Trying to decide on what new stove to get

I would talk with the folks at Englander about the 8 inch chimney, and do what they say. Logic says "bigger is better, so 8 inches is better than 6," but that is not correct when chimney sizing. They have to be "rightsized."

Oh man, that is a REALLY BAD question to ask around here!! They will have you in bankruptcy court in no time! You'll need at least 2 new sheds just to house all the new tools you'll be buying!!

Good luck with the new stove!!!!

 

How tall is your chimney? Unless it is really tall, 8" probably isn't gonna cut it.
To answer your question though, the further you can go 6" the better.
I have a stove that is meant for a 6" chimney running on a 8" chimney, it is not ideal for sure. Crappy draft unless is is pretty cold out, smokes out the door on reloads, low BTU output once the secondary burn is done. I am fully aware this is all from too big chimney. My plan is to drop a un-insulated 6" liner inside the insulated 8" liner, problem solved. Kind of a "superinsulated liner"
My suggestion is to do it right to begin with, save yourself the frustration of "problems with this new stove". Remember, the chimney is the engine that drives the stove...

 

NC30 is a good choice.
Definitely go 6 inches from the stove to the ceiling, that's how mine is set with my 8 inch chimney, I have a total of a 15 and a half feet straight up, draft is good, I don't have any problem with smoke coming out during reloads or anything .
All the research I did before I installed the current stove said that's the way to go and will give you a better draft, there are people on the other form also that have 8 inch chimneys and all are set up with six inch stove pipe, theirs and mine all work good, if I remember right I think a couple of those people have NC 30's, maybe mike holton will chime in here and give his professional opinion.

Whether you are using single wall or double wall, I suggest you get a telescoping stove pipe for easier install

 

I assume that your chimney is already three feet above the highest point on your roof, is that right?

 

Fwiw your wife will rarely if ever touch anything other than maybe the tstat on a king unless you are gone for days at a time.

 

Pretty sure the chimney is 13' and a few inches off the top of the stove. Been a few years since I installed it but I know its over 13'.

Planned on the telescoping stove pipe.

Chimney cap is right at 3' above ridge and more than 10' away.

S&W - I was all set to get the BK but I'm taking one for the team. I got the GMC, Kubota, equipment trailer, and tons of tools and supplies for the shop this year. Mama gets a vacation and I get a big upgrade in a stove.

 

Just reread my last post. Looks like she's been taking one for the team all along. That's my girl.

 

So, slide 6" stove pipe inside the 8" class A???

 

Not an expert, but it meets clearances and would be insulated by default. Run with it

 

Thinking I want to go with this stove pipe.

I'm guessing the magnetic thermometer won't be accurate anymore with the double wall.

 

Correct

 

If it's 13', I'd lay some pretty good odds against that working as an 8", might be tight as a 6", 15' is usually considered a bare minimum height for modern stoves. But since it sounds like it is a straight up chimney, that helps, 90* bends in chimney pipe are hard on draft.
I hadn't thought of your stove pipe inside of the chimney idea, but that sounds like a simple/easy solution since you have a straight up chimney. Might hafta get a clamp on chimney liner top plate to seal the gap and "hang" the pipe up top...

 

If he uses a 6 inch liner run down through the 8 inch class a it isn't oversized any longer

 

I shoulda read down farther lol
