Automatic boiler Defro Komfort Eko LUX 40 kW with feeder on left side

The boiler KOMFORT EKO LUX is a boiler from the Komfort Eko series, intended for installation in an open heating system, it can be installed in a closed heating system, with working pressure not exceeding 2.5 bar provided that thermal protection is applied, e.g. DBV-2 cooling valve. Installation 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 touch panel (additionally controls heating system components). There is a possibility of purchasing a GSM or INTERNET module, thanks to which we can monitor the boiler outside the home.

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

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

Flue gases are discharged to the chimney through flue pipe located in the rear or upper wall of the boiler (CG version). For loading purposes and for 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 boiler power, single or double.

The fuel tank is equipped with a filling opening with a sealed closing mechanism. It has a flap opening sensor, which protects against leaving the fuel tank cover open. To reduce heat losses, the external surface of the boiler is insulated from the surroundings by means of external steel sheet casing, under which thermal insulation made of asbestos-free mineral wool is placed.
