The most important certification for quality pellets that are burnt in households is EN plus A1. This is the highest quality class. It sets the strictest requirements for calorific value, ash content and other parameters.

As we fulfil all requirements anyway, we also have other certifications, such as DIN EN ISO 17225-2, the Ecolabel, etc. However, quality only comes into play when competent and trained personnel deliver the pellets cleanly and blow them in gently.
