Advice and tips

How often should the chamotte lining or individual chamotte tiles be replaced?

The integrity and condition of the chamotte lining must be monitored during the heating season. The spaces between individual chamotte tiles/bricks prevent the tiles from cracking due to thermal dilatation and must not be filled in any way, e.g. with grout, as was usually done in older solid fuel heating units. Cracked chamotte bricks do not lose their function, unless they fall out completely. If a piece of chamotte lining falls out, it will need to be replaced.

Replace chamotte lining/bricks in accordance with the operating manual provided with your fireplace stove or insert.
