CASE STUDY
In a large naval base in the South, three large boilers ended their useful life…sadly so did the old existing twin wall insulated flue system. SFL key customer FBS Flues & Chimneys was appointed to design, supply and install new flue systems to complete the project.
Installation Partner
"The complete installation was finished in a single day and within budget, focusing on quality and safety. The SFL NOVA® twin wall system was selected as it's combined with a high performance / high-density insulating medium, provides the optimum level of performance required for the Hoval Ultragas 400 gas-fired boiler."
Paul Fox, SFL
On the arrival of three new highly efficient Hoval Ultragas 400 gas-fired boilers technicians set to work to connect water and electric feeds. SFL key customer FBS Flues & Chimneys was appointed to design, supply and install new flue systems to complete the project. After the site survey, a specialist “SFL I-size” flue design calculation was completed, this determined the flue diameter flue required to allow the boilers to work safely and efficiently.
Test points were included to allow ongoing regular flue gas analysis. SFL’s SUPRA PLUS® was utilised for the initial internal connections, changing to 300mm dia NOVA® Nova twin wall insulated flue, before penetrating the external wall drain points were provided for rain and condensate removal whilst providing protection from freezing weather. Offsets were incorporated into the flue risers to clear protruding soffits and gutters.
The complete installation was finished in a single day and within budget, focusing on quality and safety, FBS Flues and SFL a winning team. FBS Flues specialise in the supply and installation of commercial design & build chimney systems and are able to offer a full package covering detailed site survey, flue size calculations, design, and CAD drawing services working in partnership with SFL product range.
