Defro GAMMA Series Pellet Boilers
The Defro GAMMA series boilers are modern, automated heating devices designed for wood pellets, combining high energy efficiency rated A+ with eco-friendly operation in line with Ecodesign standards. Offering a wide range of power outputs, the GAMMA boilers provide comfortable and economical heating for various applications.
Key Features of Defro GAMMA Boilers:
- Automatic Pellet Combustion: The boiler operates fully automatically, utilizing pellets or wood briquettes as the recommended fuel, ensuring high operational comfort.
- High Energy Efficiency (A+): With an energy class of A+ and seasonal heating efficiency for space heating ranging from 79% to 81%, these boilers guarantee economical fuel consumption.
- Compliance with Ecodesign: The devices meet the strict requirements of Commission Regulation (EU) 2015/1189 (Ecodesign) regarding low emissions of pollutants (PM, VOCs, CO, NOx) during pellet combustion.
- Wide Power Range (10-40 kW): Available models with rated power from 10 kW to 40 kW allow for precise matching of the boiler to the thermal demand of buildings of various sizes.
- Optimal Operation with Buffer Tank: Recommended collaboration with a suitably sized hot water buffer tank (minimum capacity depending on the model) to ensure the most stable and efficient operation of the heating system.
- Low Electricity Consumption: The boilers feature low power consumption for their own needs, further reducing operating costs.
Who is this a good choice for?
Defro GAMMA boilers are an excellent solution for homeowners, as well as smaller commercial or public utility buildings, looking for an efficient, eco-friendly, and automated pellet heating system. Their high energy class and compliance with standards make them an ideal choice for those who value savings, operational comfort, and care for the natural environment.
