Need help choosing?Why Replace Your Old Ceramic Coals?
Ceramic fire-bed components can deteriorate through prolonged use. Customers often replace them because they are worn, damaged, faded or no longer giving the desired appearance.
-
Restore the appearance
Fresh black ceramic coals restore a cleaner, more realistic fuel-bed appearance.
-
Realistic flame effect
Irregular Random shapes help create a natural coal-bed appearance when arranged in accordance with the appliance instructions.
-
High-temperature ceramic fibre
High-temperature ceramic fibre designed for use in living-flame gas fires, with excellent heat refraction and radiation.
-
No ash or real coal mess
Enjoy the visual effect of a traditional coal bed without handling real coal or ash.
Designed to Refract & Radiate Heat
High-temperature ceramic fibre helps refract and radiate heat from the fire into the surrounding area, contributing to the characteristic warmth and glow of a traditional gas coal fire.
Replace worn or damaged ceramic coals with suitable replacements in accordance with the fire manufacturer's instructions, to help maintain the intended appearance and performance of your fire.
