Komfort Eko

The EKO KOMFORT boilers feature a combustion chamber equipped with highly effective retort furnace charged with fuel automatically. The KOMFORT EKO boiler has a dFIX system allowing for double-side installation of any fuel charger manufactured by PW DEFRO. Moreover, the boiler has been equipped with a cast iron supplementary grate, which allows for temporary usage of other fuels as well as using the device in emergency cases.
The exchanger has been made from certified boiler steel of thickness of 6 mm. For higher level of usage safety, the boiler has been equipped with a fuel-container door sensor, which checks if the door is always hermetically closed while the boiler operates.
Attachable and adjustable legs and flue extension with draught regulator are standard equipment of the boiler. Upon request, the boiler can also be equipped with a system of automatic water quenching protecting against flash-back into the fuel charging system.
