Hot water is one of the most essential components in any household. Without the continuous supply of hot water, it becomes impossible to function properly. Whether it be cooking, showering, or cleaning, you need hot water for everything. However, we often take it for granted and forget its importance. In order to ensure the safety of your family, the tempering valve plays a critical role. Are you wondering what is a tempering valve?

What is a Tempering Valve?

Before you understand anything else, you must know what is a tempering valve. It is responsible for the mixing of the cold water with the hot water at the temperature of your choice. Then, it is going to showers, sinks, etc. This way, you can get comfortably warm water and prevent scalding.

How Does a Tempering Valve Work?

If you are wondering what does a tempering valve does, it actually mixes the cold and hot water to produce a safe water temperature. As per the Australian Standard AS3500.4.2 Clause 1.6., the water temperature must not be more than 50 c. However, in order to combat the development of legionella bacteria within the tank, the temperature must be at 60 c.

Well, it allows the water inside the tank to remain at 60 c, but when it flows out, it mixes with the cold water to get the temperature of your desire.

What Does a Tempering Valve Look Like?

Are you curious about what does a tempering valve looks like? There are two inlets – hot and cold on either side of the valve. Underneath, the mixed outlet is present, and on the top, you will find the temperature adjustment.

Location of the tempering valves

You can see the tempering valve on the external body of the hot water system. It is usually installed between the hot water and cold water line. It is because the cold water enters via the cold water inlet and then flows to the tempering valve. After that, it blends with the hot water, and the tempered water is then released everywhere in the house.

Types of tempering valves

Simply knowing what is a tempering valve is not enough. You must also know about its types. There are distinctly four types of tempering valves. These include –
