By drying the wood chips to 20% water content (W20), the calorific value is increased enormously up to around 4000 kWh per ton. Or in other words: in a burning process of one ton of dried wood chips approx. 400 l of heating oil can be substituted. For wood chip boilers, dry wood chips equate to higher efficiency, clean and more even combustion that in turn ensures trouble-free operation and a long-lasting lifetime of the heating system.Established and run by Henry Fox and employing a highly qualified team of arboricultural specialists, Brendon Hill Tree Services manage all aspects of woodland management and conservation from the base near Taunton.
