We externally audit our wood pellets monthly and receive regular reports, but what do the results mean and how useful are they?
Our monthly results demonstrate our adherence to the ENPlus quality standard. The ENPlus standard is administered in the UK by the UK Pellet Council and is based on EN 14961-2, which brings together numerous European national standards and certifications into one uniform standard.
As commercial buyers, the ENPlus standard is a minimum requirement when purchasing your wood pellets since to ensure compliance with most boiler manufacturer’s warranties and fuel recommendations.
This standard has no less than 22 quality requirements that stipulate the parameters for meeting the standard. These 22 requirements cover everything from the physical dimensions of the wood pellet, and the burning performance to the acceptable levels of sulphur, chlorine, and copper.
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.
