Flue Systems

Getting the correct flue system for your stove is essential to ensure it works safely and efficiently.


Flue liner & Fittings:

Our flexible liners are made from 316L grade stainless steel and have a 10 year manufacturers warranty. This product has a double skin which is for relining within a masonry chimney and is suitable for use with solid fuel appliances, burning gas, oil, coal, coke, cured dry logs, cured dry peat. In this range you will find all you need from flue liner, adaptors and bends to register plates, fire cement, silicone and chimney cowls.

Twin Wall Black & Stainless Steel Flue Systems:

Twin wall flue fittings allow you to install a stove in a room where there is no chimney. Twin wall fittings clip together and can travel either internally within a building or through an outside wall. Having said this twin wall must be kept at least 60mm away from combustable materials, it is also worth noting that you should not have more than four bends. Our black twin wall fittings have an outer skin which is made from 304 grade stainless steel and is 0.4mm thick. This is then powder coated in a high temperature black finish. The Inner skin is made from 316 grade stainless steel and is 0.4mm thick. Insulation is compressed rockwool giving a density of 128kg per cubic metre. All parts are fully welded. The stainless steel twin wall is also constructed from 316 grade stainless steel and is 0.4mm thick.

Vitreous Enamel Flue Systems:

Vitreous stove pipe and fittings are a single skin flue system manufactured in zero carbon steel with vitreous enamel coating in a matt black finish, which is suitable for gas, oil and solid fuel appliances with temperatures up to 750 degrees C. This type of flue system is designed for internal use in a run of up to 1.8 metres from appliance to chimney and can be connected to a flue liner or twin wall.


Many people fit their own wood burning stoves and some employ a registered “HETAS” installer. Others self install using Building Control (a department in your local Council). Some also choose to do it themselves without involving any authority at all.
