What size stove will I need?

The most common Frequently Asked Question - The size of stove you’ll need will of course depend on the age of your home, the size of your room, the number of windows in the room, number of external walls, its insulation, how open plan it is, whether there are any stairs coming off it etc. Most stove manufacturers measure stove size in kilowatts (kw). A rough guide is to measure your room in metres then use the formula below: length (m)  x width (m) x height (m)  / 14. This will give you the KW output required.
