Optima Plus

The OPTIMA PLUS boiler series is an upgraded version of OPTIMA boilers. State-of-the-art, electronic control of air blow-in into the combustion chamber significantly increases the comfort of operation, increases combustion time and allows for even more precise temperature control. The system of multiple-point air blow-in into the area of charged fuel increases stability and efficiency of boiler operation.
The heat exchanger, made from P265GH boilerplate, has a significant impact on durability of the boiler and is insulated with mineral wool and covered by steel sheets.

Boiler’s advantages:

	3-year warranty for heat exchanger tightness, 2-year warranty for other elements and efficient 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 (not applicable for 10 and 13 types);
	wide range of power;
	big combustion chamber;
	multiple-point air blow-in into the area of charged fuel;
