Fernox Biocide F7 is designed to protect low temperature or underfloor heating circuits from bacterial contamination and fungus in domestic central heating and non-evaporative chilled water systems.


These types of heating systems are at higher risk from bacterial slimes, algae and biofilms forming, which can cause blockages. This can result in sluggish, less efficient system performance or even breakdown.

Developed to treat 150 litres of system water or 280m2 of underfloor pipework, Biocide F7 protects and maintains system efficiency.

• Prevents the reoccurrence of jelly-like deposits in feed and expansions cisterns

• Simple application
