When we survey your property this will include an assessment of the type, size, age and condition of your existing chimney. Usually, older brick built chimneys do need to be relined with a flexible stainless steel flue liner. Chimneys were built for use with open fires, which heat the chimney, thus allowing it to draw correctly. Because stoves are much more efficient than open fires and the gases produced are much cooler, the size of the flue needs to be reduced so that the chimney draws.
If this isn’t done, a lazy flue can result in all sorts of problems including making the stove difficult to light, causing smoke to spill back into the room when lighting and refueling, and creating a lining of tar inside the chimney which can in turn be ignited and cause a house fire.
If you have a newer existing chimney which is sound (for example it has a clay liner system installed) it may be possible to install a stove without relining the chimney. This is subject to an inspection and test on your flue, which we can carry out for you.
