Energy Saver F6 is an additive designed to improve the efficiency of central heating systems by reducing nucleated boiling bubbles and smoothing flow surfaces. It works by laying down long chain molecules in the system. While it improves efficiency, it does not provide antifreeze or corrosion protection like Fernox's heat transfer fluids, so it must be used with a Fernox Protector F1 inhibitor. Energy Saver F6 can save up to 1.2% of energy consumption annually on a scaled boiler and 0.8% on an unscaled boiler.

Questions and answers
What is Energy Saver F6?
Fernox Central Heating Energy Saver F6 is an
innovative new chemical water treatment product.
Independently tested, Energy Saver F6 has been
developed to improve heat transfer efficiency and
contribute to lower energy usage within traditional
central heating systems.
Is it available in other formats such as
Superconcentrate gels or aerosols?
The Energy Saver F6 is currently available as a
500 ml liquid product only.
Does it differ from a renewable heat transfer
fluid such as Solar S1, or the HP range? If so,
how does it differ?
Energy saver is a 500 ml additive product which
treats 100 litre system. It is specifically designed
to improve the efficiency of heating systems
and does NOT provide antifreeze and system
protection like Solar S1 or HP Heat Transfer
products.
How does Energy Saver F6 work?
The performance improvement arises as a result
of laying down long chain molecules within the
heating system. This has a dual effect of reducing
the size of nucleated boiling bubbles that form
on the heat exchanger (which add an additional
insulation layer to the heat exchanger surface)
and smoothing the internal flow surfaces of the
heating system, thereby reducing drag.
