What Stove size (KW output) do I need for my home?

Many stoves are chosen on their physical size to match an existing hearth or opening but this has little relationship to the heat requirement of the room.  Notwithstanding variations in heat loss in individual properties, as a general rule you will need 1KW of heat for every cubic metre.  This is based on a room temperature of 21 degrees Celsius at an ambient of -1 degree Celsius.  For example, an average living room measuring 2.3m x 4.9m x 4.7m divided by 14 would require a stove with a nominal output of 4KW.
