Product description

• Effective cleaning agent for heating systems

Fernox F3 is a universal cleaning agent with a neutral pH, designed for comprehensive cleaning of central heating systems. It removes sludge, scale, deposits and post-installation contaminants, restoring system efficiency and eliminating unwanted noise. It is ideal for both new installations – removing soldering residues – and older ones, where contaminants have accumulated during operation. Thanks to its formula, the preparation is safe for all metals commonly used in heating systems, including aluminum.

Application and effects

Fernox F3 is a solution for both professional installers and end users. It can be used to clean systems of various capacities – one 500 ml package is sufficient to clean systems up to 130 liters of water, corresponding to 16 radiators or 250 m² of underfloor heating. Regular use of the preparation allows maintaining high energy efficiency of the heating system and can contribute to reducing heating costs by up to 15% (in combination with Fernox Protector F1 corrosion inhibitor). The preparation is also recommended by reputable heating appliance manufacturers, which confirms its effectiveness and safety.

Characteristic features and how to use

• Neutral pH: Safe for all system components, does not cause corrosion.
• Non-foaming: Facilitates flushing and eliminates the risk of problems with circulation pumps.
• Versatility: Suitable for use in new and existing installations, as well as with flow flushing devices.
• Ease of use: It can be added through the expansion tank (in open systems) or through a dedicated dosing point (in closed systems).
• Long-lasting action: In the case of heavily sludged installations, the preparation time can be extended up to a week in a normal heating cycle.

Before using the preparation, drain the system and fill it with water. After adding Fernox F3, flush the system at least twice until the water is clean. For full corrosion protection, it is recommended to use Fernox Protector F1 after cleaning.
