Usage of TMV’s

TMV’s are commonly found in installations such as aged care, nursing and retirement complexes, child care centers, hospital and medical facilities, disabled amenities buildings. Regular thermostatic mixing valve testing and maintenance ensures appropriate functioning of the system.

Function of TMV’s

The major role of thermostatic mixing valves is to mix a hot water supply (above 60°C) with the cold water supply to provide tempered water at predetermined temperature. The safe water temperature depends on the application and the facility the equipment is located in.

TMV performs another important function as well. If the cold water supply to the TMV is interrupted the valve will shut down the hot water supply to all fixtures downstream. It will protect anyone using hot water from potential burns, scalding or injury.

Types of facilities we service:

  • Hospitals and medical centres
  • Hairdressing and beauty salons
  • Disabled amenities / facilities
  • Childcare and early learning centres
  • Aged care and retirement facilities

Hot Water Scalds – The Facts

If you are late in calling professionals to service your TMV the result could be scalds or burns. The seriousness of scalds or burns depends on the temperature of the water and the time that contact was made with the hot water. A third-degree burn means the burn is through the full thickness of the skin and is likely to require surgery. There is a significant difference in the time taken to receive a third-degree burn at different temperatures.

Approximate contact times to receive a third-degree burn:

  • At 70°C – 1/sec adult – 0.5/sec child
  • At 60°C – 5/sec adult – 1/sec child
  • At 55°C – 30/sec adult – 7/sec child
  • Below 50°C – approx. 5 mins adult/child
