The instantaneous Infinity gas hot water heaters, divided into an internal and an external range, represent the latest technology in the production of domestic hot water. Compared to traditional systems, Infinity Condensing is able to considerably reduce energy consumption: thanks to the double internal exchanger, which re-uses part of the combustion's latent heat present in the fumes to preheat inlet water with a significant increase in thermal performance. Standing out for its extremely compact size, like all the Infinity range, and its increased thermal efficiency, Infinity Condensing water heaters are capable of producing from 26 to 32 l/min depending on the model.
