In heating and combustion systems, the correct evacuation of flue gases is an essential factor in ensuring safety, efficiency, and equipment longevity.
Among the most widely used solutions today are flexible stainless steel flue liners, which offer an ideal combination of durability, adaptability, and ease of installation.
What are flexible stainless steel flue liners
Flexible stainless steel flue liners are metallic ducts designed to carry combustion gases and flue gases from appliances such as:
· heat recovery units
· wood-burning stoves
· boilers
· pellet and wood heating systems
Thanks to their flexibility, these liners can adapt to a wide range of installation geometries, making them particularly useful in chimney relining and retrofit projects.
Key advantages
Flexible stainless steel flue liners offer several technical benefits:
High thermal resistance
They can withstand very high temperatures without losing structural integrity.
Durability
Stainless steel provides excellent resistance to corrosion and wear.
Installation flexibility
They can be fitted to existing flue systems and routed through complex pathways.
Safety
When certified, they ensure the safe evacuation of combustion gases.
The importance of European standards
To guarantee safety and quality, these products must comply with rigorous technical standards, such as EN 1856.
These standards set requirements relating to:
· thermal resistance
· fire performance
· material durability
· structural performance
CE marking is a key indicator that a product meets the requirements set out by European legislation.
Most common applications
Flexible stainless steel flue liners are used in a wide range of applications, including:
· relining of existing chimneys
· connecting heating appliances to main flue ducts
· residential building installations
· industrial flue gas extraction systems
