Hi, im new to this forum.

I just purchased a drolet heatmax furnace to replace the scary homemade wood furnace in the basement of the home we just purchased. The house is a one story rambler with a full basement. The existing chimney is an 8 inch exterior masonry chimey with a thick metal liner. The chimney is approx 20 ft tall. My plan is to line the existing chimney with a 6 inch insulated stainless steel flex liner. I know that interior chimneys perform better, but I really dont want to install a new chimney. According to the previous owner, he had no draft issues with the existing uninsulated chimney. Do you folks think my planned set up will work safely and perform adequately?

Any info or comments would be appreciated.
 
I was going to say the same thing but I didn't want you guys thinking I was a sinner
 
6 inch liner would be the best way to go. Do it right the 1st time.
 
8" although not ideal, maybe fine. The problem though, could be the construction of the chimney. Around here, people use old well casings, or whatever they get their hands on. For piece of mind, I would hire a sweep to clean and inspect the chimney. If you just purchased the home, was there any notes on the chimney from the home inspection?

Yeah, but I never seen a well casing inside a masonry chimney before...kinda sounds like that's what he has though?
