A Quick Guide to Tankless Water Heater Maintenance

September 11, 2023

Your tankless water heater plays a crucial role in keeping your home comfortable by providing hot water whenever you need it. To ensure its optimal performance and longevity, regular maintenance is essential. By following these simple steps, you can keep your tankless water heater running smoothly and avoid costly repairs.

Check the Water Filter

Tankless water heaters have a built-in filter that prevents debris and minerals from entering the unit. Over time, this filter can become clogged, reducing efficiency. Check and clean the filter every few months, or as recommended by the manufacturer, to maintain water flow.

Flush the System

Mineral buildup can accumulate within the heating elements of your tankless water heater, affecting its efficiency. To prevent this, schedule a yearly flush of the system. This involves running vinegar or a descaling solution through the unit to dissolve mineral deposits.

Inspect for Leaks

Regularly inspect your tankless water heater and the surrounding area for any signs of leaks. Leaks can lead to water damage and decreased performance. If you notice any leaks, address them quickly by contacting a professional plumber.

Check for Proper Ventilation

Proper ventilation is important for tankless gas water heaters. Check that the exhaust vent is clear of obstructions and free from debris. Proper ventilation prevents the buildup of harmful gases and allows for safe operation.

Monitor Water Temperature

Check the temperature of the hot water coming from your tankless water heater. If you notice fluctuations or inconsistent temperature, it could indicate a problem with the unit’s heating elements or sensors. Consult the manufacturer’s manual or a professional if you encounter this issue.

Schedule Professional Maintenance

While some maintenance tasks can be handled by homeowners, it’s recommended to schedule a professional maintenance service annually. While it may seem like just one more expense, it’s something that can save you a ton of money and stress later down the line. A certified technician can perform a comprehensive inspection, identify potential issues, and verify that your tankless water heater is in optimal condition.

Follow Manufacturer’s Guidelines

Every tankless water heater model has specific maintenance recommendations from the manufacturer. Make sure to read and follow the user manual’s guidelines for maintenance to keep your unit in peak condition. This may seem like something you don’t “have” to do, but if you want to make the most of your tankless water heater, it’s something you certainly should do!

Keep Your Tankless Hot Water Heater in Tip-Top Shape

By dedicating a little time to regular maintenance, you can extend the life of your tankless water heater, so it continues to provide you with reliable hot water. If you’re unsure about any maintenance tasks or encounter issues, don’t hesitate to contact a professional plumber or follow the manufacturer’s recommendations. With proper care, your tankless water heater will serve you well for years to come, maintaining your home’s comfort and convenience.
