A flue is a pipe or duct that safely channels smoke, gases, and fumes from your stove or fireplace to the outsides. It helps maintain air quality indoors and prevents harmful gases, such as carbon monoxide, from lingering in your home.

Flue pipes come in various types to suit different installations, including straight pipes, elbows, T-sections, and adaptors. You can also choose between single-wall pipes for indoor use and twin-wall pipes, which are insulated for added safety and efficiency in exposed or external areas.

The size of the flue pipe depends on your stove’s outlet diameter. It’s important to match the pipe size to the stove’s requirements to maximise performance. Most stove manufacturers will specify the recommended flue diameter in the product manual or specifications.

A flue liner is required if your chimney is damaged, oversized, or not compatible with your stove. Liners improve draft efficiency, protect your chimney structure from heat and corrosion, and ensure safe ventilation. If you're not sure whether your chimney needs a flue liner, speak witha professional to see if a flue liner is needed.

While flue pipes can be installed by experienced DIYers, professional installation is recommended to guarantee compliance with safety regulations and optimal stove performance. A certified installer can assess your setup and make sure of proper connections and ventilation.
