Automatic boiler Defro Komfort Eko LUX 15 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, it can be installed in a closed heating system, with a working pressure not exceeding 2.5 bar provided that thermal protection is applied, e.g. 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 supports heating system installation components). It is possible to purchase a GSM or INTERNET module, thanks to which we have supervision over the boiler outside the home.

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

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

Flue gases are discharged to the chimney through the flue located in the rear or top wall of the boiler (CG version). For loading purposes and periodic cleaning and maintenance, the boiler is equipped with sealed and insulated burner-ash pan doors. In addition, cleaning doors are located on the front of the boiler - depending on the boiler's power, single or double.

The fuel tank is equipped with a filling 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 casing made of steel sheets, under which thermal insulation made of asbestos-free mineral wool is placed.
