Automatic boiler Defro Komfort Eko LUX 25 kW with feeder on right side

The boiler KOMFORT EKO LUX is a boiler from the Komfort Eko series, designed for installation in an open heating system, can be installed in a closed heating system, with a working pressure not exceeding 2.5 bar provided that thermal protection is used, e.g. DBV-2 cooling valve. System protection should meet the requirements of standards PN-EN-12828 and PN-EN 303-5.

The boiler KOMFORT EKO LUX has been equipped with an advanced K1Pv4 controller with a color touchscreen panel (additionally supports heating system components). It is possible to purchase a GSM or INTERNET module, which allows you to monitor the boiler outside the home.

The furnace also has an innovative solution, which is the ABM system, an energy-efficient geared motor (power consumption 30W) with high efficiency and auto-reverse in case of fuel feeder blockage.

The combustion chamber is equipped with an automatic retort burner. In the flue ducts there are economizers (flue gas swirlers), designed to increase boiler efficiency and reduce flue gas emission levels. Fuel for the combustion process is transported automatically from the fuel tank located nearby by means of an Archimedean screw feeder.

Flue gases are discharged to the chimney through a flue located in the rear or upper wall of the boiler (CG version). For loading purposes and periodic cleaning and maintenance, the boiler is equipped with closed and sealed combustion chamber and ash pan doors. Additionally, cleaning doors are placed in the front of the boiler - depending on the boiler power, single or double.

The fuel tank is equipped with a filler hatch with a sealed closing mechanism. It has a flap opening sensor, which protects against leaving the fuel tank cover open. To reduce heat loss, the external surface of the boiler is insulated from the environment using external cladding made of steel sheets, under which thermal insulation is placed made of asbestos-free mineral wool.
