Fuel Quality
HETAS, in association with The Biomass Energy Centre, have
produced a fuel leaflet with advice to choosing and drying wood logs. Click on the image to read the leaflet in full.

When choosing wood for burning there are two significant factors which have an effect on the heating value of the fuel:
1. Moisture content
2. Wood density
The moisture content of wood has by far the greatest effect on heating value. Any water in the timber has to evaporate away before the wood will burn, and this will reduce the net energy released as heat. More information on wood as a fuel can be found in the guide as above.
You should always take care to burn only dried (seasoned) wood. HETAS now sell useful moisture meters that can be used to quickly identify the moisture content of wood logs, with the European standard being less than 25% for ready to burn firewood.
For good indication of the moisture content of the whole log and heating value, split the log first and probe in a number of places on the frshly split surface.
The moisture meter has a compact design, is easy to operate and has an auto shut off function.
Contact 0845 634 5626 or email info@hetas.co.uk to purchase your moisture meter, currently priced at £16.80 inclusive of VAT and postage.
