Home improvement solution that reduces fuel consumption and increases heat output when lining a wood burner firebox. Fewer trips to tend the fire and steadier warmth for chilly rooms with the Vintage Decor Fireclay Coalsaver Fire Brick Set. Worth the effort to fit to a grate — will the fuel saving and safety benefits justify installation?
⚡ At a Glance
- • Heat Retention: Reflects heat back into the firebox, reducing heat loss and raising local temperatures
- • Best for: Owners of wood burners or open grates who want to conserve fuel and improve safety
- • Not ideal for: Fireplaces with openings outside the 14 to 20 inch range without selecting the correct size
Made from refractory fireclay, sold as a set of three bricks with two reversible side bricks and one back brick. Lining the inside of the firebox reduces grate size and reflects heat back into the firebed, helping fuel burn more efficiently.
More concentrated heat – thanks to fireclay lining that reflects warmth
Refractory fireclay has low thermal conductivity and reflects radiated heat back into the firebox, rather than letting it escape into surrounding masonry. Lining the sides and back alters the heat profile inside the firebed so more energy stays where the fuel burns.
Stronger, more consistent heat from the same fuel load, so rooms warm faster and retain warmth for longer.
Lower fuel consumption – with coalsaver design that reduces grate size
Coalsaver bricks narrow the effective firebed area by forming a smaller internal chamber, which concentrates the fuel and combustion zone. A reduced grate area uses less coal or smaller log volumes while maintaining effective temperatures.
Smaller, hotter firebed means less fuel required per burn while achieving comparable heat output.
Improved containment and safety – with reversible side and back bricks
Side and back firebricks create a physical barrier that prevents coal, logs and other fuels from spilling forward or tipping over the fret. The reversible design allows placement to suit different grate shapes and orientations.
Reduced risk of fuel falling out of the fire opening and a safer burn, which is especially useful if the fire is left unattended.

❓ Frequently Asked Questions
Q: Will these bricks fit my stove or grate?
A: Universal reversible side and back bricks are designed to fit most grates and wood burners, with sizes available to suit fireplace openings from 14 inch to 20 inch; checking the opening size before ordering is advised.
Q: Do the bricks actually reduce fuel use?
A: Lining the inside of the firebox with fireclay reflects heat back into the firebed and reduces the effective grate size, which reduces the amount of coal or wood needed for the same heat output.
Q: Are the bricks safe to use with an unattended fire?
A: The bricks help prevent coal, logs and other fuels from falling out the front of the fire and tipping over the fret, which can be an important safety measure for fires that may be left unattended.
