Defro FIREWOOD Series Wood Log Boilers
The Defro FIREWOOD series boilers are modern heating devices designed for manual loading and burning of wood logs. Engineered for efficient and environmentally friendly heating, they meet the stringent requirements of the Ecodesign directive and achieve a high energy efficiency class of A+. The FIREWOOD boilers provide a reliable source of heat for users who prefer traditional wood fuel.
Key Features of Defro FIREWOOD Boilers:
- Designed for burning wood logs: The boiler is optimized for the efficient combustion of logs with a moisture content of up to 25% when loaded manually.
- High energy efficiency: These units are rated at energy class A+ and have a seasonal energy efficiency for space heating of 80%.
- Compliance with Ecodesign: The boilers meet the requirements of Commission Regulation (EU) 2015/1189, which means low emissions of pollutants, including particulate matter (PM), carbon monoxide (CO), and nitrogen oxides (NOx).
- Various heating powers: The series includes models with nominal heating power of 12, 15, 19, and 24 kW, allowing the boiler to be tailored to the specific heating needs of the building.
- Collaboration with a heat buffer: For optimal operation, compliance with emission standards, and maximum efficiency, it is recommended to operate the boiler in a system with a suitably sized heat storage buffer.
Who is this a good choice for?
The Defro FIREWOOD boilers are an excellent choice for individuals seeking an efficient and eco-friendly wood log boiler with manual loading. They are ideal for single-family homes, where users appreciate traditional fuel and are willing to manage the manual feeding of wood. The necessity of collaborating with a heat buffer makes this a solution for conscious users aiming to optimize the performance of their heating system.
