Thickest single wall stove pipe available?

[tlhfirelion]

As I work towards redoing my hearth and stove, I will be replacing my single wall interior pipe. I currently have the thin, cheap stuff from Lowe’s. Are there any really thick single wall pipe options out there? I found some 20 gauge pipe by AllfuelHST but figured I’d ask the hive here since y’all have more knowledge on this stuff than I do! Lol

Thanks!

Just get double wall.

Thanks for the reply. What would be the reason to do so? I have it for the ceiling penetration and exterior.

You probably have “Class A” for the exterior. The stainless shiny stuff. It gets confusing because class A is double wall in effect. But class A has ceramic insulation in between the walls. If you think you have something other than Class A for your exterior, feel free to post a pic a one we can tell you if looks proper.
Interior, “ double wall” (which will be black color), is better for insulation of inner pipe, which gets you less creosote and gives you closer clearances. This interior double-wall pipe does not have insulation in between walls other than air.

Double-wall stove pipe is not the same as the shiny class A chimney pipe. It is only to be used in the room envelope and connects the stove to the chimney. The inner liner is stainless and it has 6" clearance instead of 18" for single-wall. Double-wall stove pipe will keep the flue gases hotter for a cleaner, better drafting flue.

Ahh, yes, ok, makes sense. Any brands you would suggest? Does it need to be the same as the exterior pipe I have or are the connections universal so to speak? Thanks for the help.

Understood, thank you.

It should be the same brand bc I believe that would make it code compliant.
In general, I think ICC is a good brand. I have that for my stove and no issues .

No it absolutely does not need to be the same brand

No need to be

No need to Be.

To the OP,
Go with what bholler says, he’s the pro on here.

The easiest connection will be sticking with the same brand stovepipe as the chimney with that company's supplied adapters. However, some chimney supports can be adapted to other brands without a lot of hassle.

Do you know the brand chimney currently installed?

I definitely recommend the double wall black pipe. I installed a 6in Selkirk double wall flue and didn’t want to replace my stove pipe every few years. Getting their double wall stove pipe, which has a lifetime warranty, was the obvious choice. Of course the adapters all were guaranteed to fit, so that was a bonus.
