Criterion HS109

# The temperature of warm water delivered from taps that children can access independently is not higher than 40°C, and comfortable for children at the centre to use.

Guidance

How to show you are complying

You must be able to show that the warm water flowing from taps accessed by children is comfortable and does not exceed 40°C.

We consider warm water between 25°C and 40°C to be a comfortable temperature. There are many ways to demonstrate compliance with this requirement. It largely depends on your context, including whether you use a hot water cylinder, continuous hot water, or a water heater.

Tempering valves and thermostatic mixing valves

If you use a hot water cylinder to store hot water, you could use a tempering valve to make sure the water temperature does not exceed 40°C.

A tempering valve is a safety device fitted by a plumber to provide water to taps at a consistently controlled temperature. It works by mixing hot and cold water between the hot water source and the outlet.

You could also use a thermostatic mixing valve to regulate water temperature. A thermostatic mixer will need to be installed by a plumber. It automatically blends hot and cold water to deliver water at a safe, consistent temperature of typically between 38°C and 50°C.

Continuous hot water systems

If you have a continuous flow gas hot water system, you could set the thermostat to deliver water between 37°C and 40°C for taps that children can access.

These systems are electronically controlled and can be installed with up to 3 temperature controllers for different water outlets. They are normally factory set to 55°C, so you will need to change the setting to 40°C or less.

When assessing whether you comply with HS109

Questions we are likely to ask

  • How do you make sure the temperature of water at children’s taps is less than 40°C?

We are likely to look at, measure or count

  • Use a thermometer to measure the temperature of the water flowing from different taps children access in your service to make sure it is comfortable and no hotter than 40°C.

We are likely to request

The hash symbol # indicates that we might ask for a report from the National Public Health Service, under Regulation 55 of the Education (Early Childhood Services) Regulations 2008. This report would help check if the temperature of water available to children is comfortable and no higher than 40°C.

It is important to control the temperature of water young children use because hot water can cause serious burns.

Doing more than the minimum can shape better outcomes for children. Here are some ideas or examples you might like to consider:

  • You may find it useful to keep a daily record of the temperature emanating from children’s taps, at full flow. Over time, this may help you determine that the technology supporting the taps is malfunctioning.

  • Before opening each day, you could check the temperature of the water flowing from these taps. You could keep a written or digital record of these checks.
