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 eco-friendly heating, they meet the stringent standards of the Ecodesign directive and achieve a high energy efficiency rating of A+. The FIREWOOD boilers provide a reliable source of heat for users who prefer traditional wood as a fuel.
Key Features of Defro FIREWOOD Boilers:
- Designed for burning wood logs: The boiler is optimized for the efficient combustion of wood logs with moisture content up to 25% through manual loading.
- High energy efficiency: These devices have an energy class rating of A+ and a seasonal energy efficiency of heating rooms at 80%.
- Compliance with Ecodesign: The boilers meet the requirements of the Commission Regulation (EU) 2015/1189, ensuring low emissions of pollutants, including particulate matter (PM), carbon monoxide (CO), and nitrogen oxides (NOx).
- Variety of heating outputs: The series includes models with nominal thermal outputs of 12, 15, 19, and 24 kW, allowing the boiler to be tailored to the individual heating needs of the building.
- Collaboration with a heat buffer: To ensure optimal operation, compliance with emission standards, and maximum efficiency, it is recommended that the boiler be used in conjunction with a suitably selected heat buffer tank.
Who is it a good choice for?
Defro FIREWOOD boilers are an excellent choice for those seeking an efficient and eco-friendly wood log boiler with manual loading. They are ideal for single-family homes where users value traditional fuels and are prepared for the maintenance associated with manual wood replenishment. The need to work in conjunction with a heat buffer makes this a solution for conscious users aiming to optimize their heating system’s performance.
