FAQs
What is the difference between this concentrated fluid and ready-to-use fluids?
Concentrated fluid like the HP-5c requires dilution with water to achieve the desired frost protection level and system fill. Ready-to-use fluids are pre-diluted and can be added directly.
How do I determine the correct dilution ratio?
Always refer to the Fernox dilution guide, which is typically found on the product packaging or the manufacturer's website. The ratio depends on the ambient temperature and the required level of frost protection.
Can I use tap water to dilute the fluid?
No, it is essential to use de-ionised or distilled water for dilution. Tap water contains minerals that can interfere with the fluid's performance and potentially cause scaling or corrosion.
What is the typical lifespan of this heat transfer fluid?
When used correctly and maintained within the system, Fernox heat transfer fluids are designed for long-term protection, often lasting many years. However, periodic checks and system maintenance are recommended.
Is this fluid safe for all types of heating systems?
The HP-5c is specifically designed for Air and Ground Source Heat Pumps and underfloor heating systems. Its compatibility with common system materials ensures safe use in these applications.
How should I handle and store the concentrate?
Handle with care, wearing appropriate personal protective equipment. Store the concentrate in its original, sealed container in a cool, dry place, away from direct sunlight and sources of ignition.
What are the temperature limits for this fluid?
The Fernox HP-5c provides frost protection from -4°C up to -14°C, depending on the dilution ratio used. It also protects against overheating in standard operating conditions for heat pumps and underfloor heating.
Troubleshooting
Fluid level appears low
Check for leaks in the system. If no leaks are found, the system may require topping up with the correctly diluted fluid. Consult system manual.
System is not heating effectively
Ensure the fluid concentration is correct for the operating temperature. Check for blockages or air in the system. Verify pump operation.
Signs of corrosion or scale within the system
Although the fluid is designed to prevent this, ensure the correct dilution was used and that no incompatible materials were introduced into the system. Periodic system flushing may be necessary.
Fluid appears cloudy or discolored
This may indicate bacterial contamination or an incompatible mixture. Consider a full system flush and refill with freshly diluted Fernox HP-5c.
