Product Details

In line with BS 7953:2019 regulations and best practice, and for long-term protection of the system, concentration levels should be maintained and checked annually as part of the boiler or system service. Compatible with all other Fernox products and is suitable for use with all materials and metals used in central heating systems, including aluminium.

• Stops frequent venting of radiators

Rated 4 out of 5 by from Clear Water F1 Fernox was put in the system about a year ago for safety and without draining all the water in the system. Drained system again today to put F3 cleaner in to do a complete flush and water ran clear.
