Communal Flue System (CFS)

The Atmos Communal Flue System (CFS) is a breakthrough, multi-storey flue system for the UK. Thanks to the  CFS; condensing boilers, which are incompatible with SE ducts typically used on multi-storey buildings, can now be fitted on blocks of flats or similar projects. This ensures that installers, public sector specifiers and developers meet the highest required energy efficiency standard.

Already proven on numerous multi-storey developments in the Netherlands, where condensing boiler technology has been firmly established for many years, the CFS is now available in the UK from Atmos. This innovative system can handle up to 20 boilers on one stack, delivering combustion and providing for the efficient discharge of flue products, thus eliminating unsightly pluming from the side of a building. With the new HSE/CORGI regulations which make horizontal internal flue runs very difficult, the CFS system is a vertical solution which permits the boiler to be located away from the outside wall. Ideal for new build projects, the CFS can also be used as a retrofit solution for developments already equipped with an SE duct system, so enabling standard boilers to be replaced with high efficiency condensing units.

John Thomason, General Manager of Atmos explains: “One of the bug bears with condensing boilers, particularly for local authorities, is that they are incompatible with the ordinary SE ducts typically used on multi-storey buildings making it difficult to take advantage of the technology. However, the Atmos CFS enables the installation of condensing boilers, thereby dramatically reducing the building’s carbon footprint.”

The new CFS brochure from Atmos illustrates the various configurations available, including the naturally vented, or the more compact fan assisted system. The system works with condensing, non-condensing or a mixture, and will add a new flexibility to gas boiler installations in multi storey buildings and therefore contribute to huge carbon savings across the country.
