Installing a wood stove
If you have an existing chimney installing a wood stove is relatively easy. The fitter will usually insert a liner inside the existing chimney from the burner to the exit point. For straight chimneys this can made up of sections of jointed metal pipe, which can be either single or double skinned. A double skin is more airtight and lasts longer than a single skin but of course costs more.
For chimneys that aren’t perfectly straight, a flexible non-flammable liner is used. It is important to note, chimneys should be swept at least once a year and twice if they are in heavy use. Otherwise, creosote (a by-product of inefficient combustion) builds up on the walls of the chimney to become a fire hazard. Creosote builds up gradually over time as fires burn less efficiently when they are just getting started, but can accumulate very rapidly if you burn unseasoned or damp wood. Read more
