Pressure Relief Valve

It’s worth noting that not all hot water systems require a hot water tempering valve. For example, tankless continuous flow models do not require one. This is because you are not storing water in a hot water tank. And you’ll likely not need one if your electric or gas hot water system already has a thermostatic mixing valve installed. But more on them later.

Moreover, an observable decrease in water pressure could result from a defective tempering valve. The valve could restrict the flow of hot water to a particular outlet, such as the outlet of a shower or a tap.

These often-overlooked pieces of hardware each serve a vital role in the installation of a hot water storage system to ensure you and your family are safe from burns every time you turn on the hot water tap.

A pressure reduction valve can be a valuable addition to many piping systems. If the incoming water pressure is too high, this can put unnecessary strain on water heaters, pipe work, plumbing joints, taps and tap washers. It can increase the risk of burst hoses on washing machines, water leaks and possibly magnify any existing water hammer problems. The AVG pressure reduction valves (PRV) are factory set at 500 kPa. The downstream pressure is adjustable from 250 to 650 kPa. For pressure monitoring, there is a gauge port on the body of the valve so that a gauge can be fitted to monitor the upstream and downstream pressure. Sizes DN15, DN20 and DN25.

Unfortunately, Saxon no longer produces heating units, but Metropolitan can still service, repair or replace your old Saxon system.

But why do you need a tempering valve in the first place? Water is stored at 60°C in a storage tank to prevent the growth of dangerous bacteria such as Legionella. However, if hot water was delivered at that temperature it would cause third-degree burns any time you ran the hot water tap. That’s why a tempering valve is used to reduce the hot water to about 50°C.

Thermostatic valves offer more precise control than tempering valves. They adjust the mix of cold and hot water in real-time to maintain a constant temperature. It makes them ideal for fluctuating water supply conditions. Tempering valves, on the other hand, blend heated water from your hot water system with cold at a fixed ratio, set to a safe temperature, usually around 50 degrees Celsius. Both types comply with Australian standards. However, your choice depends on your specific needs: whether it’s precision or consistent safety you’re after.

Vulcan hot water systems are forged tough so that they can handle Australia's changeable climate without missing a beat.

The key part of the valve is a temperature-sensitive element. This element expands or contracts based on the water temperature, influencing the water mix. Therefore, the thermostatic system keeps the balance of hot and cold water, delivering a stable outlet temperature.

Knowing the differences between thermostatic and tempering valves can be useful, whether you’re a plumbing enthusiast, or just want to understand your home better.

A thermostatic system mainly operates based on a thermostatic mixing valve (TMV). It blends hot and cold water to secure a consistent, safe outlet temperature, serving as a top-notch safety feature to prevent scalding.

Unlike tempering valves, they can respond instantly to changes in water flow or temperature. This guarantees a consistent and safe water temperature at all times. This makes them especially valuable in settings where precise temperature control is critical. These include homes with vulnerable residents or healthcare facilities with large capacity systems. These valves help to prevent scalding. They also help in controlling the growth of harmful bacteria like Legionella in your water system.

If you’re installing replacement hot water systems or a new hot water system as part of a new home build, it is mandatory to have a tempering valve installed in any bathroom.

A tempering valve is a key component in Australian home hot water systems. It plays a pivotal role in ensuring your hot water is safe. Also known as a hot water mixing valve or a mixing tool, they cleverly mix hot water from your hot water system with cold water. It effectively reduces the temperature to a safer level before it reaches your tap. You will have a tempering valve installed to make sure no scalding hot water could harm users.
