How to Tell if Your Tankless Water Heater Needs Repair

If you own a tankless water heater, you know how convenient it is to have instant hot water on demand. However, like all appliances, tankless water heaters can experience issues that can lead to repairs. It’s important to know the signs of a tankless water heater that needs repair so that you can address the issue quickly and prevent further damage or even a breakdown. Here are some signs that your tankless water heater may need repair.

No Hot Water:

One of the most obvious signs that your tankless water heater needs repair is no hot water. If you turn on the faucet and there is no hot water, then there may be an issue with the heating element or gas line of your tankless water heater. Try resetting the unit or checking for a gas leak, but if the issue persists, you may need to call a professional to repair or replace the unit.

Water Temperature Fluctuations:

If the water temperature of your tankless water heater keeps fluctuating, it could be due to several reasons, including a dirty air filter or a malfunctioning heating element. These issues can cause the temperature sensors on the unit to misread the water temperature, leading to inconsistent hot water. It’s essential to get this checked out by a professional as this issue can lead to damage to the unit over time.

Unusual Noises:

Your tankless water heater should be relatively quiet when it’s operating. However, if you start to notice humming or rattling noises, it could be due to mineral buildup within the unit. Mineral buildup can cause the heating element to work harder, leading to more energy consumption and eventually causing the unit to fail.

Rusty Water:

If you notice rusty water coming out of your faucet, it could be due to a rusted heat exchanger inside your tankless water heater. A rusted heat exchanger not only affects the quality of your water but also affects the efficiency of your tankless water heater. It’s best to have it replaced as soon as possible to prevent further damage.

Error Codes:

One modern convenience of owning a tankless water heater is the ability to see error codes on the unit. These codes can indicate when something is wrong with the unit and require attention from a professional. Be sure to check your unit regularly for any error codes and address them immediately.

While tankless water heaters are a convenient and efficient way to get hot water, they can experience issues that may require repairs. Knowing the signs that your tankless water heater needs repair can prevent further damage to the unit and ensure that you always have hot water on demand. If you notice any of the signs mentioned above, don’t hesitate to call a professional to address the issue.
