Wood Pellets

These are made from compressed sawdust that is usually considered waste from sawmills. Hence the name, they’re shaped like pellets and have a shiny finish due to the natural glues usually found in sawdust. 

In order to work in the Effecta Komplett III, The Guntamatic Biostar, Biocom or Powercorn and the Lindner & Sommerauer SL 30 to 150 and SL 199 to 250 your pellets need to:

• Be accredited to the ENPlus A1 or A2 Standard 
• Be 5-30mm long
• Be 5-6mm in diameter 
• Have a water content of 8-10% 
• Have an ash content of 0.5%. 

Pellets that fit these requirements will have a bulk weight of around 650kg/m³ and will produce 4.9kWh of heat per kilogram.

As with all biofuels, we can’t stress enough how important the quality is. To be sure that you’re using the best biofuel, use the Biomass Suppliers List (BSL) to track down trusted suppliers in the Wye Valley and beyond. Concentrating on finding the best supplier is a great way to ensure you have a happy, healthy boiler.

Storage

Keep your pellets in a specifically built store with good access and an inspection hatch. Pellets are usually ‘blown’ in through an external filler tube by a delivery tanker.
