What it is

The Fernox F3 Cleaner is a central heating system cleaner classed as a cleaner consumable, supplied by Fernox under part number 56600. It is designed to be added to heating system water to help remove sludge and debris from radiators, pipework and boiler heat exchangers during a system clean.

Before you order

  • Confirm the system is a sealed central heating system before use, as cleaners are dosed into system water.
  • Check the product label and manufacturer instructions for the correct dosing and flushing procedure.
  • Consider whether a magnetic filter or inhibitor is also required for the system once cleaned.
