Wood Pellet Heaters
Wood pellet heating systems use a renewable fuel and can be an alternative to oil and gas, particularly in existing buildings. Whether they are the right solution depends on the specific conditions of the house and the long-term availability of the fuel.
How a Pellet Heater Works
Wood pellet heating systems work similarly to oil or gas heating systems. Heat is generated by burning wood pellets, which are made from compressed sawdust. The heat is then distributed throughout the house via the heating system.
Unlike heat pumps, the efficiency of pellet heating systems depends much less on the required heating temperatures. For this reason, they can often replace existing oil or gas heating systems without requiring extensive renovations or the replacement of radiators. This can be a particular advantage for historic homes.
Using Wood Wisely
Wood is a renewable resource, but its availability is limited, and it is needed in many sectors.
Using it as a building material or in the furniture industry also has the advantage that CO₂ is sequestered in the wood for many years or even decades. If the pellets are sourced from sustainable and, whenever possible, regional forestry operations, or produced from wood industry waste, they still represent a climate-friendly heating option.
Due to these competing uses, fluctuating or rising prices for wood pellets are to be expected in the long term. In addition, maintenance requirements and costs are comparatively high. Whether a pellet heating system is the right solution should therefore always be evaluated on a case-by-case basis for each building.
