Tankless Water Heater in Las Cruces, TX

Troubleshooting Your Tankless Water Heater in Las Cruces, TX

November 19, 2021

Tankless water heaters are more effective than standard water heaters that use energy continuously to keep water in a tank hot. Instead of storing water in a tank, tankless water heaters provide hot water on demand. Here are several common issues homeowners in Las Cruces, TX experience with tankless water heaters and how to troubleshoot them.

1. Lack of Hot Water

Gas tankless units use burners and an electronic ignitor to generate heat and then transfer it to the unit’s flowing water as it heads to your tap. When the water heater doesn’t produce hot water, it could be that the burners have failed to ignite when you try to use the hot water.

There are multiple reasons why your tankless water heater may lack hot water, including electrical issues, gas flow issues, and dirt buildup tampering with the burners or heat exchangers. Inspect the circuit breaker for recurring electrical issues or call a professional to inspect your equipment immediately if you suspect any problems with the gas.

2. Mineral Buildup

A tankless water heater requires relatively little maintenance. However, these systems can experience problems like mineral buildup, which reduces efficiency and can eventually contribute to the system breaking down. If you are running hard water through your tankless water heater, you’d be wise to invest in a whole-home water softener installation.

3. Fluctuating Water Temperatures

If you experience temperature fluctuations in hot water from your tankless water heater, it may result from a variety of issues. These temperature fluctuations could be caused by a malfunctioning thermostat, damaged heating elements, or a failing thermocouple. Your best bet is to call a qualified service technician to diagnose the problem.

To help minimize the need for repairs, contact a professional for annual system maintenance visits. If you have a problem troubleshooting your tankless water heater, contact us at Dynamic Heating & Cooling, Refrigeration to schedule water heater and tankless services.
