Attic insulation for stove pipe

[Keydiver1]

I’m just getting back on this forum after 10 years.

Long story but back in my house in the Tahoe area. If you search for my previous posts. Take the 1 off my user name. Yes my Waterford is still running well!

I was looking at some other posts and I’m wondering if I should add some rock wool insulation to the 3 - 4 feet of pipe in the attic. The pipe extends 4 feet above the roof line.

Just wondering if this would cut down on creosote build up.

Thanks

Welcome back. No insulation can be wrapped around class A pipe. The creosote problem likely has another cause. The first suspect is wood that is not fully seasoned. The second is that the stove is either not running right or there is air leakage cooling down the flue gases or the fire is smoldering. Do you have a flue thermometer on the stovepipe? If so, what is a typical operating temp?

If you could post some pictures of the stove and the connector we may be able to spot something else.

Thanks for the reply.

The pine is dry as it gets. Got remarried 5 years ago and got access to dry oak that’s been cut down and drying for a few years. Her friends down the west slope of the Sierras.

I’m burning it correctly. Was just hoping if adding a insulation layer would help.

We will convert to a gas stove before we sell and move in a few years.

Normally a modern stove that is running well on a properly sized flue system doesn't get much soot or creosote buildup in it unless it's a cat stove burning low and slow with a cool flue or one with a long, cold, exterior flue system.

Maybe too much single wall pulling out heat?

That's why I asked for some pictures.

It’s single wall to the 8 foot ceiling. Double wall pipe through the attic to the roof.

It’s not a big deal was just looking for options.

Thank y’all

That's a short run. I'm surprised that you are getting creosote buildup.

Dry pine but still creosote from sap.

Still 8 to 10 feet double wall pipe through attic and roof

Plus extremely cold temps.

It’s managemeable. Not a big deal.

I need to sweep once mid winter

Again. Thanks!

Classic Waterford Ashling! Still running strong!

Well burned (in a modern stove) and truly dry pine should not be giving more creosote than other wood.

Regarding the oak, how do you know that it's dry?

 

[Keydiver1]

Moisture meter and they only take down dead standing trees.

 

[stoveliker]

Moisture meter how? On a freshly re-split surface of a piece that is at room temperature?
Standing dead oak does not mean it's dry - and in fact, can be very wet.
