Wood Pellet Fuel

What are wood pellets?

Wood pellets are cylindrical in shape and made from compressed sawdust, which is often the waste product from the timber industry (e.g. sawmills) They are fused by the natural lignin present in dry wood. It strengthens the wood as well as having water proofing properties.

Pellets have a very low moisture content, which helps consistent combustion efficiency, as during the burning of fuel, any water content must be evapourated before combustion can occur. This process requires energy, and therefore reduces overall system efficiency. Pellets are additionally very dense. Both these qualities make them a good source of energy.

Only approved wood pellets can be used. For further details, please click here.

Renewable fuel 

As the sawdust is a waste product e.g. from sawmill industries, or has been sourced from a managed forest (i.e. where trees are planted to replace the ones cut down), wood pellets are classed a renewable carbon neutral source of fuel.

How are pellets delivered?

Wood pellets can be bought in bags (various sizes but typically around 10kg), or alternatively they are delivered in bulk load (around one to five tonnes at a time) by tanker and blown into the hopper through a flexible hose. Buying pellets in bulk works out far less expensive than in bags.
