Defro CALORI Pellet Boilers
The Defro CALORI series boilers are modern and eco-friendly heating devices designed for the automatic combustion of wood pellets. They are engineered to provide high energy efficiency and user comfort while complying with the strict emission standards of the Ecodesign directive. Offering a wide range of power options, CALORI boilers serve as a reliable source of heat for various types of buildings.
Key Features of Defro CALORI Boilers:
- Automatic Pellet Combustion: The boiler is designed to operate in automatic mode, utilizing recommended pellets or wood briquettes as fuel, which ensures ease of use.
- High Thermal Efficiency: These devices feature high operational efficiency, exceeding 84% at nominal power, translating to effective fuel usage.
- Ecodesign Compliance: The boilers meet the requirements of Commission Regulation (EU) 2015/1189 (Ecodesign), characterized by low emissions of dust (PM), carbon monoxide (CO), organic gaseous compounds (OGC), and nitrogen oxides (NOx).
- Wide Power Range: The series includes models with varying nominal power (from approximately 11 kW to about 30 kW), allowing for the selection of a unit that fits the heating demands of the building.
- Automated and Efficient Operation: The boilers are designed for optimal performance, recommending compatibility with a suitably selected hot water buffer tank to maximize efficiency and stability of the heating system.
Who is it a Good Choice For?
The Defro CALORI pellet boilers are an excellent choice for homeowners of single-family houses, whether new or being renovated, who are looking for a reliable, eco-friendly, and largely maintenance-free source of heat. The wide range of available power options allows for selecting the appropriate model for buildings of different sizes, ensuring thermal comfort while respecting the environment and complying with applicable standards.
