How Important is Your Tempering Valve?

A tempering valve plays a critical role in controlling the temperature of hot water delivered to your home, ensuring it doesn't reach dangerous levels that could cause burns or scalds. In several Australian states, it’s legally required for technicians to install a tempering valve when setting up a new hot water system.

Although these valves can be adjusted to higher temperatures, the standard in Australia is to keep them at or below 50° Celsius for safety.

The valve operates by mixing hot and cold water from your pipes, using a temperature monitor to ensure the water temperature remains safe. Inside the valve, a thermostatic element expands or contracts in response to temperature changes, controlling a piston that adjusts the flow of hot and cold water. This mechanism allows the valve to maintain a consistent temperature, typically within 3°C of the set point.

When your Upside Down plumbing specialist installs your hot water system, they’ll ensure the storage tank heats water to at least 60°C. Your plumbing professional will fit a tempering valve to reduce the water temperature to 50°C by mixing in cold water. This not only enhances safety but also reduces your overall hot water consumption.

Where is the Tempering Valve?

Tempering valves are generally installed close to the hot water system and can be positioned either vertically or horizontally, offering flexibility during installation.

However, specific regulations dictate the installation distance based on the type of water heater being used. In some cases, pressure-reducing valves might be necessary, and it’s common for tempering valves to require isolating valves on both the hot and cold water inlets for proper operation.

It's important to note that tempering valves aren’t needed for pre-set gas continuous flow hot water systems, as these are already calibrated to deliver water at 50°C.

For storage systems that heat water to higher temperatures, however, a tempering valve is essential. This is because storage tanks must heat water to at least 60°C to eliminate the risk of legionella bacteria, making the tempering valve critical for mixing in cold water to ensure the water delivered to taps is safe at 50°C.

Top-Notch HWS Maintenance from Upside Down

Only a fully licensed plumber, like the specialists at Upside Down, is qualified to install or replace a tempering valve. The precise calibration required to ensure the tempering valve is set to the correct temperature demands the expertise of a fully trained professional.

Beyond just installing the valve, our skilled plumbers will also conduct a thorough assessment of your entire hot water system.

This includes checking components like the pressure limiting valve, which is responsible for controlling the water pressure entering your system, ensuring it stays within the safe limit of 500 kPa (kilopascal). Properly maintaining these elements is crucial for the efficient and safe operation of your hot water system.

FAQ − Do You Have Questions About Tempering Valves?

If you’ve got any queries about tempering valves, we’ve got the answers below.

Your tempering valve typically has a lifespan of 5 to 8 years, but with regular inspections and maintenance, you can extend its longevity and catch issues before they become serious. Many problems with tempering valves are caused by debris build-up from your water heater. To prevent this, it's recommended to flush your water heater annually, which helps reduce sediment accumulation in both the tank and the tempering valve. Installing an inline filter is another effective measure, as it prevents debris from entering your hot water system in the first place. Additionally, older hot water systems are more susceptible to rust and sediment build-up, which can also impact the performance of your tempering valve. Regular maintenance is key to ensuring everything runs smoothly and prolonging the life of your system.

Tempering valves and the 50°C maximum water temperature standard were introduced in Australia to reduce the risk of scalds and burns from excessively hot water. As water temperature rises, the time it takes to cause a third-degree burn decreases significantly. The risk of burns varies with water temperature:
  • At 70°C, an adult can suffer a third-degree burn in just 1 second, while a child can be burned in 0.5 seconds.
  • At 60°C, it takes 5 seconds for an adult to get a third-degree burn and only 1 second for a child.
  • At 55°C, a third-degree burn can occur in 30 seconds for an adult and 7 seconds for a child.
  • When water is below 50°C, it takes about 5 minutes for a third-degree burn to develop for both adults and children.
Most tempering valves come equipped with a thermal shut-off feature, which automatically stops the flow of mixed water if there is an issue with the hot or cold water supplies. This safety mechanism ensures that no excessively hot water exits the valve, providing an additional layer of protection.

Thermostatic mixing valves (TMVs) function similarly to standard tempering valves by keeping water temperatures safe and below scalding levels. However, TMVs are designed with a faster response time to changes in pressure and temperature, making them more sensitive and reliable. Due to their enhanced precision, TMVs are required in settings such as schools, childcare centres and nursing homes, where water temperature is typically set at 45°C for added safety.
