How long will my stove fit flexible liner last?

I get asked this all the time. The truth is they are to some extent a temporary fix and cannot be seen as a permanent. If you maintain it and use the stove correctly with the right fuel they should give you a life of at least 10 years. 316 twin wall stainless steel liners are the most commonly used and a typical warranty for these is 10 years. 904 grade twin wall stainless steel is a better quality liner and has a typical warranty is 25 years. They all come with a manufacturers warranty but if you read it you will see it is almost impossible to maintain that warranty. For goodness sake get a good make of liner though! If you have a water heating stove then always fit a 904 grade of liner because it is just a much more difficult situation for the liner. Never forget that you a dealing with some highly corrosive products of combustion. Get them swept regularly not only is it safer for you it will also prolong the life of the liner. For myself I am not in favour of burning overnight, it just makes it much more difficult for the liner and causes other issues. When the chimney is swept ask the sweep if tar is present in the liner he should be able to tell you and if it is, what steps to take to avoid it after all that tar corrodes the liner! Try to operate the stove at the correct temperature as turning it down just leads to liner early liner failure.
