In many households a focal and vital point of the home is a working chimney which can be used mostly for an open fire that comes with the traditional open fire smell or a stove. However masonry chimney walls are easily affected by the heat and corrosion of combustion products which are produced(e.g soot).

Chimney linings made of clay, ceramic or metal help to provide optimal efficiency for the appliances. Tests in the 1980’s have shown with certainty that using a chimney with no lining increases the chance of a chimney fire,  carbon monoxide leaks and also creosote build-up.

A chimney lining is a conduit that not only provides a passage out for the combustion products but it also proves draft which supplies air to the appliance for optimal combustion. Correctly sized linings are safe and efficient. They provide fluing for modern wood burning stoves and gas or oil furnaces to perform well. Incorrectly sized linings can lead to the production of carbon monoxide with conventional fuels, excessive soot build-up in both the wood-burning stoves and lining.

Chimney linings react differently to being subjected to continual high temperatures with occasional bursts of very high heat therefore proper research should be done before any installation is done e.g which size appliance is needed, how it will be used and also whether the appliance is wood burning only or multi fuel. The suitable stainless steel chimney liner which come with varying warranty periods depending on manufacturer can then be recommended.

Types of Chimney Liner

When it comes to chimney liners, Yorkshire Stoves offers customers a few alternatives that include the following.

Flexible chimney liner

Flexible Metal Flue Liner

This is a twin-walled flexible liner that is suitable for use in lining masonry chimneys providing ventilation for standard fuel oil or gas heating appliances. It can also be used for fires that burn fuels such a coal, coke, wood logs, and dried peat. There are two grades of metal flue liner available, which comprise:

  • 316 Grade Flue Liner – This is made of 316 grade stainless steel complying with BS1449. It is available in 125, 150, 175, and 200mm diameters, with the material designed to withstand normal operating temperatures up to 750°c and short bursts of up to 1000°c. It is supplied and installed with a 10 year guarantee.
  • 904 Grade Flue Liner – This is essentially a higher grade of stainless steel that is thicker than 316 Grade and is supplied and installed with a 20 year guarantee.

Our liners are HETAS approved for use and are in accordance with BSRIA Type Test Cert. No. 14406/1. BS EN1856-2: 2004. They also comply with the European Quality Standard ISO 9002.


Chimney LiningEldfast Ceramic Liner

Eldfast ceramic material comprises two separate ingredients, with these being a refractory ceramic aggregate powder and resin bonding material. When combined they produce a slurry that becomes adhesive if applied under pressure. It is less susceptible to acid attack and general deterioration than more traditional materials used to re-parge flues such as cement and lime/clay mortar, and this makes it a better choice.




puimice chimneyPumice Liner

Pumice is a naturally occurring volcanic stone that can be a good choice of liner for a number of reasons. Its high insulation properties stop heat from being transmitted outside a chimney. This can help to maintain the flue gases at the temperature needed to stop them falling below the dew point, with pumice more capable of doing this than other materials. While it can be used in the repair of older chimneys, pumice is more commonly used for new-builds and is a suitable liner for all types of fuel.
