I have an easy roof to get onto so i cleaned the cap by hand and the soot eater did a good job with the rest. I didnt have a draft issue so I cant answer that but here are a few things ive gathered from asking similar questions on this site..... how tall is your chimney? Whats the moisture content of a fresh split at room temperature? What are your stove top temperatures? What does your stove do if you throw wood you know to be dry into it. The draft issue you think you have might just be something else. For me it was mediocre wood. If i toss pallet wood in my stove it looks like the gates of hell.Thanks. I think I may have a similar isse at the top of the chimney. It seem like I have a hard time getting a good draft, I know I burned too cool for a while as well. I'm going to clean it this weekend. How clean dis you get the top of yours? Did that seem to help?
