Chimneys can need lining for several reasons:
- If the flue is leaking smoke from your appliance into another room of your house
- If the flue that is already installed is too big for the appliance being used
- If the flue is external and too cold to draw air in properly
- If tars and condensates are coming through the chimney in any part of the building and causing staining
There are many different ways of lining a chimney, the suitability of these methods depends on your individual system. Always seek the advice of a HETAS qualified installer on which solution is the best for you.
