam in about 4 years ago, but I went with 2x wall adjustable when I put in the 30NC. The inner pipe is stainless, I believe, and it's EXTREMELY easy to get installed. Put the pipe on the stove, slide up the outer wall to the Class A adapter, and shoot some screws. Except for the screws, it took all of a minute or less.
Easy on, easy off. It's pricey though.

 

I originally bought the Class A Selkirk chimney at Lowes. I took a print out of the prices at Menards in Ohio and they matched it, saved a good 20%.

Then when I installed the Beta IS I just bought the double wall Selkirk stove pipe kit from Lowes. Hooked right up, easy install, but I did have to cut the double wall vertical pipe due to the height of the top vent IS install.

 

That's why I got the adjustable Brian. No cutting required. This one adjusts from 30 something to 68". They make smaller pieces.
I used the Selkirk stuff as well. The only problem I had was that one of the Class A pieces was very slightly bent at the end, which made the twist-lock a bit tough to do. That piece is outside.
Some have said the Duravent and other stuff is made gooder. I have no experience with that.

 

Both the vertical and the horizontal in my kit were adjustable too but the vertical was several inches too long with the height of my Beta IS. I didn't want to go through the hassle of lowering the stove itself so I shortened the double wall pipe instead.

 

Thanks for the responses so far, plenty if gooder info that I can run with.
Next BIG question. In my pipe run from the stove I have 1- 22.5 deg elbow that is needed to make this come together. This morn I couldn't find any pipe companies that made them. Any ideas?

 

A lot of hardware stores here sell the adjustable 90s that can get to 22.5... if you're talking single wall. Double wall, don't know of any.

 

Woodstock has some nice welded seam pipe, custom painted if you prefer, for a very reasonable price.
FWIW, I'm using 8' of cheap single wall pipe without any issues. Draft is great, never a back puff or cat stall.
When the cheap stuff fails, I will go back with good single wall welded seam.

 

Yeah, that's the only option I could think of unless they made 22.5 in the rigid stainless chimney liner pipe. The double wall elbows are all rigid.

 

I'm sure one of the pipe company's must do it but I'm sure it's at a premium.
