Reliance 22mm Heatguard Underfloor Heating Thermostatic Blending Valve.
Reliable Temperature Control for Water Underfloor Heating
The Reliance 22mm Heatguard Underfloor Heating Thermostatic Blending Valve is designed to regulate the water temperature supplied to wet underfloor heating systems. By blending hot water from the heat source with cooler return water from the heating circuits, it provides a stable flow temperature that helps your system operate safely and efficiently.
Maintaining the correct water temperature is essential for protecting floor coverings, improving comfort and ensuring reliable system performance. The Heatguard valve automatically responds to changes in water temperature, delivering accurate control without requiring manual adjustment during normal operation.
Suitable for both domestic and light commercial installations, this valve is an excellent choice for new underfloor heating systems or when replacing an existing blending valve.

Typical Applications
The Reliance Heatguard blending valve is suitable for:
- Water underfloor heating systems
- Domestic heating installations
- Home extensions
- New build properties
- Renovation projects
- Air source heat pump systems

Why Use a Thermostatic Blending Valve?
Water leaving a boiler is often much hotter than is suitable for underfloor heating. The blending valve mixes hot flow water with cooler return water before it enters the manifold, ensuring the water supplied to the floor circuits remains at a safe and efficient temperature.
This helps:
- Improve occupant comfort
- Protect floor finishes
- Increase energy efficiency
- Reduce temperature fluctuations
- Extend the lifespan of the heating system

Frequently Asked Questions
What does the Reliance 22mm Heatguard blending valve do?
The Reliance Heatguard blending valve mixes hot water from your heat source with cooler return water from the underfloor heating system to maintain a safe and consistent flow temperature.
Why is a blending valve needed for underfloor heating?
Underfloor heating typically operates at much lower temperatures than radiators. A blending valve ensures the water entering the floor circuits is not too hot, helping protect floor finishes and improve comfort.
Is this valve suitable for heat pumps?
Yes. The Reliance Heatguard blending valve is suitable for many systems using air source and ground source heat pumps. Always ensure the overall system design and operating temperatures are appropriate for your installation.
Can I use this valve with a boiler?
Yes. It is commonly installed on wet underfloor heating systems connected to gas, oil or LPG boilers where water temperatures need to be reduced before entering the manifold.
What pipe size does this valve use?
The valve features standard 22mm compression connections, making it suitable for many domestic and commercial underfloor heating installations.
Can the outlet temperature be adjusted?
Yes. The thermostatic blending valve allows the outlet temperature to be adjusted within the manufacturer’s specified operating range to suit the requirements of your underfloor heating system.
Where is the blending valve installed?
The blending valve is normally installed as part of the underfloor heating manifold assembly, where it regulates the temperature of the water supplied to the heating circuits.
Is this suitable for replacing an existing blending valve?
Yes, provided the connection size, installation layout and operating requirements match your existing system. Always check compatibility before installation.
