Four Signs That Indicate Your Tankless Heater Needs Repair


Reduced Hot Water Output

If you notice a decrease in the amount of hot water or if the water doesn't reach the desired temperature as quickly as it used to, it could signal a need for a tune-up. Mineral deposits or sediment buildup within the unit can affect its efficiency and hinder the heating process.

Fluctuating Water Temperatures

Inconsistent water temperatures, such as sudden changes from hot to cold during use, could indicate issues with the heating elements or sensors in your tankless water heater. A tune-up can help address these issues and restore consistent water temperatures.

Longer Wait Times for Hot Water

If there's a delay in getting hot water when you turn on the faucet, it might indicate an issue with the flow rate or heat exchanger in the tankless water heater. A tune-up can optimize these components for faster hot water delivery.

Unusual Noises

Unusual noises like banging, popping, or rattling coming from your tankless water heater could be a sign of mineral deposits or debris buildup. These deposits can affect the unit's performance and lead to inefficiencies. A tune-up can involve descaling and cleaning to address these issues.

Frequently Asked Questions About Tankless Water Heater Repair

We recommend having your tankless water heater professionally serviced at least once a year. In areas with hard water like Granger, IN, you may benefit from more frequent maintenance (every 6-9 months) to prevent mineral buildup. Regular tune-ups help maintain efficiency, extend the unit's lifespan, and prevent costly repairs.

Common issues include mineral buildup from hard water, ignition or flame failure, inconsistent water temperature, reduced hot water flow, error code displays, and sensor malfunctions. Many of these problems can be prevented with regular maintenance and descaling services from Cavinder Plumbing, Heating and Cooling.
