The Practical Guide for Homeowners: Maintenance Tips for Your Tankless Water Heater

Tankless water heaters are a great option for homeowners looking to save energy and enjoy on-demand hot water. But while they require less space and can last longer than conventional storage water heaters, they still need regular upkeep to run efficiently. RAM Plumbing, the go-to local plumber in Oro Valley, AZ, shares a simple guide to help you keep your tankless unit in good condition.

Flush the System Annually

Mineral buildup, especially in areas with hard water, can reduce your appliance’s efficiency over time. To prevent this, it’s recommended to flush your system once a year using a descaling solution or white vinegar. This process removes calcium and lime deposits from the heating elements and pipes. Some homeowners choose to do this themselves, but hiring professional plumbing services ensures the job is done thoroughly and safely.

Clean the Inlet Filter

The inlet filter protects your tankless unit from dirt and debris that can clog the system. Over time, this filter can become dirty and block water flow. Checking and cleaning the filter every few months helps keep water moving freely and protects the internal components of the heater. The process is usually quick—just turn off the water supply, remove the filter, rinse it under running water, and put it back in place.

Inspect the Venting System

Proper venting is critical for gas-powered tankless water heaters. Make sure the vents are free from dust, debris, or any blockages that could affect airflow. If the venting system is damaged or improperly installed, it can lead to dangerous carbon monoxide buildup. Regular visual checks are important, and if you ever notice odd smells or sounds, contact your local plumbing company right away.

Check for Error Codes

Many tankless water heaters display error codes when something isn’t working right. Familiarize yourself with your unit’s manual to understand what the different codes mean. This allows you to respond quickly to minor issues before they turn into major or emergency plumbing problems.
