Fernox F2 Boiler Noise Silencer is a specialist treatment that reduces boiler noise and kettling caused by scale deposits inside heating systems. By improving heat transfer, it helps calm noisy boilers quickly. As a result, it supports smoother operation while you plan further maintenance if needed.
If your boiler rumbles, bangs, or makes kettling sounds, scale build-up often causes the issue. These deposits create hot spots inside the heat exchanger. Therefore, treating the system water with a purpose-made product like Fernox F2 can quickly reduce noise and restore calmer performance.
What Is Fernox F2 Boiler Noise Silencer?
Fernox F2 is a liquid treatment that targets the symptoms of boiler noise and kettling. It works with all boiler types, including combi boilers and systems containing aluminium components. As a result, it suits a wide range of domestic central heating systems.
Fernox also confirms that installers can leave the product in the system permanently. This provides ongoing support against recurring boiler noise without disrupting normal operation.
What Causes Boiler Noise and Kettling?
Scale deposits commonly cause boiler noise and kettling. These deposits restrict heat transfer inside the heat exchanger. When heat cannot move away evenly, localised hot spots develop. This process creates the familiar rattling or “kettle” sound.
Treating the symptoms early helps restore quieter boiler operation. However, Fernox F2 does not replace full system cleaning where sludge or debris exists. For this reason, Fernox recommends cleaning the system first and then adding an inhibitor to protect long-term performance.
