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.
