Solid fuel boiler with automatic loading DEFRO KOMFORT EKO LUX 20 kW

The DEFRO Komfort Eko Lux automatic solid fuel boiler is a reliable alternative to gas and liquid fuel heating systems, offering ease of use and resource efficiency. This model is equipped with an automatic fuel supply system for the combustion chamber and a durable retort burner made of heat-resistant cast iron.

The boiler's heat exchanger is constructed from P265GH Arcelor Mittal steel with a thickness of 6–8 mm, ensuring an energy efficiency (COP) of up to 88%. For thermal insulation, basalt mineral wool is used, preventing the risk of burns in case of accidental contact with the metal surfaces of the housing.

Komfort Eko Lux features an upgraded cast iron burner and a spacious fuel hopper designed for granular fuels such as pellets and coal (5–25 mm fraction). The auger feed mechanism provides automatic fuel delivery, while forced primary air supply ensures stable and efficient combustion. Additional air is evenly distributed through special channels, promoting complete fuel combustion and effective ash removal.

To enhance performance, the boiler includes a multi-point air supply system with an automatic nozzle cleaning function, ensuring uniform combustion and optimizing overall efficiency.

Flue gas removal is carried out through a rear exhaust port, and the built-in damper allows for precise draft regulation, enabling control over the combustion process. The boiler's design facilitates easy maintenance and cleaning of the heat exchanger and exhaust channels.

Operation is managed by the K1 smart controller, which regulates four pumps (heating, domestic hot water, and two additional circuits), a mixing valve, and supports GSM and internet modules, as well as the SPK Lux room thermostat. Controller software updates can be performed via USB by downloading the latest version from the manufacturer's website.

Although DEFRO Komfort Eko Lux is a single-circuit boiler, it can be connected to an indirect water heater, ensuring continuous hot water supply throughout the heating season. A circulation pump speeds up the heating process, and installation is straightforward, allowing for self-assembly or professional setup.
