Defro CALORI Pellet Boilers
Defro CALORI boilers are modern, eco-friendly heating units designed for automatic combustion of wood pellets. They are engineered to deliver high energy efficiency and user comfort while meeting the strict emission standards of the Ecodesign directive. With a broad range of outputs, CALORI boilers provide a reliable heat source for various types of buildings.
- Product intended for the Polish market
- Warranty for the Polish market.
Key features of Defro CALORI boilers:
- Automatic pellet combustion: The boiler is designed for automatic operation, using recommended wood pellets or briquettes as fuel, which ensures ease of use.
- High thermal efficiency: The units offer high operational efficiency, exceeding 84% at nominal output, which translates into efficient fuel use.
- Ecodesign compliance: The boilers meet the requirements of Commission Regulation (EU) 2015/1189 (Ecodesign), 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 varied nominal outputs (approximately 11 kW to 30 kW), allowing selection to match a building’s heating demand.
- Automated and efficient operation: The boilers are designed for optimal performance and are recommended to be used with a properly sized hot water buffer tank to maximize system efficiency and stability.
Who is this a good choice for?
Defro CALORI pellet boilers are an excellent choice for owners of single-family homes, both new and renovated, who are looking for a reliable, environmentally friendly and largely maintenance-free source of heat. The wide range of available outputs allows selecting the appropriate model for different building sizes, ensuring thermal comfort while respecting the environment and complying with current standards.
