British-Built Unitary Radiant Flue Systems From SFL

Flue Systems For Unitary Radiant Heaters

High-level gas-fuelled radiant tube heaters are an efficient way to provide space heating and spot occupancy heating in much taller commercial and industrial buildings. Although in an application where spot heating is specified the heaters can be installed unflued with the necessary high- and low-level ventilation, in the majority of modern installations

Unitary Radiant Tube Heaters have individual flues exiting vertically through the roof. In applications where the heaters are wall-mounted, they usually exhaust horizontally through the wall.

With the latest “black globe” radiant thermostats, the radiant tube in shot burner will have enhanced high/low or modulating control to minimise fuel consumption, this could in certain instances produce exhaust products condensation within the flue.

 

Important Considerations

Performance of the appliances can be significantly affected by incorrect flue design and many other factors including:

  • Flue system support
    All radiant tube heaters expand, contract and move in use and will be hung on chains, the flue system should be self-supporting and have a well-engineered joint design.
  • Flue diameters & range
    Most radiant tube flue systems are 80, 100 and 130mm dia, these diameters are set on product approval and should always be used.
  • Knowledge & safety are key
    SFL work in partnership with radiant tube manufacturers ensuring that our flue and ancillaries are perfectly matched to exhaust the products safely and efficiently.
