Twin Wall Flue
Twin wall flues are specialised insulated chimney systems designed for use with open or closed solid fuel stoves, including condensing and oil fired appliances. They can withstand continuous operating temperatures of up to 450°C and are perfect for heating appliances such as wood-burning stoves, gas coal effect fires, and oil boilers. These flues are ideal for new build projects and renovations as they are a simple, cost-effective solution for those without a brick chimney stack or an existing chimney stack, allowing for the installation of a stove in almost any room. Take a look at our article on fitting a twin wall system. We offer a wide range of chimney flue supplies, including chimney cowls, chimney liner, and flexible flue liner, to ensure your system is complete.
Nationwide Chimney Components only supplies premium, high-quality twin wall flue systems and twin wall flue pipes, including stove pipe, to meet your heating needs. Our twin-walled flue products include pipes with adjustable lengths, making them suitable for indoor and outdoor flues and biomass boiler installations. These products have a simple twist-lock bayonet jointing system and are available in high-grade stainless steel finish or black twin wall flue pipe in all sizes. They are also HETAS-approved, ensuring that they meet building regulations. Additionally, we provide all necessary flue installation materials, compatible with multi fuel stoves, to facilitate a smooth and compliant installation process.
