Product details
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 have been engineered to provide high energy efficiency and user comfort while meeting the strict emission standards of the Ecodesign Directive. Offering a wide range of power outputs, CALORI boilers are a reliable source of heat for various buildings.
Key Features of the Defro CALORI Boilers:
- Automatic Pellet Combustion: The boiler is designed to operate automatically, using recommended pellets or wood briquettes as fuel, which ensures ease of use.
- High Thermal Efficiency: These devices boast high operational efficiency, exceeding 84% at rated power, leading to effective fuel utilization.
- Compliance with Ecodesign: The boilers meet the requirements of Commission Regulation (EU) 2015/1189 (Ecodesign), characterized by 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 varying rated power (from approximately 11 kW to 30 kW), allowing for the selection of a unit that meets the thermal demand of the building.
- Automated and Efficient Operation: The boilers are designed for optimal performance, recommending collaboration with an appropriately selected hot water buffer tank to maximize efficiency and stability of the heating system.
Who is this a good choice for?
The Defro CALORI pellet boilers are an excellent choice for homeowners of single-family homes, whether new or undergoing modernization, who are looking for a reliable, eco-friendly, and largely maintenance-free source of heat. The wide range of available power outputs allows for the selection of the appropriate model for different building sizes, ensuring thermal comfort while respecting the environment and complying with applicable standards.
