Replacing Fire Bricks 

Firebricks are consumable goods which do require replacing after a period of time, the lifespan of firebricks can vary due to numerous different factors such as:

• Thermal stress: Rapid changes in temperature can cause bricks to expand/ contract too quickly, causing cracks. 
• Moisture: Using fuel with a high moisture content can cause bricks to wear quicker 
• Over firing: when the temperature inside the appliance rises to a level that the bricks cannot handle, causing them to crack. 
• Age: Over time, bricks will become worn and will require replacing. 
• Impact damage: Dropping heavy fuel onto the bricks or hitting the bricks with a tool can cause them to crack.
