The most important things in brief

Sustainability: Pellet systems use wood pellets as a renewable energy source and are CO₂-neutral.

Efficiency: High efficiency and automatic fuel supply ensure comfortable heating operation.

Subsidies: State funding programs support the switch to pellet heating systems with attractive subsidies.

How does a pellet system work?

Pellet systems burn wood pellets in a burner to generate heat for heating and hot water. The burning process is fully automatic.

• Fuel supply: Pellets are automatically transported from a storage container to the burner.
• Combustion: The burner ignites the pellets and generates heat.
• Heat utilization: The heat generated is transferred to the heating system via a heat exchanger.
