Hot Water Safety

Hot Water Safety Checklist

Hot water systems must follow stringent protocols to be considered safe for use.

One of the most critical steps to follow in regards to your hot water system installation is to ensure it is undertaken by a professional. They should be appropriately licensed, otherwise you run the risk of inadequate installations that may skip over essential safety standards.

Hot water in the home can be a hazard if the temperature is too high. Water that is too hot can cause serious burn injuries, especially in the bath and shower.

Protecting Your Children From Hot Water

Hot tap water scalds

Contact with hot liquid or steam is the most common cause of a burn or scald. The bathroom is the most common place for hot tap water scalds.

At 50°C hot water takes 5 minutes to cause a full thickness burn, at 60°C it takes less than a second!

Safety with hot tap water:

  • Use a hot water tempering device to control the temperature of your tap water to a maximum of 50°C. A licensed plumber can install this for you.
  • Always test the bath water temperature before bathing your child. The maximum recommended temperature for bathing your child is 38°C
  • Child resistant taps/tap covers can help to stop your child from turning on taps.
  • Always run the cold water first and last when filling up a bath and never leave a hot running bath unattended.

It is now law in Western Australia (National Plumbing and Drainage Code AS 3500.4 2003) that the delivery of hot water be controlled for all sanitary fixtures like baths, basins and showers.

Hot water temperature should not exceed:

  • 45°C for early childhood centres, primary and secondary schools and nursing homes or similar facilities for young, aged, sick or disabled persons.
  • 50°C in all other buildings.

Compliance with these temperatures is optional for kitchen sinks and laundry tubs.
