Wood chips are produced from a wide range of sources such as forestry timber, forest co-products, agricultural thinning, short rotation coppice, reclaimed timber and sawmill residues.
They can be significantly cheaper than fossil fuels and are most economical if sourced locally. Wood chips are suited to automatically-fed larger systems of 30kWh or more. Wood chips stored dry can be held for several years with little degradation of quality or loss of energy value.

Wood moisture (dry basis) 18%, 25%, 33%, 43%
Conversion Factors:
1 litre of heating oil generates 2.676 kg CO2
1 litre of heating oil corresponds to 2.5 kg of wood
1 kg wood chips (w = 30 %) generates 3.4 kWh 1000 Litres of Heating Oil Corresponds to:
Approx 5 - 6 rm hardwood, stacked log wood
Approx 7 - 8 rm softwood, stacked log wood
Approx 10 – 15 srm wood
Explanations and Abbreviations:
1 srm = 1 m3 of poured wood (loose)
1 rm = 1 m3 of stacked split wood (stere)
1 fm = 1 solid metre of wood (without gaps)
