I'll be putting a wood stove in my shop in the next couple of weeks, and I'm not sure what the best way to run the pipe is. It will be near a wall, so going out the wall is no problem. But there is nothing between it and the ceiling, so going straight up seems easy too. I've got a metal roof, and I'm a little leery of cutting a hole in it and having to seal around all the ribs. Any thoughts or advice?
 
Agree w others. Up to near ceiling then out wall. That way heat from the pipe is still inside plus no hole in roof.
 
My next door neighbor did his straight up. Our roofs are a very low pitch 4/12 or 5/12 so the angle was not bad, but it was still a chore for him to get the hole cut right. His runs out the roof and sticks up a good three feet above, but we still get a LOT of smoke in our yard as result. Most days it smells good, but some days it's plain awful. I guess it depends on what wood he is burning.

I'd bet you will still get a good build up of heat at the bend if you make it go out the wall. I'd love to do the same with mine to cut down on my heating bills what with an electric heat pump that is barely keeping the house warm now. Never would have expected the duration of cold we are seeing, though...
 
What they said. Heat is mostly going out the pipe, so keep as much of it inside as you can.... :D :lol: There's an innuendo in there somewhere hahaha.


The top of the pipe should be 2-3 feet above the nearest part of the roof in a 6 foot radius. That way it will keep a decent draft and not want to smoke up your shop when the turbulence blows across the roof and wants to go back down the pipe.
 
wall and use a thimble
 
Keep as much of the pipe in the room as possible to encourage heat transfer from the stove. And the rule is 2ft above anything within 10ft in order to ensure a good draft.
 
Use double wall pipe and I like using dura rock instead of the plywood that normally covers the wall
 
I like consensus! Sounds like the wall is a winner.

Now for more questions:

What is a thimble and where do I get it? My mom collects thimbles, but I assume they are a different type.

Where does one buy double wall pipe? I assume the durarock is just for the wall area behind the stove to keep the heat off and provide some level of fire protection?
 
on my phone search wall thimble.
prevents combustible material from combusting due to contact with exhaust pipe and doesnt requie a bigger hole.
 
Thimbles an insulated pipe sometimes w flanges, to stick through the wall and the stovepipe runs through it to stop a wood wall from catching fire. I've seen it done homade w coffee cans and sheet metal and insulated w fireproof insulation.If you have a metal or block wall you might not need a thimble. I would use single wall pipe, you'll get more heat in the building and a fan pointed at the stove or ceiling fan will spread the heat around.
 
Through the roof is much cheaper, especially if you have a vaulted ceiling.

Mine is in my house but I used a double wall, adjustable inside going to the stainless INSULATED double wall through the ceiling using the ceiling kit and the super pro pipe from lowes. The double wall stove pipe inside cuts your clearance to combustibles from 18 inches to 8 (or 6).
 
I went out the wall in my shop as well. something about poking that hole in the roof just didn't make me feel warm and fuzzy. I would not worry about The insulated pipe in a shop. Waste of a lot of money in my opinion.
 
As much pipe inside...and straight up thru the roof. If I can install all that myself in my house 12 yrs ago and still not have any leaks.....anyone can!
