What Temperature Should a Hot Water Heater Be Set At?

Hot water safety!

THE WORST KIND OF HOT WATER EMERGENCY IS A VISIT TO THE HOSPITAL.

Did you know thousands of Aussies are hospitalised every year due to scalding/ burns from unsafely tempered hot water heaters. It is of our opinion that over 60% of homes in Australia do not have a temperature control device (tempering valve). We believe hot water emergency room visits can be minimised with a simple device install called a tempering valve.

Enjoy hot water safely

All hot water systems are fitted with a thermostat. Please do not confuse a thermostat with a tempering valve. Most storage hot water systems store water at above 60°C. The thermostat will not allow the water temperature to drop below this temperature due to health risks. This was recognised by the Victorian government and a legislation was passed in 1998 aimed at eliminating the risk of Legionella bacteria. At 60°C it would take less then 5 sec to cause major burns.

See table below for approximate burns to time

49°C water takes 5min to cause major burns.

54°C water takes 30 sec to cause major burns.

60°C water takes 10 sec to cause major burns.

63°C water takes 3 sec to cause major burns.

Best way to prevent scalding

The best way to reduce scalding in your home is to temper down the delivery temperature out of the hot water system.

  • Never leave children or elderly unattended in bathrooms that have hot water exceeding 50°C
  • Check the hot water temperature repeatedly during the supervision of children in the shower.
  • Even quickly answering the front door can put your children at risk while they in the shower/bath
