"So there are different grades of liners. So long as ur burning the correct fuels ur liner should last. But frequency moisture incorrect burning can alter all of these. 904 liners ur best ones"

"Clay tile liners and cast-in-place liners typically last around fifty years.
Stainless steel flue liners generally last for fifteen to twenty years
(though low quality liners may not even last for five)."

"How long they last depends on how well they're looked after(swept regularly) and if the correct fuel has been burned.
A lot of liner manufacturers will offer lifetime guarantees on their liners(providing the above has been done).
In reality though, it is the lifetime of the stove. Because any time you change the appliance, you should really re-line the flue. Particularly if you didn't install the original liner."
