Stove Size Calculator

Please use the calculator below to give you an idea of the suggested stove output size for the room where the stove is to be installed. Choosing a multifuel stove with the correct output is critical. Buy one that is too small and you will be forever disappointed with its performance, buy one thats too large and you will either never enjoy it fully, or use far more fuel than you need, overheating the space. A fire with the right output will be much more controllable, always providing a comfortable environment.

We always recommend a survey, as other factors may warrant a slightly larger multi fuel stove such as open doorways into other rooms, draughty gaps in doors and window frames and wooden floors with large voids beneath, these can all affect the size of stove required for a particular room.
