Optima Komfort Plus

The construction of the OPTIMA KOMFORT PLUS BOILERS allows for dual system work and burning any type of fuels - fines when firing up from the top (with combustion support of up to 20 hours) and other solid fuels (coal, wood, fines and coal mixture) when firing up from the bottom.
The boilers feature electronic control of air blow-in into the combustion chamber allowing for more precise temperature regulation increasing operation comfort. The system of multiple-point air blow-in into the area of charged fuel increases stability and efficiency of boiler operation.

Fuel type

primary

substitute

fine coal

nut coal

coal/fine coal

edgings, shavings

Boiler’s advantages:

	4-year warranty for heat exchanger tightness, 2-year warranty for other elements and eficient operation of the boiler;
	the exchanger has been made from certified boiler steel ( P256GH type) of thickness of 6 mm, delivered by the following steel plants: Arcelor Mittal Poland S.A, Kraków branch and U. S. Steel Košice s.r.o.;
	high thermal efficiency, up to 80%, thanks to increased heat recovery from flue gas - multi-draught system of vertical combustion channels;
	electronic control of the boiler; programmer cooperating with 2 pumps (central heating and hot utility water) and with output for a room controller;
	mechanical movable grate for removing ash from water grate bars;
	multiple-point air blow-in into the area of charged fuel;
	big combustion chamber;
	two modes of operation - fired up from the top as a fines boiler (combustion support up to 20h) or as a universal boiler fired up from the bottom (for hard coal of other assortments and wood);
