Defro Gamma 20 kW 5 class boiler

DEFRO Gamma pellet feeder boiler, 5th class and EcoDesign certificate with automatic cleaning function

RELEVANT INFORMATION

The 5th class pellet boiler by DEFRO from the Gamma series with a power output of 20 kW is a central heating pellet cooker with an automatic burner cleaning function, ideal for heating small areas. Its small dimensions make it a great choice for small and inconspicuous boiler rooms. It is an option for all those who appreciate maintenance-free boiler operation.

Extremely easy use of the Defro Gamma 20 kW boiler is enabled by the built-in APC K SLIM controller, which seamlessly communicates with the boiler. As standard, the DEFRO Gamma boiler is equipped with a so-called weather sensor, and the control system allows its expansion and the possibility of adding an additional room controller and an Internet module (non-standard options). The nominal thermal efficiency ranging from 91 to 94% also guarantees lower fuel consumption. An advantage of the DEFRO Gamma series boiler is its compact design. The burner and feeder are built under the pellet hopper. This means that there are no protruding elements from the boiler, which also makes it easier to install the boiler in small boiler rooms.

The DEFRO Gamma 20 kW boiler is a good solution for those users who are looking for an inexpensive yet efficient heating device with an automatic burner cleaning function. The appliance is EcoDesign certified and has a Class 5 emission certificate.

The manufacturer provides the following warranty conditions: 5 years for the tightness of the heat exchanger, 2 years for other components and the efficient operation of the boiler.
