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 on the inside of 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 propellent to expel the product so the entire range is non-flammable. The propellent (compressed air) is not mixed with the active product so there is no risk of air ingress into the system which could accelerate future risk of corrosion.
