FAQ
What diameter liner do I need?
For wood burning stoves that have a 5" or 6" outlet, the minimum diameter of flue liner required would be 6", unless the stove has a 5" outlet and is DEFRA approved when a 5" liner can be installed.
How do I measure my chimney, so I know how many metres I need to purchase?
To do this we would recommend getting your chimney swept by a professional chimney sweep and explaining to the sweep that you need to know how tall your chimney is before they start the sweep, They can do this by counting the number of rods they use to carry out the sweep. It is recommended that your chimney is swept before any installation begins, so having the sweep do both will cut out the guess work and could save you ££££!!!
If you purchase a flue liner and on installation you find it is too short you would be forced to buy a new liner at the correct length as you cannot “join” liners together.
Do you offer a fitting service?
Unfortunately we only supply the materials, however you can find a HETAS registered fitter in your local area at www.hetas.co.uk.
Is it possible to install the flue liner / twin wall system myself?
It is possible for you to carry out the install yourself, however you must abide to UK building Regulations, Document J and have a building control officer inspect / sign off the work.
We would recommend getting in contact with building control before you carry out any works, to make sure you are compliant.
