First of all, please excuse any faux pas in my postings - I've never used a forum before. We got our Econoburn installed partway through our west coast winter, and have been burning mostly dougals fir, at least 2 years old. Since Day One, there has been a LOT of creosote, to the point where when the door is opened, ribbons and gobs of it stretch themselves out along the gap. Walls and ceiling of firebox also coated. The longest burn we've got is about 4 1/2 hours. Questions: Would adding storage/buffer make for a much more efficient burn? How do I get the existing creosote off as I clean up for summer non-use? (When it's hot, I can scrape the areas that are reachable, but when cold, it practically needs a chisel. Thanks! When I figure out how to post a picture, I will.
