flue sizing for woodstove

Hey everyone

here's what I've got going on...

I'm building a wood stove for our tiny house project (I'm a welder/millwright). the sizes of the stove are going to be custom at 12"Wx12"Hx14"L. I'm having difficulty in finding out what size vent and intake I'm going to need to put on it.

I'm probably going to use a double insulated chimney straight run with a 12' rise to clear the crest of the roof.

Any thoughts?

Thanks in advance

Navigator stove works makes a stove about the same exact size as the one your making, and it uses 4" piping and they are very efficient good burning stoves.. However 4" insulated pipe for wood stove usually has to be ordered.

Go to www.marinestove.com there is all kinds of info in the manual section as well as the forum there..

Hi Darren,
Cool project!

Maybe you could use 6" (the most popular) I would ask Andrew at NSW first.

Just as in the above post I would look for stoves of comparable size and see what they use. Before you get started though know that insurance people are dumb when it comes to wood stoves and it could be a problem getting insurance with a home built.
I can get all the wood I want for free but the cost of insurance makes it more than the natural gas we use now.

With a straight run (no elbows) you want to think about a spark arrestor plate under the outlet.
If comparable stoves have a 4" pipe I would make yours 5". Use a run of 5" then reduce to 4". As the gasses cool this will help maintain velocity. Might not be such a problem with double wall pipe - it doesn't shed heat like single wall.

Thanks for the replies..!

this way we get a way from a couple potential issues (esp for insurance and safety reasons).
A) We won't have a flame going straight into my chimney
B) We have 2 different ways of dampening the air flow

Thanks for the info on the navigator. I'll be checking out what they have going on with those stoves.


CHEERS!

Here's the basic design of what I'm building.

Looks like a really good design man! Check em out. NSW makes really beautiful cast iron stoves. Andrew makes each one himself one at a time, so there is a wait.. But he is also helpful with answering questions..

A 6" pipe is probably a easier pass with insurance guys but i don't know if that would draw right..

I'm interested to see what a "pro" would say about your interesting build.. My buddy is interested in making his own stove too. I have a NSW-2 little cod but haven't fired her up yet. I bought her while I was planning my own tiny house build, now I'm buying a small house with land in the town I grew up and close to work.. Still love the stove though and plan on having installed one way or another.

Good luck!
