High Turndown, Full Modulation

Condensing Boilers

Condensing boilers achieve high efficiency by using the waste heat in the flue gases to pre-heat the cold water entering the boiler.

High-efficiency condensing boilers designed both for retrofit and new construction projects. Project costs are reduced thanks to the high water content heat exchanger, that requires no minimum flow rate and eliminates the need of a costly dedicated boiler circulator. Best quality materials used for all components guarantee high reliability and longer service life.
Condensing boiler technology is the most efficient and environmentally friendly form of fuel heating available today. Condensing technology recovers the condensation heat retained latently in flue gases, that is a part of energy that normally disappears up the chimney in other heating systems. Thanks to lower fuel consumption and lower heating costs, condensing boilers usually pay for themselves in few years, reducing costs up to 20% in comparison with conventional heating. Additionally, a modern condensing heating system increases the value of the building as well as quality of life by reducing emissions. High efficiency condensing equipment achieves qualifying points for LEED certification of commercial buildings.
