Useful data 

Wood energy

The amount of energy released by wood is highly dependant upon the moisture content. As a general principle, wood for use as a fuel should be dried as much as possible. We advise that wood-chip is dried and burnt at an average of 30% moisture and should not exceed a maximum of 35%, unless the boiler manufacturers specifies a higher moisture content.

Boiler power  

Older gas and oil boilers are rated in BTU’s. Here are some conversion figures to help change BTU’s in to kW.

Typical chip densities  (Heizohack 30mm chip)

(Useful to know because wood-chip are easier to measure by volume than weight)
