STAINLESS STEEL HEAT EXCHANGER

The employees of “Italtherm” designed a stainless steel heat exchanger with an extremely high water flow capacity: the internal part of the heat exchanger was increased by 4 times compared to other competitors.

Thanks to the new heat exchanger, “City Class” has better heat transfer and provides better protection against heat exchanger scaling, making “City Class” condensing boilers ideal for replacing boilers in old systems.

The design of the new heat exchanger ensures:

high flow
low hydraulic load losses
easy cleaning and technical maintenance of the boiler.

ICS - AUTOMATIC COMBUSTION SYSTEM

The engineers of “Italtherm” developed the “ICS – automatic combustion system”, which turns the “City Class” boiler into a smart boiler that automatically controls, adjusts, and adapts.

“ICS – automatic combustion system” controls combustion parameters and regulates gas flow so that the boiler always receives the correct air-to-gas ratio, thus achieving:
