Underfloor Heating Mixing Valves
An underfloor heating system performs best when warm water reaches the floor at the correct temperature. Underfloor Heating Mixing Valves regulate the water flowing into your heating circuits, helping protect your flooring while maintaining comfortable room temperatures.
Whether your system connects to a traditional boiler or a renewable heat source, a quality mixing valve provides accurate temperature control and helps improve overall heating efficiency. By blending hot water from the heat source with cooler return water, the valve delivers the ideal flow temperature for wet underfloor heating.
At Kudos Trading, we stock high-quality mixing valves suitable for domestic and commercial installations, giving installers and homeowners reliable solutions for every project.
Why Use a Mixing Valve?
Underfloor heating operates at much lower temperatures than traditional radiator systems. While radiators may require water temperatures of 70–80°C, most underfloor heating systems perform efficiently between 35°C and 50°C.
A thermostatic mixing valve automatically adjusts the water temperature before it enters the manifold. As a result, it protects your flooring, improves comfort and helps your heating system operate more efficiently.
Key Benefits
- Accurate flow temperature control
- Protects floor finishes
- Improves energy efficiency
- Helps reduce overheating
- Compatible with boilers
- Suitable for heat pumps
- Reliable thermostatic operation
- Easy installation

- Professional-quality performance
Suitable for Modern Heating Systems
Our mixing valves integrate with a wide variety of heating systems.
Suitable applications include:
- Gas boilers
- Oil boilers
- LPG boilers
- Air source heat pumps
- Ground source heat pumps
- Hybrid heating systems
Selecting the correct valve helps maintain stable water temperatures and improves system performance throughout the year.
Thermostatic Temperature Control
Unlike manual valves, thermostatic mixing valves respond automatically to changes in water temperature.
As hot water enters the valve, the thermostatic element adjusts the amount of hot and cool water passing through the valve. Consequently, your underfloor heating system receives a consistent flow temperature without constant adjustment.
This automatic control improves comfort while protecting sensitive floor coverings from excessive heat.
Compatible with Underfloor Heating Manifolds
Our mixing valves work alongside many of the UK’s leading underfloor heating manifolds.
Compatible products include:
- Stainless Steel Manifolds
- Nickel Plated Brass Manifolds
- Reliance RWC Stainless Steel Manifolds
- Underfloor Heating Pump Packs
- Thermal Actuators
- Heatmiser Controls
Using compatible components helps create a reliable heating system that performs efficiently for many years.
How to Choose the Right Mixing Valve
Choosing the correct valve depends on your heating system.
Consider:
Heat Source
Boilers and heat pumps often require different system configurations.
Heating Area
Larger systems may require higher flow rates.
Manifold Compatibility
Always choose a valve that matches your manifold and pump pack.
If you’re unsure which valve suits your installation, our technical team can recommend the best solution.
Complete Your Underfloor Heating System
A mixing valve forms just one part of an efficient wet underfloor heating system. Pair it with compatible products to create a complete installation.
Underfloor Heating Manifolds
Choose from Stainless Steel, Nickel Plated Brass or Reliance RWC Stainless Steel Manifolds to suit your project.
Manifold Pump Packs
Many installations combine a mixing valve with a pump pack to regulate both water temperature and circulation.
Thermal Actuators
Add thermal actuators to automate each heating zone and improve room-by-room comfort.
Heatmiser Smart Controls
Control your heating system with Heatmiser NeoStat V3, NeoAir V3 and NeoHub Gen 3 for intelligent scheduling and remote control.
Underfloor Heating Pipe
Choose premium MLCP, PE-RT or PEX pipe for dependable long-term performance.

Frequently Asked Questions
What does an underfloor heating mixing valve do?
A mixing valve blends hot water from your heat source with cooler return water to deliver the correct flow temperature to your underfloor heating system.
Why do I need a mixing valve?
Most underfloor heating systems operate at lower temperatures than radiator systems. A mixing valve prevents excessively hot water from reaching your floor.
Can I use a mixing valve with a heat pump?
Yes. Many mixing valves work with both air source and ground source heat pumps, although some low-temperature systems may not require one depending on the design.
What temperature should underfloor heating run at?
Most wet underfloor heating systems operate between 35°C and 50°C, depending on the floor construction and heat source.
Does a mixing valve replace a pump pack?
No. A mixing valve controls water temperature, while a pump pack provides circulation. Many systems use both together.
Are thermostatic mixing valves automatic?
Yes. They adjust automatically to maintain a consistent water temperature without manual intervention.
Can I replace an old mixing valve?
Yes. Replacing a worn or faulty valve can improve temperature control and system efficiency.
Will a mixing valve improve efficiency?
Maintaining the correct flow temperature helps your underfloor heating system operate more efficiently while improving comfort.
Which manifold works with these valves?
Our mixing valves work with many leading manifold brands, including stainless steel, nickel plated brass and Reliance RWC manifolds.
Can Kudos Trading help me choose the correct valve?
Absolutely. Our technical specialists can recommend the correct mixing valve based on your heat source, manifold and heating system.
