Solid fuel boiler with manual loading DEFRO OPTIMA KOMFORT PLUS A 25 kW

Defro Optima Komfort Plus – versatile boilers for efficient heating

Defro Optima Komfort Plus boilers are designed to work with various types of fuel, including coal, wood, sawdust, and wood chips. Thanks to the enlarged loading door, convenient access to all parts of the heat exchanger is provided, which significantly simplifies the cleaning and maintenance process.

The boiler is equipped with a PID air supply system, which distributes the airflow through multi-point air nozzles. This contributes to increased fuel combustion efficiency, stable burning, and up to 20% fuel savings.

The model supports two operating modes:

Top combustion – even fuel burning.

Bottom combustion – more intense combustion process.

One fuel load is sufficient for up to 24 hours of continuous operation.

Innovative design of Defro Optima Komfort Plus

Defro Optima Komfort Plus boilers are a combination of modern technology and reliability. The heat exchanger is made of durable 6 mm boiler steel, which guarantees durability and resistance to high temperatures.

High efficiency (up to 86%) is achieved thanks to:

Four levels of convection channels, ensuring efficient heat exchange.

Pointed air supply system, improving the combustion process.

Multi-point air supply system, stabilizing combustion.

The electronic control system allows the control of two pumps – for heating and hot water supply.

At the bottom of the boiler, a foot pedal is installed to facilitate cleaning of the combustion chamber due to the movable grates.
