just be careful on old houses...having grown up in one with a 250 year old chimney.
Old stone mortar may have fallen out and a superhot planned or not chimney fire can go through cracks and potentially cause a fire.
I went out on at least six fire calls on chimney fires that had put smoke in the attics or even caught something on fire.
so the statement about chimneys in good condition is super important.
Burning creosote reaches temps much higher than normal fire temps so it puts quite a stress on the system.
All the more reason to not let it get on fire by keeping the worst of it cleaned out.
Lot has to do with what kind of wood is burned. I think I remember RS saying something about burning pretty green wood last year, and
no surprise he has very heavy creosote buildups.
Didn't they use to pull christmas trees up the chimney to clean them? What a mess that would make...
though maybe they just use artificial trees now. This of course would not work with a modern smaller round flue but some of the old stuff was much bigger.
I'm happy to pay a hundred bucks every two years and have them come out and do mine with their HEPA vac running. I had all three cleaned when I bought the home, but only really use one, in the den, so that's all I'll get cleaned next year. I looked up the flu with a bright light and it had just a very light coating. Fine for this year. I used a really bright flashlight and looked up as far as I could see, and got pretty dirty in the process, but wanted to make sure no critters had gotten through the chimney screen on top and made a home in there before I lit it up. Clean as a whistle, though why would a whistle be particularly clean?
