This is only true if you ignore labor costs. The disparity of cost is even greater for an inside chimney on the first or upper floor.

This is, more often than not, the practical realism that is necessary when this topic pops up from time to time. It's inarguable that masonry is the longest lived chimney. Keep it dry and a good quality SS should do you well.

Mine is the exact situation that franco b states, middle of the house on the first floor directly above a garage bay. My SS is entering, I don't know for sure, but it's at least its 13th and likely 14th unscathed season. Masonry would be wonderful if I installed a 30' long vertically laminated beam directly below the chimney block, not to mention that my wife** would have to accept looking at an obelisk in the room which would also push the stove out further out from the wall, eating up more floor space. I admit, I've installed the beam but there's not gonna be a coal heated doghouse** in my future :roll:

Jack, I know what you mean, I've seen them fail with OIL use - no coal. I personally replaced a stainless stack on a home (not mine) with masonry, it was 316ti 8" that rotted and failed badly with an OIL boiler after 10-15 yrs. There has been multiple posts on this site about documented complete failures of even the best 316ti stainless with coal after as little as 3 years. Those that get more than a decade are the exception, NOT the rule.

I was even going to throw up a masonry stack for a member in upstate NY, but he still went with 8" stainless. I've seen them fail badly with coal and forum members have posted many pics of instances of failure, but people still want stainless. Interior stacks are no big deal either, I'm not sure there is this fear or aprehension about putting a stack through the house, in some cases it might be a bit more $$ to trim it off/finish the block nicely, but still pretty simple and straightforward.
