Why does fireclay deteriorate over time?
Due to its high mineral content, fireclay also has a slight disadvantage:
It is relatively brittle.
Due to prolonged exposure to high heat, it will eventually develop cracks.
These are initial signs of wear and tear on the material, but not yet a reason for replacement.
Fireclay should only be replaced when parts of the material fall out and the protection of the oven can no longer be guaranteed.
Therefore, the fireclay should always be checked during the maintenance of a fireplace.

Two questions repeatedly arise in this context:
Is a broken firebrick after prolonged use covered by the warranty? No.
The combustion chamber lining is treated as a wear part.
Does the stove manufacturer, the chimney sweep, or the dealer have to replace the fireclay?
The same applies here. A clear no.:
The operator of the oven is responsible for the lining of the firebox.
While you could hire a professional to do it, anyone with manual skills can also do the replacement themselves.
Another good news: The replacement material is significantly cheaper than you might think.
What exactly is fireclay?
The term "fireclay" (also "chamotte") is often used synonymously with refractory bricks. When a specialist speaks of fireclay, they are referring to a natural product, a refractory material. It is very heat-resistant and has excellent heat storage properties, making it ideal for fireplace and stove construction.
