Defro DELTA EKOPELL Pellet Boilers
The Defro DELTA EKOPELL pellet boilers are modern, automatic heating units designed for efficient and environmentally friendly wood pellet combustion. Complying with the strict Ecodesign requirements (Commission Regulation (EU) 2015/1189), they provide high user comfort and reliable heating for a variety of buildings, meeting A+ energy class standards.
- Product intended for the Polish market
- Warranty for the Polish market.
Key features of Defro DELTA EKOPELL boilers:
- Automatic pellet combustion: The boiler is configured for comfortable and efficient automatic wood pellet burning, minimizing the need for user intervention.
- High energy efficiency: The units hold an A+ energy class and offer high seasonal space heating efficiency (up to 80%), ensuring economical fuel consumption.
- Eco-friendly and standards-compliant: The boilers meet Ecodesign requirements (Commission Regulation (EU) 2015/1189), featuring low emissions of particulate matter (PM), carbon monoxide (CO), organic gaseous compounds (OGC) and nitrogen oxides (NOx).
- Wide power range: The series includes models with nominal outputs of 10, 15, 20, 25 and 30 kW, allowing precise selection to match a building’s heat demand.
- Optimal operation with a buffer: For the most stable and efficient heating system performance, it is recommended to operate the boiler together with a suitably sized buffer tank for domestic hot water (minimum capacity 200–600 L depending on the model).
Who is this a good choice for?
Defro DELTA EKOPELL boilers are an excellent option for owners of single-family homes and smaller utility or commercial buildings who are looking for a modern, efficient, eco-friendly and largely low-maintenance heat source. Thanks to Ecodesign compliance and a high energy class, they are ideal for both new constructions and renovated buildings where heating efficiency and environmental care are priorities.
