DEFRO Gamma boiler with pellet feeder (automatic), class 5 and EcoDesign certificate

IMPORTANT INFORMATION

The 5th class DEFRO pellet boiler from the Gamma series with a power of 25 kW is a central heating pellet stove with an automatic burner cleaning function, ideal for heating small areas. Its small dimensions make it a great choice for small and awkward boiler rooms. This is an offer for all those who value maintenance-free operation of the boiler.

Extremely easy use of the Defro Gamma 25 kW boiler is made possible by the built-in APC K SLIM controller, which communicates seamlessly with the boiler. As standard, the DEFRO Gamma boiler is equipped with the so-called weather sensor, and the control system allows for its expansion and the possibility of adding an additional room controller and an internet module (non-standard options). Nominal thermal efficiency ranging from 91 to 94% also guarantees lower fuel consumption. The advantage of the DEFRO Gamma series boiler is its compact design. The burner with feeder is built under the pellet basket. This means that there are no protruding elements from the boiler, which also facilitates the installation of the boiler in small boiler rooms.
