Defro FIREWOOD series wood log boilers
The Defro FIREWOOD boilers are modern heating units designed for manual loading and combustion of wood logs. Built for efficient and environmentally friendly heating, they comply with the Ecodesign directive and achieve a high A+ energy efficiency rating. FIREWOOD boilers provide a reliable heat source for users who prefer traditional wood fuel.
- Product intended for the Polish market
- Warranty for the Polish market.
Key features of Defro FIREWOOD boilers:
- Designed for burning wood logs: The boiler is optimized for efficient combustion of logs with moisture content up to 25% when hand-loaded.
- High energy efficiency: The units have an A+ energy class and a seasonal space heating efficiency of 80%.
- Ecodesign compliant: 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 outputs: The series includes models with nominal thermal outputs of 12, 15, 19 and 24 kW, allowing the boiler to be matched to the specific heating needs of a building.
- Works with a thermal buffer: To ensure optimal operation, compliance with emission standards and maximum efficiency, it is recommended to operate the boiler together with a properly sized thermal buffer tank.
Who is this a good choice for?
Defro FIREWOOD boilers are an excellent choice for those looking for an efficient and eco-friendly wood log boiler with manual loading. They are well suited to single-family homes where users appreciate traditional fuel and are willing to manage the manual refilling of wood. The requirement to use a thermal buffer makes this a solution for informed users seeking to optimize their heating system’s performance.
