The size and output of your stove will of course depend on the size of your room and its insulation. Most stove manufacturers will quote output in KWs. A rough guide is to measure your room in metres then use this formula. length x width x height. This will give you the cubic meterage, and then divide by 14 to give you the KW output required
From our experience one 5 kw stove heating a room for a winter season will use about 2 loads of good seasoned hard wood (this year a load is around £90 – £100) The better the quality of wood the less you will use and of course how much you use your stove will also affect your wood usage as will the length of the season!
Unseasoned wood All logs should be seasoned – that is cut, chopped and left to air – for at least 12 months to allow the moisture level to drop to around 18 – 20%. Investing in a moisture meter is a good idea . Incorrect use of airwash Most wood-burning stoves now come with an airwash system to discourage soot from settling on the glass. You should try to avoid closing the airwash vent completely when the stove is in use or the glass will blacken. Fuel touching the glass If the glass is blackening in just one or two areas rather than across its entire surface, it might be that you are overloading the stove or loading fuel too close to the glass, causing the fuel to burn against the glass.
All logs should be seasoned for at least one year, hardwoods are the best such as Ash, Beech, Birch, Poplar, Oak, Elm. (What woods to Burn ) or telephone us for our list of local recommended wood suppliers 01483 727534.
