I got a stove at a yard sale and want to put in in my shop. It's one that you get from Northern Tool for about $200, I paid $40. My question is can I use stove pipe on the outside as a chimney or do I need to use the insulated pipe. My floor is cement and it will be 3 feet from the wall and I'll use one of the wall pass throughs. If I use insulated pipe, I'll have 5 times more wrapped up in pipe than the stove. Thanks
Let me put it this way... it'll be cheaper buying the single wall pipe (outside) ...until... you see all the creosote running down the outside of it, and dripping from any inside joint it can get to... and then have to buy the double wall anyway. We did that exact mistake with our cabin the first winter. We got lucky (if you want to call it that) because the creosote dripped and got on the side of the cabin making quite a mess, but we hadn't put the last layer of boards on yet, so it got on Typar instead. Replaced the pipe with a double wall (bout $800) pipe and no probs since.
I was going to run it through the wall and up the outside, maybe I an run it straight up and through the tin roof. That way I would need less chimney pieces.
I have to agree with Stinny on this. I know it's just a shop but that single walled pipe will not let that hot gas get all the way to the top without lining the pipe with creosote, especially if you just bought a used stove, most likely not EPA approved. Next problem would be insurance should anything bad happen in the shop. I understand the class A is mucho expensive but so is the shop to any owner like me.

Another less expensive alternative may be running the pipe as much inside your shop as you can and insulating the pipe to keep it as warm as possible until it goes outside. I'm sure there are issues with this as well but it did cross my mind.
That's what I would do, because That's what I did , single wall inside ,ceiling box (my pole barn has a ceiling) and 2 pieces of class A, pipe ,was all I needed for the low pitch roof on the pole barn
Another question. I want to put the stove a little closer to the wall. Right now it is open studs on the inside and sheet rock siding. Is there a type of backer board that I can get for the interior wall, so it can be a little closer? That will help with running the stove pipe straight up and not be so far into the shop.
My shop has no wood framing but I screwed two 4'x8' sheets of Hardieboard into the corner. This is about 7-1/2" from the wall insulation, I plan to add a second steel framed wall with the bottom open from the floor and a 1-2" space between the Hardieboard.
