Detailed description
Area of application & Target audience
The MPM Wood Plus 26 is a log wood gasification boiler For use in open or closed heating systems according to PN-EN 12828. It is suitable for single-family homes, smaller apartment buildings, workshops and commercial units.
The operation is exclusively with a Buffer storage tank of at least 1000 liters prescribed.
Everyday benefits
The wood gasification principle involves combustion 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 for comfortable log lengths and reduces refueling 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 train regulator
-
Secondary air control
-
Thermometer in the upper area
Manual loading is done with firewood (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 5th grade according to PN-EN 303-5:2021-09.
Seasonal energy efficiency: 79%
Energy efficiency class: A+
EEI: 116
Emissions at rated power:
-
PM: 15 mg/m³
-
OGC: 10 mg/m³
-
CO: 398 mg/m³
-
NOx: 142 mg/m³
This means the boiler meets the current requirements for modern biomass heating systems.
compatibility & System integration
It can be operated in both open and closed heating systems.
Maximum operating pressure: 1.5 bar
Required chimney draft: approx. 0.30 mbar
For continuous operation, a return flow boost (e.g., a 3- or 4-way mixing valve) is recommended.
