Automatic boiler Defro Komfort Eko LUX 25 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 used, e.g. a cooling valve DBV-2. 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 touch panel (additionally supports heating system components). It is possible to purchase a GSM or INTERNET module, which gives us control over the boiler outside the home.

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

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

Flue gases are discharged into the chimney through a damper 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 closed and sealed furnace-ash pan doors. Additionally, on the front of the boiler there are cleaning doors - depending on the boiler 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 surroundings using an external casing made of steel sheets, under which thermal insulation made of asbestos-free mineral wool is placed.
