What bad habit? I never said I was in the habit of burning unseasoned wood. The point is that it's not, as you said, bad for the environment. Burning wood is mostly carbon neutral. And Stovax reduces the risk of chimney fires, which largely arise out of deposits; it doesn't eliminate them. Although it definitely does make chimbleys easier to clean. Perhaps not important if you're paying the bloke x quid anyway, but useful if you're doing it yerself! ;-)

If it increases the risk of blockages, I can only imagine your's is two inches wide (never mind the quality, feel the width! Phwooooar!!) Further, I would point out that, whilst it may not be true in older properties, CO poisoning should not be a risk. The previous owners (vandals) had ripped out the purpose built Aga, alas. I had the multi-fuel stove installed. The chap doing it used a massive drill bit make a 4" (or possibly more) hole in the exterior wall. Purpose? Air-flow - precisely to prevent CO build-up. Can't answer for older properties or open fires, but it shouldn't be a risk with a properly installed stove.

Did you enjoy the poems, yer miserable bugger? ;-)
