The MPM Wood Plus 26 is a modern wood gasification boiler with a nominal output of 26 kW for log wood. It meets the requirements of Class 5 according to PN-EN 303-5 as well as the Ecodesign Directive and achieves energy efficiency class A+. Ideal for single-family homes with buffer tank operation.
Highlights / Benefits
⭐ 26 kW nominal output – ideal for single-family homes and commercial units
⭐ Class 5 & Ecodesign – low emissions and high environmental compatibility
⭐ Energy efficiency class A+ (EEI 116) – economical operation
⭐ Generous loading chamber (~120 dm³) – long burn time of up to approx. 6 hours
⭐ Operation in open or closed system possible
Detailed description
Area of application & target group
The MPM Wood Plus 26 is a log wood gasification boiler for use in open or closed heating systems in accordance with PN-EN 12828. It is suitable for single-family homes, smaller multi-family homes, workshops and commercial units.
Operation is only permitted with a buffer tank of at least 1000 liters .
Everyday benefits
Thanks to the wood gasification principle, combustion takes place in two separate chambers – degassing of the wood and subsequent clean afterburning in the ceramic combustion chamber.
The result:
The large loading chamber (~120 dm³) allows comfortable log lengths and reduces reloading intervals.
Technology & equipment
The boiler is manufactured as a welded steel construction and features:
-
movable cast iron grate
-
ceramic burner
-
vertical heat exchanger channels with turbulence unit
-
mechanical draft regulator
-
secondary air control
-
thermometer in the upper area
Manual loading is carried out with log wood (moisture content ≤25 %).
Recommended operating temperature: 60–90 °C
Minimum return temperature: 55 °C
Efficiency & environment
The MPM Wood Plus 26 meets the Ecodesign Regulation (EU) 2015/1189 as well as the Class 5 according to PN-EN 303-5:2021-09.
Seasonal energy efficiency: 79 %
Energy efficiency class: A+
EEI: 116
Emissions at nominal output:
-
PM: 15 mg/m³
-
OGC: 10 mg/m³
-
CO: 398 mg/m³
-
NOx: 142 mg/m³
The boiler thus meets the current requirements for modern biomass heating systems.
Compatibility & system integration
Operation is possible in open or closed heating systems.
Maximum operating pressure: 1.5 bar
Required chimney draft: approx. 0.30 mbar
For permanent operation, a return temperature control (e.g. 3- or 4-way mixing valve) is recommended.
