Flue Draught
The chimney has two main functions:
To safely remove the smoke, gases and fumes from the house.
To provide a sufficient amount of draught in the appliance ensuring the fire keeps burning.
Draught is caused by the rising hot air in the chimney when the appliance is lit.
Symptoms of poor performance related to flue draught include:
Excessive fuel consumption (high flue draught)
Poor burning control, overheating (high flue draught)
Wind noise from air controls (high flue draught)
Difficulty getting a fire going and keeping it burning well(low flue draught)
Low heat output (low flue draught)
Smoke entering room when doors opened (low fluedraught)
The construction, position, size and height of the chimney all affect the performance of the flue
draught.
Other factors affecting the flue draught include:
Trees or other buildings nearby causing turbulence
High and gusty winds
Outside temperature
Outside weather conditions
Incorrect additional ventilation to building
