Heat Output Example


Often a stove is chosen to match the fireplace, hearth or style of room it is to be fitted in. However the most important factor in choosing the right size stove is getting the right output to ensure you will not be too hot! The formula for doing this is to measure the room volume (width x length x height) in metres and divide this by 14.


A well-insulated room, central heating, double glazed window – 5kW recommended.

Draughty room, old windows, wooden floor – 7kW recommended.

The examples above show a room as described in the example but with different furnishing and heating with the recommended stove outputs for each.

These recommended outputs would be the nominal or CE rated outputs of the stoves. Most stoves have a wide output range allowing flexibility for you heating needs.
