Flues

GR8fires supply an extensive range of high-quality flue components designed to ensure efficient and safe operation for your stove. These include single wall flues, flexible flue liner, twin wall flues and pipe connecters.
We understand the importance of a well-designed flue system, and its role in maximising the performance of your stove.
Our flues are manufactured using premium materials such as 904 grade steel and are built to withstand extreme temperatures and resist corrosion. They are even suitable for use with high temperature gases emitted from multi-fuel stoves.
We also offer a variety of flue accessories, from cowls and tees to adjustable bends and fire stop kits.
Parts are available in various diameters and lengths, allowing you to find the perfect fit for your heating system.
