Fernox F2 Express Central Heating Boiler Noise Silencer - 400ml

Boiler Noise Silencer F2 is designed to reduce boiler noise and kittling which is a symptom of a scaled system. It is ideal for use with all types of boilers and is compatible with all metals and materials commonly used in systems including aluminium.

One aerosol (400ml) will protect a 130 litre system or up to ten single radiators and is added via a radiator or filling loop. Fernox Boiler Noise Silencer F2 Express can be dispensed directly into a radiator air vent or system filling loop using the appropriate special adapter supplied with the product. The whole process takes less than two minutes. Too much treatment will not cause problems and is preferable to insufficient dosing. Severe noise may require more than one application. For long term protection against the effects of corrosion and limescale we recommend systems are cleaned using Fernox Cleaner F5 Express and inhibited with a Fernox Protector F1 Express. In single feed indirect cylinders, e.g. ‘Primatic’ or similar, potable water chemicals must be used.
