Hi all, I had installed a new hearthstone stove last year. I had a 90 degree elbow in my setup which I believe was contributing to my semi-poor draft. I plan to ammend that to two 45's this year. I figure it can't hurt to try it out. The thing I'm grappling with is, should I stay with the single wall pipe, or upgrade to the double wall? There's several pros and cons here which I'm sure some of you have already debated. Pros of single wall 1. Since I have a soapstone stove and do start it from cold on almost a daily basis, I do get my initial heat from the stove pipe while the soapstone is coming up to temp. 2. I'm also a compulsive stack temp watcher which is very easy to monitor with single wall. I understand is much less accurate with double wall. 3. It's already there. Double wall is big $$$. Pros of double wall It's much safer in the event of a creosote flare up. While double wall can handle up to 2100 degrees, I could kiss my house goodbye if my single wall went up. This one alone could be the reason to do it. Any advice on which way to go?
