Solid fuel boiler with manual loading DEFRO OPTIMA KOMFORT PLUS A 35 kW

Defro Optima Komfort Plus boilers are designed to operate on various types of fuel, including coal, wood, sawdust, and wood chips. The enlarged loading door ensures easy access to all heat exchanger elements, making cleaning and maintenance as convenient as possible.

The PID air injection system evenly distributes the airflow through multi-point air nozzles, increasing fuel combustion efficiency, ensuring combustion stability, and reducing fuel consumption by up to 20%.

Two operating modes:

Top combustion – gradual and even fuel combustion.

Bottom combustion – intensive combustion process with high heat output.

A single fuel load provides up to 24 hours of continuous operation.

Modern technologies in the construction of Defro Optima Komfort Plus

Durable boiler steel – the heat exchanger is made of heat-resistant steel with a thickness of 6 mm, ensuring high strength and resistance to extreme temperatures.

Maximum thermal efficiency – efficiency up to 86%, achieved through:

A four-level convection channel system for efficient heat exchange.

Point air distribution, optimizing the combustion process.

Multi-point air supply, contributing to the stability of the boiler's operation.

Automatic control – the electronic system controls the operation of two pumps (heating and domestic hot water), ensuring comfortable operation.

Easy cleaning – the lower part of the boiler is equipped with a foot pedal, allowing easy cleaning of the combustion chamber due to movable grates.
