Common water heater problems.
One of the most common water heater problems we encounter is inconsistent water temperature. Typically, an unreliable hot water supply is a sign that your water heater needs repairing or servicing. Common issues may include:
- Water temperature is too hot or too cold, despite setting adjustments.
- Inconsistent water temperature and fluctuations between hot and cold water.
- Extended times for hot water to reach the tap.
What causes inconsistent hot water temperature?
Usually, it’s a faulty tempering valve.
Typically, hot water fluctuation problems are a sign of a faulty tempering valve. The hot water heater tempering valve (sometimes referred to as the temperature valve) mixes hot water with cold water to ensure a safe and consistent water temperature that is suitable for household use. It helps prevent hot water scalding by regulating the water temperature.
Without the tempering valve (temperature valve), the hot water produced by a water heater can be too high. To cool down the water temperature, the tempering valve mixes cold water with hot water to achieve a safe and comfortable temperature for safe household use.
A sensor in the tempering valve monitors the water temperature and a mixing valve then adjusts the ratio of hot and cold water to achieve the desired temperature.
The tempering valve is usually installed near the hot water heater or the plumbing between the water heater and the fixtures.
Along with preventing scalding, the tempering valve actually helps reduce energy consumption by allowing the hot water system to be set at a higher temperature whilst helping to extend the life of plumbing fixtures and reduce build up of sediment because it reduces the temperature differential between hot and cold water.
