Advance Boiler Protection Kit

Correct water quality and treatment is of paramount importance to a healthy heating system, by installing a filter as one of the measures ensures our products offer optimal performance with dirt-free water.

Designed by Vaillant and manufactured to our very own specification, the new Advance boiler protection kit is more compact, but the 12,000-gauss magnet provides strong magnetite removal capabilities.

Available as a 22mm variant, the filter fits horizontally onto the pipework, meaning it can be fitted into tighter spaces, and is designed to be fitted close to the bottom of the boiler, making it a more discreet solution.

The Advance Boiler Protection Kit comes with a 10-year manufacturers’ guarantee.

What's in the box

The Vaillant Advance Boiler Protection Kit comes with an installation and operational manual, and isolation valve.

  • It's compatible with the complete range of domestic boilers
  • The Simple Flue can be extended to the maximum permissible length indicated in the manual using our existing ranges of extensions, bends and elbows
