Troubleshooting Your Tankless Water Heater
Tankless water heaters are efficient and reliable alternatives to conventional storage tank models. However, like all HVAC systems, they can experience occasional breakdowns. Before calling for service, try troubleshooting these common issues:
Lack of Hot Water
If you’re not getting hot water, the burners might not be igniting properly. Possible causes include:
- Electrical issues
- Insufficient gas flow
- Damaged sensors
- Dirt or dust buildup
Check the circuit breaker and pilot light to determine if the problem is electrical or gas-related. If the water heater is tripping the circuit, it’s time to call a professional.
Fluctuating Water Temperatures
Inconsistent water temperature can be caused by:
- Incorrect thermostat settings
- Water pressure fluctuations due to plumbing issues
- Dirt, debris, or mineral buildup restricting water flow
- Leaks in your pipes
If adjusting the thermostat doesn’t solve the problem, inspect your plumbing for potential issues.
