Why Use Liner?
At Wolverhampton Fireplaces and Stoves we strongly advise all our clients to have their chimney lined prior to the appliance being installed by a competent HETAS-approved person, or indeed one of our own engineers can carry this out whilst fitting your stove.
We sell 2 types of liner Systems here, 316 Grade that carries a 20 Year Warranty or 904 Grade which carries a 35 Year Warranty and all produced locally in the Black Country.
The benefits of lining the chimney are extensive, and we believe the following advice from Clearview Stoves best sums up why we believe you should line your chimney:
“A chimney is a passage from the place of combustion to the outside world. Warm flue gases should rise through this passage to the point of exit. For a chimney to operate satisfactorily it should be smooth, warm and as straight as possible. If a chimney is irregular and rough, or cold and damp, flue gases will move slowly. Cooler gases will mean inadequate chimney suction and poor flue gas speed.
We always advocate flue lining where possible for the following reasons:
- A flue liner will substantially decrease your chimney volume. Consequently, higher temperatures will be maintained and flue gases will travel faster, generating a greater and more consistent draft. When possible, flue liners should be insulated, increasing flue temperature. A warm flue will collect less deposit, cleaning will be much easier and condensation should not occur in the flue. It is possible to clean a lined flue well, leaving the liner almost as clean as new. It is rarely possible to remove all deposits that accumulate in unlined flues as there are always holes and corners a brush does not reach.
- The combination of a Clearview clean burning stove and a warm flue liner should mean chimney fires are a thing of the past. Chimney fires are a common and frightening occurrence in an unlined chimney and may cause substantial damage.
- A well installed stove should emit no smoke or fumes to the room. If a flue is damp and cold it will produce a poor draft, this poor draft may reduce further during slow burn periods as the flue cools. Chimneys are usually in much better condition externally than internally. Many years of sulphur attack may have eaten half way through brickwork and mortar. Internal feathers dividing one flue from another may have perforated or collapsed allowing flue gas to pass into redundant, uncleaned flues.
Clearview Stoves produce little smoke; some five times less than conventional stoves. They are tolerant and less demanding than other stoves and will operate in most unlined chimneys, however we advocate lining to avoid risks and long-term problems. When using a stove to heat radiators we would advise a well insulated flue liner is used without exception.”
