Thermostatic Mixing valves
Thermostatic Mixing valves
We have two types of systems in general in our domestic and commercial bathrooms or washing facilities:
- Warm or Tempered Water System
- Hot Water
Warm water or tempered water system which is water that is used for hygiene washing purposes e.g taking a shower, washing your hands, having a bath etc.
The temperature at the outlet ranges from 40 – 50 degrees Celsius
Depending on different factors such as
For the young and old, temperatures should not be over 45* C
This would include:
- Aged Care Facilities
- Primary and secondary Schools
- Hospitals
- Disabled wash areas
Everybody else 50*C is the maximum permitted temperature
It is an Australian requirement that all hot water systems be heated to 65* C to eliminate the growth of a bacteria called legionnaires disease which can be deadly.
This is where a TMV or thermostatic mixing valve comes into play
Hot and cold water entering the valve is mixed to a temperature set by the licensed plumber based on the factors listed above.
A thermally sensitive mechanism inside the valve automatically adjusts to allow for the required temperature setting,
simply by mixing hot and cold water it also provides a fail safe and can accommodate in variations and fluctuations in the supplied water.
TMVs are required to be serviced at least once a year by a licensed plumber with a TMV endorsement.
