4. What is the thermostatic mixing valve?

A Thermostatic Mixing Valve is a valve that blends hot water (stored at temperatures high enough to kill bacteria) with cold water to ensure constant, safe outlet temperatures preventing scalding.

They shut-off rapidly in the event of a hot or cold supply failure to prevent scalding or thermal shock.

TMVs accurately control water temperatures for bathing, showering and hand-washing. They maintain pre-set temperatures - even if water pressure varies when other appliances are used. TMVs can be fitted under baths and basins, be part of shower fittings, or as a feature of exposed hot and cold water mixers.

5. Usage of TMVs

Point of use mixing for wash hand basins, bidets, baths and showers in hospitals, schools, sport and leisure facilities, prisons and other public buildings.
