First things first — what is a tempering valve?

A hot water tempering valve is a plumbing device designed to mix hot and cold water to a safe, pre-set temperature before it reaches your taps. This essential safety device ensures that water dispensed from your showers, baths and sinks is consistently at a temperature that won’t cause scalding injuries. Given the potential severity of hot water burns, especially for children and the elderly, tempering valves are essential in every household’s plumbing system.

How does a tempering valve work?

As mentioned, a tempering valve functions by blending hot water (stored at temperatures high enough to kill bacteria) with cold water to achieve a specific, safe output temperature. This process involves a thermostatic element within the valve that adjusts the mix based on the incoming water temperatures, ensuring consistent output even when there are fluctuations in water supply temperatures.

The importance of tempering valve hot water systems in plumbing

The primary purpose of a tempering valve is to prevent accidental scalding by limiting the maximum temperature of the water exiting your taps. Scalding can occur within seconds, particularly when water temperatures exceed 60°C. Installing a tempering valve mitigates this risk, ensuring the water remains at a safer, more manageable temperature, typically around 50°C for household use. This is particularly important in households with young children, elderly members, or individuals with sensory disabilities who might not quickly react to hot water.

Other benefits of installing a tempering valve

  • Compliance with regulations — To ensure public safety, installing tempering valves is often required in new constructions and major renovations.
  • Energy efficiency — By optimising the temperature of your hot water use, you’re likely to see a reduction in your energy bills. There’s less need to heat water to extreme temperatures, leading to savings over time.
  • Peace of mind — Knowing that your household is protected from the potential dangers of hot water allows you to enjoy your home comforts with an added layer of security.
  • Consistent water temperature — Tempering valves supply water at a consistent and comfortable temperature that’s ideal for bathing and washing.

Common issues with tempering valves

As with any device, tempering valves can experience wear and tear. 

Common issues include:

  • Clogging — Sediment from the water supply can build up, affecting functionality.
  • Thermostatic element failure — The element responsible for regulating temperature can wear out over time.
  • Adjustment issues — Incorrect installation or calibration can result in water temperatures being too hot or too cold.

Regular maintenance and checks by a professional plumbing service can help identify and rectify these issues promptly.
