Why do I need to line my chimney for a wood-burning stove?

John Conlin / 21 February 2018

A reader is intending to fit a wood-burning stove, but has been told to line his chimney. Chartered surveyor John Conlin explains why.


I intend to fit a wood-burning stove in the fireplace of our sitting room, but friends tell me that I will need to line the chimney. Why can’t I just put the short pipe that came with the stove up the chimney?


Your friends are correct. The combustion fumes from enclosed stoves are much hotter than those from an open fire and will damage an old chimney.

Also, the flue needs to be sealed from stove to chimney pot to prevent toxic contamination of air within the living space.
