Precisely now, in times of climatic crisis, pellet boilers are one of the best options for protecting the environment. The pellets consist of pressed wood pulp.

The advantage of this heating process is that when the pellets are burnt, just the same amount of CO₂ is released as the tree from which the pellets are made has absorbed from the atmosphere over the years. This means that normal CO₂ levels are not altered by this form of heating.

This CO₂ value significantly increases with other forms of heating, since fuels such as oil or coal when burnt also emit CO₂ but they have not absorbed this CO₂ from the atmosphere beforehand because they were, for example, stored underground.
