Domestic H&V Product of the Year

Fernox – Energy Saver F6

Domestic HV Product of the Year Fernox

Independently tested to verify its ability to improve heat transfer efficiency and contribute to lower energy usage within central heating systems, Fernox’s Energy Saver F6 is the first chemical water treatment that will enhance a system’s efficiency, rather than merely maintain it.

Designed to be used in conjunction with an inhibitor, it treats systems of up to 100 litres, or 10 single-panel radiators, with a payback period of one year.

Energy Saver F6 works on the same principle as fuel improver additives, successfully used in the automotive industry for many years, and was developed by the Fernox research and development team.

The new product was developed after extensive testing and utilises long chain polymers within the heating system that reduce the size of nucleated boiling gas bubbles and smooth the system’s internal surfaces. The benefits have been tested by two independent organisations.
