Solid fuel boiler with automatic loading DEFRO KOMFORT EKO LUX 30 kW

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

The Defro Komfort Eko Lux is an automatic solid fuel boiler that combines ease of use with energy efficiency, making it a reliable alternative to gas and liquid fuel heating systems. It is equipped with an automatic fuel delivery system to the combustion zone and a durable 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 basalt wool, placed between the heat exchanger and the casing, as well as in the doors of the combustion chamber. This eliminates the risk of burns when touching the external metal parts of the boiler.

Komfort Eko Lux features an innovative cast iron burner and a spacious hopper for bulk fuels such as pellets or coal with a fraction of 5–25 mm, allowing the boiler to operate autonomously for up to 3–5 days. The burner has a bowl-shaped design where the combustion process takes place. Fuel is delivered to the combustion chamber automatically via a screw conveyor, while forced primary air supply ensures stable combustion and prevents burner overheating.

Additionally, secondary air is supplied to the combustion zone through special openings in the boiler's design. This promotes complete fuel combustion, and the resulting ash is automatically removed by new fuel portions.

To enhance the boiler's efficiency, a multi-point air supply system with a nozzle cleaning function is used. The directed airflow into the combustion zone ensures uniform and prolonged fuel burning, stabilizing the device's operation.

Exhaust gases are vented through a 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 is optimized for easy maintenance – cleaning the heat exchanger and flue is quick and hassle-free.

The boiler is controlled by a modern weather-dependent controller, which manages four pumps (heating, hot water supply, and two additional circuits), a mixing valve, and supports the connection of GSM and internet modules for remote control. Additionally, it is possible to connect the SPK Lux room thermostat. The controller's firmware can be updated via USB 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 year-round. The use of a circulation pump speeds up the heating system's warm-up. The installation process is simple and does not require significant effort, so it can be done either independently or with professional assistance.
