Boiler Flue Extensions are crucial components for residential and commercial heating systems, designed to safely transport exhaust gases from the boiler to the outside of the building. The offerings in this category include a variety of extensions suitable for different boiler models and installation requirements.

Vaillant Flue Extensions

Vaillant, a leading brand in the market, provides an array of flue extensions compatible with their EcoTec range. These extensions come in standard sizes of 100mm and 125mm, ensuring a snug fit for the respective boiler models. Whether you're extending the flue horizontally or vertically, these components ensure safe and efficient emission of gases.

The Vaillant telescopic Ecotec Flue Duct Extensions, available in lengths like 440mm and 690mm, offer flexibility in installation, especially in spaces where standard lengths don't fit. Moreover, the Vaillant Termination Kit complements the flue system by providing an essential 1m extension along with a termination piece, available in various colours to match the building's exterior.

Heatline Flue Extensions

Heatline presents a practical solution with their 60/100mm Air/Flue Duct Extensions, catering to a different set of boiler models. These extensions are available in multiple lengths, accommodating a wide range of installation scenarios. They are an excellent choice for those needing a narrower diameter extension.

Selection Guidance

Choosing the right flue extension depends on several factors:

  • Boiler Model: Ensure compatibility with your specific boiler model.
  • Diameter Requirements: Match the diameter of the extension to the existing flue system.
  • Length Necessity: Measure the distance needed to safely route the flue to the outdoors.

  • Telescopic Options: Consider telescopic extensions for adjustable fitting.

     

Selecting the appropriate extension is not just about fitting and measurements; it's also about adhering to safety standards and regulations. Always consult with a certified heating engineer to ensure a proper and secure installation.
