Welcome to our comprehensive category of Boiler Flues, where we cater to all your boiler flue requirements. Our range includes products from renowned vendors like Vaillant and Heatline, offering a variety of options to suit different boiler models and installation environments.

Vertical and Horizontal Flue Kits

We offer a range of vertical and horizontal flue kits, perfect for standard boiler installations. These kits come in various sizes and lengths, ensuring compatibility with different boiler models and installation spaces. Whether you need a standard horizontal flue kit or a more specific vertical option, we have you covered.

Elbows and Bends

Our selection includes elbows and bends in various angles such as 45 and 87 degrees. These are essential for navigating around obstacles in your installation space and ensuring a safe and efficient exhaust path for your boiler.

Extensions and Adaptors

For more complex installations or to bridge larger distances, our range includes flue duct extensions and adaptors in various lengths and diameters. These are designed to extend your flue system to the required length, ensuring effective exhaust dispersion.

Roof and Wall Terminals

To ensure safe and compliant termination of your boiler flue, we provide a selection of roof and wall terminals. These are designed to safely vent out the exhaust gases while protecting your installation from weather elements.

Support and Fixing Accessories

We also offer a variety of support and fixing accessories like adjustable support clips, security fixing brackets, and penetration collars. These accessories ensure a secure and stable installation of your flue system.

Specialised Kits

For specific use cases, we have specialised kits like the variable termination kit, telescopic flue duct extensions, and remote PRV mounting kits. These specialised products cater to unique installation requirements and offer additional flexibility and customization.

Product Selection Guide

When selecting the right boiler flue product, consider the following:

  • Boiler Model Compatibility: Ensure the product is compatible with your boiler model.
  • Installation Environment: Consider the space and layout where the boiler and flue will be installed.
  • Regulatory Compliance: Make sure the selected products comply with local building and safety regulations.

     

Our range of boiler flues and accessories ensures that you can find the perfect fit for your boiler installation needs, providing efficiency, safety, and compliance.
