The Woodlets team pride themselves on delivering high quality wood pellets when you want them, in a professional manner but how can you confirm the quality of the wood pellets?
There have been a number of wood pellet quality standards in use around the world and gradually they have been rationalised and now ENPlus is the leading standard. Most boiler manufacturers insist that you use ENPluspellets to keep your warranty intact. So what is ENPlus and what does it mean?
The ENPlus standard is administered by the UK Pellet Council and it adheres to the European standard EN 14961-2. The standard sets out specific quality and performance criteria that the pellets need to meet to enable them to carry the ENPlus logo.
In all, there are 22 quality requirements that pellets must comply with. These include the physical properties of the pellet such as bulk density (measured in Kg/m3) and fines (small or broken pellets) and sets out parameters for moisture and as well as the maximum levels of trace elements such as sulphur, chlorine, copper, lead and mercury.
Critically it includes a minimum net calorific value, which is the measure of the amount of energy you are buying and a maximum ash content, to ensure that once the pellets have been through your boiler you are left with the smallest possible amount of ash to dispose of.
It also sets limits for additives used as a binding agent to make the pellets stick together. Woodlets don’t use any additives as they are potentially damaging to your boiler.
