In Australia, government regulations set specific standards for hot water systems to ensure both safety and efficiency:
Scalding from hot water can occur in just seconds, especially at higher temperatures. For instance, water at 60°C can cause third-degree burns in under five seconds. By law, new installations of hot water systems must include a tempering valve. This device mixes hot and cold water to ensure the temperature at your tap never exceeds the safe limit of 50°C. Do you have a tempering valve in your home?
While 50°C is the ideal temperature for taps, your hot water storage must remain at 60°C or higher. This is because bacteria like Legionella can thrive in lukewarm water, particularly in storage tanks or pipes where water can sit for extended periods. By keeping your storage temperature at 60°C or above, you reduce the risk of bacterial growth and safeguard your family’s health. Some other bacterias that could lurk are Pseudomonas, Mycobaterium avium, E. Coli, Aeromonas or Klebsiella Pneumoniae.
It is a balance for your hot water system. While you want to ensure water is hot enough to prevent bacterial growth, unnecessarily high temperatures can increase your energy consumption. Upgrading to a more energy-efficient water heater or installing a thermostatic mixing valve can also help keep your energy costs down while ensuring your family stays safe.
