Solid fuel boiler with automatic loading DEFRO KOMFORT EKO LUX 15 kW

Automated Solid Fuel Boiler DEFRO Komfort Eko Lux – A Reliable Alternative to Gas and Liquid Fuel Heating Systems

The DEFRO Komfort Eko Lux is an automated solid fuel boiler that combines ease of use with energy efficiency, making it a reliable alternative to gas and liquid fuel heating systems. It features an automatic fuel delivery system to the combustion chamber and a retort-type burner made of heat-resistant cast iron.

The boiler's heat exchanger is constructed from high-strength, heat-resistant P265GH Arcelor Mittal steel, 6–8 mm thick, achieving an efficiency of up to 88%. The insulation layer is made of mineral wool based on basalt fiber, which eliminates the risk of burns when touching the external metal parts of the casing.

Komfort Eko Lux is equipped with an advanced cast iron burner and a spacious fuel hopper designed for bulk fuels such as pellets or coal with a fraction of 5–25 mm. Thanks to the screw conveyor fuel delivery and forced primary air supply, stable and even combustion is achieved. Secondary air is supplied through special channels, promoting complete fuel combustion and efficient ash removal.

To enhance the boiler's performance, a multi-point air supply system with a self-cleaning nozzle function is implemented. This ensures uniform combustion and optimizes the device's operation.

Exhaust gases are vented through a flue pipe located at the rear of the boiler. Draft is regulated using a built-in damper, allowing control over the combustion intensity. The boiler's design simplifies the cleaning of the heat exchanger and flue channels.

The boiler is controlled by the modern K1 controller, which manages four pumps (heating, hot water supply, and two additional ones), a mixing valve, and supports the connection of GSM and internet modules, as well as the SPK Lux room thermostat. The controller's firmware can be updated via USB by downloading the latest version from the manufacturer's official website.

Although the DEFRO Komfort Eko Lux is a single-circuit boiler, it can be connected to an indirect heating boiler to provide hot water throughout the heating season. The use of a circulation pump speeds up system heating, and the installation process is straightforward – it can be done either independently or with professional assistance.

Key Advantages of DEFRO Komfort Eko Lux:

5-year warranty on the heat exchanger's tightness and 2 years on other components.
