20L Concentrate Heat Pump Fluid

This 20L Concentrate Heat Pump Fluid is a high-performance, glycol-based heat transfer fluid specially formulated for use in air source and ground source heat pumps, as well as underfloor heating systems. It provides excellent frost protection, corrosion and limescale prevention, and helps maintain system efficiency and longevity.

Key Features

• Frost Protection: Protects against freezing from approximately -4°C to -14°C depending on dilution concentration (10% to 30%).
• Corrosion and Scale Prevention: Contains inhibitors to protect metals in heat pump and underfloor heating systems from corrosion, limescale, and bacterial contamination.
• Non-Toxic and Safe: Formulated to be non-toxic and compatible with all commonly used materials in heat pump and underfloor heating installations.
• pH Stable: Maintains chemical stability to ensure long-lasting protection.
• Dilution Required Before Use: Should be diluted with mains or softened water to recommended concentrations for effective protection and performance.

Usage Guidelines

• Minimum in-use concentration: 10%
• Maximum in-use concentration: 30%
• Frost protection examples by concentration:
  • 10% dilution = frost protection to approximately -4°C
  • 20% dilution = frost protection to approximately -9°C
  • 30% dilution = frost protection to approximately -14°C
• Use a refractometer to check fluid concentration in system.
• Before adding the fluid, clean existing systems of sludge, limescale, and deposits for optimal results.
