Wood Pellets

Wood pellets are made of sawdust produced as a waste product from sawmills. As suggested by the name, when sawdust is compressed it produces a pellet shape with a shiny finish, due to the natural glues found in sawdust.

In order to work in the Lindner & Sommerauer your pellets need to:

• Be accredited to the ENPlus A1 or A2 Standard 
• Be 5-40mm long
• Be 5-6mm in diameter 
• Have a water content of 8-10% 
• Have an ash content of 0.5%. 

Provided you acquire the correct pellets they will have a bulk weight of around 650kg/m3 and will produce 4.9kWh of heat per kilogram.

We may have mentioned this before but… we can’t stress enough how important the quality is. Only use HETAS/WOODSure suppliers. To be sure of quality use the Biomass Suppliers List (BSL) to track down trusted suppliers all over the UK Concentrating on finding the best supplier is a great way to ensure you have a happy, healthy boiler.

Storage

Your pellets need to be kept in a  specifically built store with convenient access for delivery and an inspection hatch for weekly checks. Pellets are usually ‘blown’ in through an external filler tube by a tanker.
