Thermostatic mixing valves mix the hot and cold water supplies to produce mixed water at a controlled temperature. The hot water supply from the heater is typically approximately 60°C. and is maintained at this temperature for a number of reasons:

  • to prevent the growth of potentially harmful organisms in the water system, in particular the Legionnella bacteria, which can cause Legionnaires disease.
  • to provide water at a suitable temperature to the kitchen and laundry
  • to provide a greater capacity of warm water to the building (by mixing with larger volumes of cold water)

However, exposure to water above 60°C can scald, with potentially lethal consequences. Therefore hot water should be mixed with cold water at the point of use (e.g. basin, bath, shower or bidet) to provide warm water at safely controlled and comfortable temperatures.
