I'm currently running my old Resolute with single wall pipe with no issues. The setup is a straight up run thru the roof with about 6' inside and about 9' Triple wall SS duravent outside. I'm getting ready to install a new Quadrafire Isle Royale so my question is should I switch to double wall inside or stick with the single wall inside. Like I said before, I currently have no clearance issues inside or any real problems with the current setup. My thoughts are that by switching to double wall inside it will help the draft and keep higher flue temps throughout the chimney keeping less possibility for creosote build up. The stove is plenty big for my house so any loss of heat in the room from switching to double wall from single wall should not be noticeable. What do you guys think, worth it to go to double wall or just stick to my single wall setup? Are there any advantages one way or another besides clearance issues?
