I just had my old brick chimney lined with ceramic. The old clay liner was gone due to the association rules that will not allow modern stainless steel vents that are required for efficiency furnace or heaters. The HVAC tech warned me and the association directors that it will destroy the chimney.

Now that it had happen, the association did an expensive 'cast in' ceramic flue. Suppose to be much better than stainless steel which will break down in a long burn chimney fire and over time corrode. The ceramic flue should last a lifetime but it is subject to cracking should the chimney ever move.

Thought you might want to check that out.
