Automatic boiler Defro Komfort Eko LUX 30 kW with feeder on left 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 working pressure not exceeding 2.5 bar provided that thermal protection is applied, e.g. a cooling valve DBV-2. 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 installation components). It is possible to purchase a GSM or INTERNET module, thanks to which we can monitor the boiler outside the home.

The furnace also has an innovative solution in the form of the ABM system, an energy-efficient motor-reducer (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 gas passages, economizers (flue gas swirlers) are installed, 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 using an auger 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 for periodic cleaning and maintenance, the boiler is equipped with closed and sealed combustion-ash doors. In addition, the front of the boiler has cleaning doors - depending on the boiler power, single or double.

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