Twin wall flues are insulated chimney systems for open or closed solid fuel stoves, condensing and oil fired appliances. They can withstand continuous operating temperatures of up to 450°C and are perfect for wood burning stoves, gas coal effect fires and oil boilers. Great for new build and renovation projects as they are a simple and cost effective solution for those without a brick chimney stack or an existing chimney stack, so you can install a stove in any room.

Twin Wall Chimney Flue Essential Info
Nationwide Chimney Components supplies premium high quality twin wall flue systems and twin wall flue pipes, including stove pipes, to meet your heating requirements. Our twin-walled flue products have adjustable-length pipes for indoor and outdoor flues and biomass boiler installations.
They have a simple twist-lock bayonet jointing system and are available in high-grade stainless steel or black twin-wall flue pipe in all sizes. HETAS approved so they meet building regulations. We also supply all the flue installation materials compatible with multi-fuel stoves to make installation easy and compliant.
The external diameter of double-walled flues is 60 mm more than the inside diameter. So, a 150 mm pipe has an outer diameter of 210 mm. Our twin wall flues can pass through floors, roofs, or walls, depending on your required flue route.
We stock the Schiedel flue system and are one of the UK’s leading providers of flue supplies including chimney cowls and flexible flue liner.
We also offer a comprehensive range of flue installation materials, such as wall support, wall storm collar, locking bands, roof support, or a simple starter length, which ensure compatibility with multi-fuel stoves and ease of installation for both existing chimneys and new constructions without an existing chimney stack.
What is a Twin Wall Flue System? +
A twin wall flue system is a clever chimney system that safely and efficiently vents flue gases from wood burning stoves and condensing boilers. It has two concentric walls with insulation sandwiched in between. The inner wall is usually stainless steel or vitreous enamel and is designed to be durable and heat resistant. The outer wall is usually stainless steel or aluminum and adds extra protection and strength. The insulation in between the walls is what minimises heat loss and makes the system more efficient. Twin wall flue systems are designed to be a reliable venting solution for flue gases so are perfect for all types of heating appliances.
Benefits of Twin Wall Flue Systems +
Twin wall flue systems have many benefits over traditional chimney systems. One of the biggest is their flexibility and ease of installation. These can be installed through walls, floors and roofs, so they are perfect for existing buildings where a traditional chimney stack may not be possible. Twin wall flue systems are also more efficient and safer, reducing heat loss and flue gas leaks. They’re also aesthetically versatile and can be finished in various colours and finishes to match the surrounding architecture. All this functionality and style makes twin wall flue systems the perfect choice for modern heating.
Twin Wall Flue System Installation +
When installing a twin-wall insulated flue system for your appliance, it is essential to contact a HETAS-approved tradesperson to ensure that the twin wall chimney flue is fitted correctly and meets building regulations.
