TheFan....when you guys up in Maine burn 2 to 1 softwood/hardwood, how does that work with creosote build-up...? Does the 1/3 hardwood make the fire hot enough to burn up the creosote..? I've been heating my home here on eastern long island with wood for over 25 yrs.I've never had to use softwoods, we have abundent red and white oak, locust. Just wondering....I clean my flue pipe once a yr.Do you need to clean more often with 2/3 softwood...? I love wood heat...!
