RTC is a high water content condensing boiler for installation in heating plants. It is suitable for heating systems and production domestic hot water, in combination with a suitable storage cylinder.
Boiler with three effective flue gas passes. All parts in contact with the combustion products are titanium stabilized stainless steel. Designed based on principle of heat stratification. This allows operation no limits on the return water temperature, maximizing flue gas condensation, for very high efficiency.
The combustion chamber located up high and the tube bundle below, with smooth pipes and removable turbulators. This creates a countercurrent water-flue gas flow, optimizing heat exchange and energy efficiency.
Furthermore, the furnace size is designed to obtain very low polluting emissions values, when combined with Riello BLU flame burners.
