This complete fire brick set replaces all bricks in the Warrior Aiden firebox, including the rear and both side positions. The Aiden is a large stove sold in boiler and non-boiler versions across the UK and Ireland from around 2006 to 2018. Replacing the full set at once ensures uniform fit and consistent thermal performance. ✅ Compatible with: Warrior Aiden (boiler and non-boiler versions) 🔧 Specifications Material: Vermiculite Heat resistance: 1200°C Part type: Complete fire brick set Fire bricks only need replacing when they crack to the point of exposing the stove's steel bodywork to direct flame contact. Replacing a full set in one go prevents mismatched brick heights and gaps between bricks, both of which reduce heat retention and combustion efficiency.
