Why Flexible Flue Liners Are Essential for Chimney Stove Installations

Introduction

When installing a wood-burning stove into an existing chimney, one of the most important components is a flexible flue liner. Without a properly lined chimney, your stove may struggle to draw correctly, resulting in smoke leakage, reduced efficiency, and even dangerous carbon monoxide risks.

What is a Flexible Flue Liner?

A flexible flue liner is a corrugated stainless steel pipe that runs the full length of an existing chimney. It provides a smooth, continuous passage for smoke and gases to exit your home safely.

Benefits of Flue Liners

1. Improved Draft – Creates a consistent, correctly sized passage for smoke.

2. Prevents Leaks – Stops harmful gases escaping through cracks in old brick chimneys.

3. Boosts Efficiency – Ensures the stove burns at optimal performance.

4. Easier Cleaning – Smooth surfaces reduce soot buildup.

5. Compliance with Building Regs – A requirement under UK regulations for most installations.

   
   

When to Use One

• If your chimney is unlined or in poor condition.

• When converting an open fireplace to a wood burner or multi-fuel stove.

• If your existing flue is the wrong diameter for your stove.
