I appreciate the info. Just learned something interesting today as I visited a Woodstove store. The new Defiant comes std with a pipe that goes from an oval to a 6" round. Infact, every woodstove in the store(VC, Hearthstone and Lopi) only had a 6" flue option. The wife really liked the Hearthstone Manchester they had there and took me back by even liking the Green Mountain 60.
With the larger stoves like the encore and defiant. The customer had the option of using it like a fireplace or wood stove. To use it as as a fireplace you had to have the 8 inch flue.
I have the 8 inch installed because Im on the shorter end of the minimum recommend height. I wanted to make sure I had plenty of draft as this is how the stove runs best
The option for you to go back down to a 6 inch should be available for your stove.
Your wood is on the wet side so no matter what stove your running your still going to make creosote
For reference lets say my wood is at 18% and your burning wood thats 26% moisture. That is only a different of 8%. So for every 100 lbs of wood you burn you will put roughly 1 gallon of actual water vaper up your stovepipe more then me. Over the course of 1 cord thats thats an additional 30 gallons roughly.. per cord. If you burn 3 cords you looking at 90 gallons of additional water, bro.. thats a ton of moisture..
Use wood like that, and pretty much any stove installed will make alot of creosote
Wood doesn't season in log length or in rounds. If your processing your own wood, you should split and stack it right away. Woodsheds are great split, stack it in there and no babysitting no tarps. The wood dries quick rain never touches it once its in there.
Me personally Id get my wood situation together, put in a 6 Inch pipe and service the stove and put in a new catalyst. Im saying this should be your first course of action because no matter what, your wood supply needs to get better,. You will need to reduce to a 6inch stovepipe if you make the switch to another stove, so really all your out is some basic service on your existing stove, if this doesn't work out.
By doing the above you may not need to spend good money on a new stove and keep the 12 hour burn times that you currently have.
