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.
