Fernox Cleaner F3 500ml: Restore Your Central Heating System
Your central heating system is essential for home comfort, but sludge, limescale, and debris can reduce efficiency, increase costs, and cause boiler noise. Fernox Cleaner F3 500ml is a high-performance, pH-neutral cleaner that removes these issues, restoring optimal heating performance and extending system life. One 500ml bottle treats up to 130 litres of system water, 16 radiators, or 250m² of underfloor heating, offering a cost-effective solution for homeowners and professionals. Discover why Cleaner F3 is the top choice for central heating maintenance:
- Eliminate Sludge and Limescale Effectively
Sludge and limescale block pipes and impair heat transfer. Cleaner F3’s fast-acting formula clears them out, reducing boiler noise and improving heating efficiency for consistent warmth across all radiators. - Pre-Commissioning for New Systems
For new installations, Cleaner F3 complies with BS 7593:2019 by removing flux residues and debris. This ensures reliable boiler performance from the start and protects your investment for long-term durability. - Achieve Significant Energy Savings
Combine Cleaner F3 with Fernox Protector F1 to gain up to 15% gas savings per heating cycle. This reduces energy bills and minimizes environmental impact, making it an efficient choice for sustainable heating. - Broad Compatibility for All Systems
Cleaner F3 works with all metals and materials, including aluminium, in radiators, underfloor heating, and mixed-metal systems. It’s ideal for both new commissions and revitalizing existing setups. - Enhanced Powerflushing Capabilities
For heavily contaminated systems, Cleaner F3 integrates with powerflushing units, speeding up removal of sludge and limescale. Its non-foaming, pH-neutral design allows easy flushing with minimal disruption. - Environmentally Friendly Formula
