British-Built Condensing Boiler Flue Systems From SFL

Flue Systems For Condensing Boilers

Condensing appliances are compact efficient solutions to suit many commercial plant rooms, ranging from hotels, stadiums and residential care homes. Flue design is extremely important with condensing appliances due to the volume and acidity of the condensation itself. Correct falls and traps on condensate drains are a key part of the flue design.

 

Important Considerations

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

  • Reduce pooling
    Correct flue design with falls between 3-5% for effective draining of condensate to reduce pooling.
  • Condensate drains
    Condensate drains to have traps to avoid affecting flue draught.
  • Test points
    The system must incorporate test points into the flue.
