Defro Firewood Plus 12 kW carburetor.

Defro Firewood Plus 12 kW log boiler – Powerful and efficient

Modern carburetor system with electronic control

The Defro Firewood Plus 12 kW is a log boiler with an integrated gasification system and electronic draught regulator, designed for maximum efficiency. Thanks to precise primary air control, combustion can be optimally regulated, resulting in consistently high heat output with low fuel consumption.

The control system can also control the boiler circuit pump and an optional induced draft fan to further optimize operation. This provides you with fully automatic control, increasing comfort and significantly reducing the effort required for manual intervention.

Compact design and sustainable heat source

With its compact dimensions, the natural draft boiler fits into almost any boiler room, saving space. Its robust construction ensures a long service life and reliable operation for many years.

As a sustainable alternative to fossil fuels, the boiler uses only logs and meets the strict requirements of BlmSchV Stage 2. This makes it not only climate-friendly but also crisis-proof in terms of heat supply.

Comfortable operation and maximum safety

The standard safety heat exchanger allows installation in closed systems without complex thermal discharge protection. An integrated sight glass allows visual inspection of the carburetor flame, further simplifying handling.

The secondary air supply is accessible from both sides of the boiler, allowing the boiler to be installed close to a wall. This saves space while still providing maximum operating convenience.

Installation, commissioning and service

Delivery is by truck with a tail lift, delivered to the curb. Upon request, we offer nationwide installation and commissioning by our expert customer service team. This means your new heating system is immediately ready for use and optimally adapted to your needs.
