Last Thursday we had a chimney fire. Looks like its time to line the chimney. We operate a 1984 Stadler Wood Boiler with a built in thermostatic control on this flu. Looking at SS liners as well as a poured in Supaflu liner. No experience with either and would like to know the benefits and drawbacks to both types of liners. Does the creosote stick to the poured in the Supaflu liner like my old flu tiles making it nearly impossible to fully clean this style flu? I have been told that the creosote does not adhere to the SS liner and is very easy to clean. One company suggested an oval SS liner due to the fact that our flu was built with a bend around the fireplace. We have a central fireplace/chimney with 4 flues and 2 fireplaces. Approximately 30 foot run. Our question is how easy is the oval SS liner going to be to clean and if there a special brush for the oval pipe? What is the best brand and quality of SS liners? I was told the HomeSaver Brand is the best and that their Pro line is superior to their UltraPro line? Is Supaflu the best brand of poured in liner? Does the poured in liner hold up..cracking, deterioration, etc.? All feedback will be appreciated/thanks.
