Safety Standards for Hot Water Storage Temperature

The Australian Safety Standard requires keeping hot water storage systems at a temperature of at least 60°C to avoid the growth of bacteria that may pose risks to human health. Water at 60°Cs causes a painful burning sensation if touched for five seconds.

The best way to prevent such burns is to reduce the temperature of your hot water supply to about 50°C. You can fit a tempering or mixing valve into your hot water system. These valves automatically lower the temperature of the water before it reaches the taps. They also allow you to control how much cold water goes into the mix.

Early childhood centres, schools, nursing homes, and similar facilities with an average hot water delivery temperature of 45ºC are exempt from these guidelines.

What is a hot water system?

Essentially, a hot water system (HWS) consists of a tank with an installed pump that circulates the hot water around the house. This means that every time you use a tap in your home, like your shower, kettle etc., the system pumps cold water from the mains through the pipes to heat up the water in the tank until it reaches the required temperature. Once it has reached its set point, the water flows back through the pipes to fill your taps.

There are different types of systems such as gas hot water systems, solar hot water systems, and electric hot water systems. Each of these types has different running costs and can be energy efficient. The only thing they are equal is when it comes to water heating. Because of their continuous flow system, there would be a continuous flow of hot water supply.
