The Fernox F7 Biocide (200ml) is designed for homeowners and heating engineers to prevent bacterial growth, sludge, and blockages in central and underfloor heating systems, ensuring optimal efficiency and preventing costly breakdowns. While highly effective, it should be used in conjunction with corrosion inhibitors like Fernox Protector F1 for complete system protection. This powerful biocide offers fast-acting disinfection and preservation, maintaining clean system water and improving circulation for consistent heating performance.

The frequency of use depends on the system. For general maintenance and prevention, it's often used during annual system servicing or when topping up the system. For systems with known issues, follow professional advice or product instructions for initial treatment and subsequent maintenance.
Fernox F7 Biocide is specifically designed to be compatible with Fernox Protectors. While it may be compatible with other brands, it is recommended to use it with Fernox inhibitors for guaranteed performance and system safety.
When stored correctly in its original container, in a cool, dry place, Fernox F7 Biocide typically has a shelf life of several years. Refer to the product packaging for specific expiry dates.
Signs include reduced heating efficiency, increased noise, blockages, and visible slime or deposits in feed and expansion cisterns. Low-temperature systems, like underfloor heating, are more susceptible to bacterial growth.
No, Fernox F7 Biocide primarily targets bacterial and fungal growth. For protection against corrosion and scale, it must be used in conjunction with a suitable Fernox system inhibitor, such as Protector F1.
A biocide (like F7) kills microorganisms that cause fouling and blockages. A system inhibitor (like F1) prevents corrosion and scale formation within the heating system's metal components.
Fernox F7 Biocide is designed for closed-loop heating and chilled systems. It is not intended for use in domestic hot water systems.
Ensure the correct dosage was used for the system volume and that the system has been circulating adequately. For severe contamination, a second application may be necessary, or professional advice should be sought.
The existing deposits may be extensive. Try to manually remove as much as possible and then re-apply Fernox F7 Biocide. Consider a full system flush if the problem is severe and persistent.
Check that the biocide is circulating properly. Ensure the dosage is correct for the system size. If issues persist, the problem might be due to factors other than microbial growth, such as pump performance or thermostat settings.
