Pellet Burner DOMNA ECO 22 kW

DOMNA ECO-22 Pellet Burner is a technologically advanced heating device from TechnoMaszBud, dedicated to users who value efficient and comfortable heating as well as energy independence.

The 22 kW power output is an optimal solution for single-family homes or smaller commercial or industrial facilities.

The DOMNA ECO-22 burner is equipped with an automatic ignition system, a precision controller, and an effective self-cleaning mechanism. As a result, the DOMNA ECO-22 burner allows for almost maintenance-free heating.

The automatic control system eliminates the need for constant supervision, and the efficiency of up to 98%—which is particularly important nowadays—guarantees real savings.

Principle of Operation

Pellets from the tank are fed to the burner via a screw feeder, where they are ignited on the grate. The blower fan supplies air in a controlled amount, enabling efficient combustion. The heat generated in the burner is transferred to the boiler, where it heats water circulating in the heating system.

The entire process is supervised by an advanced controller from PLUM, which manages the air supply to the combustion chamber, pellet feed, and water temperature.

The set includes:

• Domna ECO-22 Burner
• Controller with a set of sensors
• Screw feeder Ø63 x 1700 mm
• Pipe Ø50 x 1000 mm
• Operating manual
• (Optional: rotary safety valve)

Main Advantages of the DOMNA ECO-22 Pellet Burner

• Ceramic combustion chamber in all burner models – ensures complete and high-quality fuel combustion thanks to the formation of a thermal core. The heat is not transferred to the burner's chamber, thus not damaging it, but remains inside the combustion chamber, acting as a sort of catalyst for full fuel combustion. The flame from such a chamber becomes cleaner, and the amount of ash and clinkers from low-quality fuel is reduced.
• Cast iron grates with a lifetime warranty – can confidently be called "eternal"—they do not burn out or deform at high temperatures, unlike grates made of stainless steel or ordinary steel. Cast iron grates perfectly retain the high temperature produced by the ceramic combustion chamber and work in tandem with it exceptionally well.
• Cascade Cleaning System (CCS) – the cascade self-cleaning system for grates distributes fuel evenly over the entire combustion area. It allows operation on low-quality pellets and effectively removes ash and other combustion residues. Cascade cleaning has been recognized on the market and by most device manufacturers as the most efficient and reliable. This very system is used in all Domna burner models.
• Clever Air System (CAS) – an intelligent system for distributing primary and secondary air and proportional mixing with fuel, allows for maximum combustion efficiency (98%) and stable operation. The system enables the combustion of pyrolysis (pellet) gases released during pellet burning, which reduces fuel consumption and minimizes harmful emissions into the atmosphere.
• Ceramic igniter FKK (Japan) – the best igniters available on the market. They work quickly, are very reliable, and offer a long service life—over 10,000 ignitions.
• ESC (Easy Service Cleaning) – enables easy access to the combustion chamber and burner grate block for service inspections and cleaning, with no special tools required. The system allows the burner chamber to be cleaned without opening the boiler door, which is convenient and saves time and effort.
• Fuzzy Logic – intelligent automatic modulation system for the burner output.
• Modern control system – enables management of the heating and domestic hot water systems via the internet or a mobile app, with advanced weather-based smart control – all easily accessible with Domna burners.
• DSS (Domna Safety System) – a multi-stage burner safety system, which ensures operation is pleasant and safe. Complies with all fire protection standards for solid fuel combustion.
• Low emissions – thanks to its ceramic combustion chamber, cast iron grates, and CAS system, Domna burners emit significantly fewer harmful exhaust gases (CO, NOX, OGC) and dust into the atmosphere compared to burning in solid fuel boilers or burners lacking these features.
• The quietest pellet feeder – the screw for feeding pellets is made of high-quality plastic, making the transport process virtually silent. It also has a reduced friction coefficient, so pellets are not crushed into dust and are delivered to the combustion chamber intact. This helps solve the problem of excessive dust during combustion.
• Easily replaceable combustion chamber made of heat-resistant AISI 310S steel.
• Long service life of burners – thanks to components from premium global brands: Siemens, Lapp, Plum, MplusM.
• Automatic restart – automatic start and return to preset operating mode after a power outage.
• Warranty – 24 months

Applications for the DOMNA ECO-22 Burner
