Pellet stoves

Heating with biomass in the form of pellets offers both environmental and economic benefits - and of course full heating comfort. Pellet stoves can cover the entire residential heat and hot water needs of your home. They can also be easily integrated into existing heating systems.

Pellet stoves are highly modern systems that guarantee maximum safety and effectiveness.

The advantages of a pellet heating system:

  • Favourable operating price
  • Heating with renewable resources
  • CO₂ neutral heat source
  • Fully automatic controls
  • Good combination possibilities with other renewable energy sources
  • Retrofitting measures are not usually necessary

How pellet stoves work

Heat is produced with pellets instead of oil or gas. This is used to heat the water in the heating circuit. But first, a combustion process must be initiated to produce heat in the first place.

In pellet stoves everything runs by itself: Everything is controlled automatically, from the air and fuel intake to the adaptation to the required heating load up to the burner modulation. So you will always benefit from the optimal operation condition with high efficiency.

Well-thought-out care and control of a pellet stove

1. The pellets are transported via a conveyor system from the storage room to the boiler or to the storage container. A burn back protection system protects against fire contact with the stockpiled fuel.

2. A feed auger then transports the pellets via a chute into the combustion chamber where they are automatically ignited by a hot air blower. The amount of pellets fed depends on the required heat. A lambda oxygen sensor takes over the control of the fuel and air supply and thus ensures energy-efficient and clean burning.

3. The water in the heating circuit is heated.

4. The pellets burn almost completely, so that the ash content of wood pellets is only about 0.5%. Very little ash and fly ash accordingly falls into the two-piece ash container of our pellet boiler. Emptying the ash hopper is only usually necessary every few weeks or months. The bio-ash can then be used as fertiliser in the garden, or disposed of with the household waste.

Pellet feed

The pellets can be fed to the pellet stove either by hand or automatically by auger or suction conveying. Which of the two automatic variants is most suitable for you mainly depends on the distance from the stove to the storage room. Suction conveyance is recommended for storerooms not directly connected to the stove. Pellets can cover a distance of up to 25 meters by suction. They can be drawn directly into a reservoir integrated into the stove to then be automatically conveyed by means of an auger into the combustion chamber.

If the storage area is in close proximity to the pellet stove, you can use the auger, which is characterised by a quieter operation and lower investment costs. In the semi-automatic solution a larger storage container is located on the stove, which is filled by hand and can take up to a week's or month's supply of pellets.

The storage and delivery of pellets

Various options are available for the storage of the pellets. Convenience and the room conditions determine which method is best for you – whether in pellet storage in the building, bag silos or manual loading. Basically pellets should be stored dry in a separate room. In many cases, the design of rooms in homes is such that only a very small investment is required for the transformation of a storage room.

You can assume that wood pellets have to be delivered at similar intervals as heating oil or LPG: One kilogram of wood pellets has about the same heating value as half a litre of heating oil.
