Solid fuel boiler with manual loading DEFRO OPTIMA KOMFORT PLUS A 12 kW

DEFRO OPTIMA KOMFORT PLUS A – economical and powerful long-burning boiler

DEFRO OPTIMA KOMFORT PLUS A is an innovative solid fuel boiler designed for heating private houses and cottages up to 120 m². The model belongs to the new generation of heating systems equipped with an intelligent control unit with a PID controller.

The automatic air supply system with the help of a blower fan controls the combustion process, maintaining a stable coolant temperature not exceeding 85°C. If the set parameters are exceeded, the system reduces the air supply or turns it off, increasing energy efficiency and reducing fuel consumption.

Optimal air distribution by zones contributes to the complete combustion of fuel in different operating modes. The boiler also supports the connection of a temperature sensor for controlling the indirect heating boiler and is compatible with two circulation pumps for heating and hot water supply systems.

Intelligent control system

 - K3P controller with mixing valve control function

 - S3P driver (the ST-28 OPTI PID is used in the 8 kW model)

 - DEFRO-MZ – weather-dependent mixing valve controller

 - Support for additional modules: GSM, Internet

 - KDR 3 NZ version for closed heating systems

Compatibility with various types of fuel

 - Top loading (burning from the top): coal fines.

 - Bottom loading (kindling from the bottom): wood, eco-peas, briquettes, chips, coal.

Main advantages of DEFRO OPTIMA KOMFORT PLUS A

 - High-strength heat exchanger – made of certified heat-resistant boiler steel P265GH (6 mm, Arcelor Mittal, Poland), ensuring durability and resistance to high temperatures.

 - Efficiency (up to 83%) – achieved through thoughtful design and rational use of flue gas thermal energy.

 - Reliable thermal insulation – mineral rock wool is used between the heat exchanger and the casing, preventing burns when in contact with the boiler surface.

 - Mechanical cleaning system – an integrated foot pedal moves special teeth that break the slag crust, improving air supply and combustion efficiency.

 - Movable grate – significantly simplifies the process of removing ash and coke, improving air circulation.

 - Optimized flue gas removal – a special smoke duct with an adjustable damper allows precise control of the chimney draft, affecting the combustion intensity.

 - Ease of maintenance – convenient access to the heat exchanger and chimney simplifies the boiler cleaning process, extending its service life.

Where is it used?

 - Private houses and country cottages

 - Warehouses and production facilities

 - Small commercial buildings

Additional benefits

 - Economy – rational fuel consumption reduces heating costs.

 - Flexibility in operation – the ability to work with various types of solid fuel.

 - Automated control – support for draft regulator and blower system.

 - Safety and durability – thoughtful design and high-quality materials ensure reliable and stable operation for many years.

DEFRO OPTIMA KOMFORT PLUS A is a reliable, modern, and energy-efficient boiler that will provide warmth and comfort in your home!
