The FCX condensing boiler has specially designed "condensing" chambers manufactured out of High Molybdenum Stainless Steel which extract almost all the heat from the fuel and reduce flue gases to such a low temperature that only a polypropylene flue pipe is required. Fuel consumption and CO2 emissions are reduced, on average, by a third.

The FCX is a dual circuit boiler providing one circuit for the hot water and one for the heating. Our FCX.E2 model allows for two separate heating circuits working at different temperatures as well as the hot water circuit.

The FCX can be equipped with the G8 digital weather compensating controller/programmer, enabling automatic control of temperatures on one heating circuit and hot water circuits directly from the boiler. In this way, the boiler will operate at maximum efficiency throughout the year giving precise comfort levels at minimum running cost.
