The Fernox Heat Transfer Fluid HP-5c is designed for Air and Ground Source Heat Pumps and underfloor heating systems, offering essential protection against corrosion, limescale, and bacterial contamination. While it provides excellent frost protection down to -14°C, users should be aware that it is a concentrated fluid and requires proper dilution based on system requirements and desired frost protection level.

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.
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.
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.
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.
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.
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.
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.
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.
Ensure the fluid concentration is correct for the operating temperature. Check for blockages or air in the system. Verify pump operation.
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.
This may indicate bacterial contamination or an incompatible mixture. Consider a full system flush and refill with freshly diluted Fernox HP-5c.
