8 Common Tankless Water Heater Issues
Let’s dive into the eight most common issues that can arise with tankless water heaters. By familiarizing yourself with these problems and their signs, you’ll be better equipped to identify and address any potential complications.
Insufficient Hot Water
- Signs – If you notice a decrease in the hot water supply or experience lukewarm water, it may indicate an issue with your tankless water heater.
- Possible Causes – Inadequate unit size, mineral buildup in the heat exchanger, or a malfunctioning temperature sensor can contribute to insufficient hot water.
Fluctuating Water Temperature
- Signs – Random bursts of hot or cold water during usage can indicate a fluctuating water temperature issue.
- Possible Causes – Sediment accumulation, a faulty mixing valve, inadequate water flow, or an incorrect temperature setting can cause erratic water temperature from your tankless water heater.
No Hot Water
- Signs – Complete absence of hot water when needed clearly indicates a problem with your tankless water heater.
