'Pellet Heating

Pellet Heating means the use of

Types

Basically there are two different operating systems for pellet heating systems. One being single ovens with direct heat release into the living space and the other being central heating systems (pellet central heating systems) including control and feedback control systems.

Pellet stove

Pellet stoves or single ovens are generally plants in the power range of max. 6-8 kW and less. They are usually placed directly in the living room. They usually have a small reservoir of pellet fuel which can last for one or more days. Fuel supply and the control of combustion are controlled automatically and the ash removal is done manually. The heat is usually delivered directly into the room. The range of individual pellet stoves is similarly diverse as wood burning stoves, including versions with viewings window which provide a view of the fire.

Pellet boilers

Pellet boilers are used as central heating systems for heat requirements (heating load) of more than 3.9 kW (Kilowatt). But pellet central heating systems are not only used in single or two family homes (up to 30 kW), but also for larger residential or business units with heat requirements of a few hundred kW. Pellet burner systems run most efficiently at full load and can usually be regulated down to up to 30% of its full capacity. Since the warm up phase of pellet ovens usually takes longer than for oil or gas firing systems, short burning phases have negative effects on the fuel efficiency. In order to improve energy efficiency and reduce harmful emissions, pellet ovens are usually combined with buffer systems like water tanks for example.[1]

Add-on furnaces

Separate pellet burner, which can be mounted to an existing oil- or wood-fired boiler, are sometimes offered as an inexpensive alternative to a complete heating changeover. But the efficiency of these add-on furnaces is reduced. Usually add-on furnaces are not subsidied by government funds.
