Why Is My Stove Making An Unexpected Noise?

Some wood or solid fuel stoves can produce unexpected noises from time to time, and is sometimes considered part of the charm of owning a wood burning stove.

Whistling

Whistling is a result of the air needed for combustion entering the stove through restricted airways and across sharp or angular edges. It is usually caused by high flue draughts above 20 pa (pascals). With a flue draw above 30 pa the whistling (if it occurs) can be quite loud, this can be resolved with the installation of a flue dampener or flue stabiliser. Whistling is also more common on stoves with tertiary air inlets. Increased flue draught (above 20 pa) can also reduce the overall efficiency of the stove by around 3-4%, and result in a more rapid consumption of fuel together with a decrease in the heat output to the room.

Clicking

On occasion you may hear a 'clicking' noise from the stove, this can be due to the varying rates of thermal expansion whilst the different gauge of metals used in construction will expand and contract at different rates during heating up and cooling.It is most often heard when a stove is cooling down from quite a high burn rate. It can continue for some time, and is more commonly heard on smaller stoves.
