Biocide F7 prevents bacterial contamination and fungal growth within underfloor, low temperature heating systems and chilled systems. Biocide F7 is also used to clean and prevent the reoccurrence of microbiological fouling producing jelly-like deposits (fungal growths) in feed and expansion cisterns.
Used for my underfloor heating and boiler/cylinder circuits. Seems to work well as no sign of jelly-like deposits and both circuits drain clean. As with most chemicals these days though, it's becoming more expensive, especially as annual replacement is recommended.
