    Reliance Heatguard TMV3 Thermostatic Mixing Valve.

    Professional TMV3 Protection for High-Risk Hot Water Systems

    Maintaining safe hot water temperatures is essential in environments where vulnerable people are present. The Reliance Heatguard TMV3 Thermostatic Mixing Valve has been developed to deliver accurate temperature control while helping protect users from scalding in healthcare and commercial installations.

    Unlike standard domestic mixing valves, the Heatguard TMV3 is designed to meet the demanding performance requirements of TMV3 applications. It continuously blends hot and cold water to deliver a stable outlet temperature, even when system conditions fluctuate. If the cold water supply fails, the valve rapidly shuts off the hot water flow, providing an important fail-safe feature that helps prevent accidental scalding.

    Manufactured by Reliance Valves, the Heatguard TMV3 combines precision engineering with durable brass construction to deliver long-term reliability. Its compact design allows straightforward installation while providing easy access for commissioning and future maintenance.

    The valve is suitable for healthcare facilities, care homes, schools, hospitals, leisure centres and many other commercial properties where hot water safety is critical. It also offers excellent performance in specialist domestic installations where enhanced temperature control is required.

    Whether you’re specifying products for a healthcare project or replacing an existing TMV3 valve, the Reliance Heatguard TMV3 provides dependable safety, excellent reliability and compliance with recognised industry standards.

    FAQs

    What is a TMV3 thermostatic mixing valve?

    A TMV3 thermostatic mixing valve blends hot and cold water to provide a controlled outlet temperature. It is designed for healthcare and commercial environments where enhanced protection against scalding is required.


    What is the difference between TMV2 and TMV3?

    TMV2 valves are intended for domestic installations, while TMV3 valves meet stricter performance requirements for hospitals, care homes, schools and other higher-risk environments.


    Does the Reliance Heatguard TMV3 have a fail-safe function?

    Yes. If the cold water supply fails, the valve automatically shuts off the hot water flow to help prevent dangerously hot water from reaching the outlet.


    Where can I install a TMV3 valve?

    TMV3 valves are commonly installed in hospitals, care homes, schools, leisure centres and commercial washrooms where hot water safety is a key requirement.


    Why is TMV3 approval important?

    TMV3 approval demonstrates that the valve has been independently tested to meet recognised performance standards for high-risk healthcare and commercial applications.
