I have had 2 chimney fires in terracotta/cement/brick chimneys without harm to them.
Now I understand the HeatsTwice better
The problem is that most folks have no idea about if or where the contractor that built the house and the mason that built the chimney might have fudged a bit on clearances. Then when one really needs the chimney to be in great shape and has a hot fire burning 24/7 - boom, pyrolysis hits. It's a crapshoot, but each chimney fire has the potential to compromise the system a bit more. They are really best to be avoided in the first place.
It wouldn't surprise me if that is what you understand given your propensity to used innuendo to muddle clarity on many issues I have seen you comment on.
But that aside, I can say that you are correct about how contractors fudge on building codes. I personally have had a sub floor fire caused by improperly build firebox which mated right up to the wood with only a brick vinere between them. Cracks in the mortar allowed plasma to reach the wood subfloor and ignite a smolder – which caught fire as soon as the fire department cut a whole in the family room floor using a chain saw.
BTW, has anybody ever noticed that the fire department often does more damage to a structure than what the fire could have done? I watch these guys drag an ax right into a 4x6 glass door, laugh, and tell me that the insurance company would take care of it.
