Defro FIREWOOD series log boilers
The Defro FIREWOOD series boilers are modern heating appliances designed for manual loading and burning of split wood. Engineered for efficient and environmentally friendly heating, they meet the stringent standards of 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 split wood: The boiler is optimized for efficient combustion of wood logs with moisture content up to 25% when manually loaded.
- High energy efficiency: The units feature 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 heat outputs: The series includes models with nominal heat outputs of 12, 15, 19 and 24 kW, allowing selection to match a building’s heating needs.
- Works with a buffer tank: For optimal operation, emission compliance and maximum efficiency, it is recommended to use the boiler as part of a system with an appropriately sized thermal buffer tank.
Who is this a good choice for?
The Defro FIREWOOD boilers are an excellent choice for people looking for an efficient and eco-friendly manual-load log boiler. They are well suited for single-family homes where users appreciate traditional fuel and are prepared to handle manual refueling. The need to operate the boiler with a buffer tank makes this a solution for informed users aiming to optimize their heating system’s performance.
