Gas condensing boilers

Clean combustion means minimal pollutants and a clean environment. But clean combustion also means saving fuel. That is why all ITALTHERM boilers are equipped with the ICS (Intelligent Combustion System) with automatic power graduation 1:10.

This system constantly monitors the combustion quality and coordinates the electronic gas valve and the inverter fan, so that the ideal air/gas combustion ratio is always achieved and ensures perfect clean combustion in all operating conditions.

Italtherm boilers are equipped with the new generation of high-efficiency "single stainless steel tube" combustion chambers without connections, have 4 times larger internal water circulation cross-section than that of classic boilers, eliminating the formation of deposits.
