Flue Liner

A flue liner is a flexible stainless steel tube that hangs down from your chimney pot or stack and connects into the stove pipe that slots into the flue collar of your log burner or gas stove. A flue liner, which is often referred to as a chimney liner or steel flue, sits on the inside of your brick-built chimney and carries the exhaust gases away from your stove and up your flue liner instead of releasing them directly into your chimney cavity. In StovesAreUs’ collection, we have a variety of stainless steel flexible flue liners, so shop the full range below.

Chimney Flue Liner

Here you'll find a wide chimney flue liner range with flexible options for your wood burning stove installation process. A good quality flue liner can last up to 25 years if maintained correctly and used with the right type of fuel, so it is well worth investing in the best. Rest assured, we only stock the highest quality flue liner for chimneys here at StovesAreUs.

There are two different grades of flexible flue liner available in this range: 316 grade flue liner and 904 grade flue liner. We recommend 316 for stoves that will be used for burning seasoned wood and for the occasional use of smokeless coal. 904 grade on the other hand is recommended for hard working stoves that burn a mix of seasoned wood and smokeless coal or smokeless coal on its own. Both of the good quality flue liners that we supply are Hetas approved and should last up to 25 years if maintained correctly and you use the right type of fuel.

Frequently Asked Questions

Do I need a flue liner for my chimney?

Although it is not a legal requirement to fit a flue liner with a stove, most stove retailers and HETAS installers recommend that you do. Without a flue liner, it is difficult to determine the quality and performance of the chimney. Issues like poor flue draught, lighting difficulties and shorter burn times are less likely to occur if you opt to fit a flexible liner.

What are the benefits of flue liners?

One of the most significant benefits of flue liners is ensuring a safer chimney. Older chimneys often require a flexible flue liner solution as over time they can lose their structural integrity and/or become worn. The liner can also increase efficiency by insulating the flue gases and keeping them warm as they travel upwards to promote good draught.

What size flue liner do I need?

When buying a log burner, gas stove, or multi-fuel stove from us, you’ll be provided with the diameter of the flue collar within the specifications — this is often a good guide to gauge the size of liner required for the stove. However, the size of the stove collar does not always correspond to the size of the flue liner you’ll need, so ensure you check the manufacturer's instructions before you purchase a flue liner.
When measuring the length of your flue liner, you must ensure it is long enough to reach from the top of your chimney to the bottom of the fireplace opening. We recommend ordering an extra metre or two of flue liner to cater for any bends or offsets that you may have within your chimney space. In this collection, you’ll find 5-inch, 6-inch, 7-inch, and 8-inch stainless steel flue liners.
