It’s so important to make sure that your hot water unit is set to the correct temperature.

A child can be severely scalded in as little as a second, when the water temperature is around 65°C, a temperature not uncommon in some Australian homes.

Our regulations state that the hot water service temperature must not exceed 50°C at outlets that are used for bathing.  The recommended temperature setting for very young children is 37°C – 38°C.

To prevent bacteria growth, particularly legionnaires, hot water should be set at a minimum of 60°C in your hot water unit cylinder, and then regulated for your bathing outlets, through the tempering valve, to between 38°C – 50°C .

If you are in doubt about your hot water unit’s temperatures, don’t take any chances.  Give us a call and we can set things up safely for your peace of mind.



We can assist with all types of hot water heaters –  Rheem, Rinnai, Vulcan, Aquamax, Bosch & more.
