MPM Wood Plus 6 kW wood gasification boiler

Area of ​​application & Target audience

The MPM Wood Plus 6 is a water-bearing wood gasification boiler with manual feeding for logs (moisture content ≤ 25%).
It is particularly suitable for:

• Single-family homes

• small residential buildings

• Workshops or commercial premises with low heating requirements

The system operates exclusively at nominal power in conjunction with a buffer storage tank.

---

Everyday benefits

The carburetor technology ensures a two-stage combustion:
First, the wood is degassed, then the resulting wood gases are completely burned in a ceramic combustion chamber.

The result:

• stable combustion

• low emissions

• high efficiency

• Burning time up to approx. 4 hours per filling

With a fuel consumption of approximately 1.5 kg/h, the boiler operates economically and in a resource-saving manner.

---

Technology & equipment

The MPM Wood Plus 6 is made of certified steel boiler plate in a welded construction.
The construction includes:

• large loading chamber (~30 dm³/approx. 10 kg wood)

• movable cast iron grate

• Metal-ceramic burner

• vertical flue gas ducts with turbulence element

• mechanical tension regulator

• Thermometer in the upper boiler area

• DBV-1 connection for thermal overheating protection

Thermal insulation is provided by 40 mm of mineral wool.
