Defro DELTA EKOPELL Pellet Boilers
The Defro DELTA EKOPELL pellet boilers are modern, automated heating devices designed for efficient and environmentally friendly combustion of wood pellets. Meeting the stringent requirements of the Ecodesign directive, they provide high user comfort and reliable heating for a variety of properties, adhering to the high energy efficiency standards of A+.
Key Features of the Defro DELTA EKOPELL Boilers:
- Automatic Pellet Combustion: The boiler is equipped for comfortable and efficient combustion of wood pellets in automatic mode, minimizing the need for manual operation.
- High Energy Efficiency: The devices boast an energy class of A+ and high seasonal heating efficiency (up to 80%), ensuring economical fuel consumption.
- Environmentally Friendly and Compliance with Standards: The boilers meet the requirements of the Ecodesign directive (Commission Regulation (EU) 2015/1189), characterized by low emissions of particulate matter (PM), carbon monoxide (CO), organic gaseous compounds (OGC), and nitrogen oxides (NOx).
- Wide Range of Power Options: The series includes models with rated outputs of 10, 15, 20, 25, and 30 kW, allowing for precise selection of a device matching the specific heating demand of a building.
- Optimal Operation with a Buffer: For the most stable and efficient operation of the heating system, it is recommended to operate the boiler in conjunction with a suitably sized domestic hot water buffer tank (with a capacity of at least 200-600L depending on the model).
Who is this a good choice for?
The Defro DELTA EKOPELL boilers are an excellent choice for owners of single-family homes and smaller commercial properties looking for a modern, efficient, eco-friendly, and largely maintenance-free source of heat. With compliance to the Ecodesign standards and a high energy efficiency rating, they serve as an ideal solution for both newly constructed buildings and those undergoing modernization, where heating efficiency and environmental care are priorities.
