Boiler Noise Silencer F2 is designed to reduce boiler noise and kettling and restore heat transfer capability. Boiler noise is a symptom of a scaled system caused by limescale forming inside the pipework. This product is ideal for use with all types of boilers and is compatible with all metals and materials commonly used in systems, including aluminium. The Fernox Express range uses Barrier Pressure Pack technology and compressed air propellant to expel the product, so the entire range is non-flammable. The propellant (compressed air) is not mixed with the active product, so there is no risk of air ingress into the system, which could accelerate the future risk of corrosion.

Please always refer to the manufacturer’s instructions for the correct application. All parts should be fitted by a qualified plumber.
