Efficient, Accurate Temperature Control for Underfloor Heating Systems
Upgrade your underfloor heating system with the Reliance Thermoguard Mixing Valve Unit, a high-performance solution designed to deliver consistent, energy-efficient temperature regulation. Built as a direct replacement for the discontinued Thermomix model, the Thermoguard offers enhanced reliability, improved versatility, and a compact design tailored for modern installations.
With 3/4" female flow and return connections, this valve is compatible with a wide range of plumbing configurations, making it a practical choice for both new installations and system upgrades.
Why Choose the Thermoguard?
Consistent Temperature Stability: Designed for precision, the Thermoguard maintains accurate temperature control—even when mixed and return temperatures are similar—ensuring a comfortable and efficient heating experience.
Adaptable Installation: Whether you're installing left or right, this unit easily integrates into your system. Its flexible design supports both orientations on the manifold, allowing you to work with your existing layout.
Low-Temperature Operation: With functionality down to 25°C, this valve supports system warm-up and commissioning from low temperatures, protecting floor finishes and ensuring a safe, gradual heat-up process.
Space-Saving Design: The Thermoguard’s slim profile makes it easy to fit inside cabinets or confined spaces, keeping your installation neat and unobtrusive.
Wide Operating Range: Capable of blending temperatures from 25°C to 60°C, this unit accommodates various flooring types and heating demands with ease.
