Keep the hot water flowing. These five simple maintenance tips can help your tankless water heater last longer, run better, and avoid costly repairs.
One of the biggest advantages of a tankless water heater is simple: endless hot water when you need it. These systems are energy efficient, compact, and built to last—but like any hardworking appliance, they perform best with regular maintenance.
The good news? A little preventative care can help keep your tankless water heater running efficiently while reducing the chances of unexpected repairs.
1. Flush the System Regularly
Utah's hard water contains minerals like calcium and magnesium that can build up inside the heat exchanger over time. This scale buildup forces your water heater to work harder, reducing efficiency and potentially shortening its lifespan.
Most manufacturers recommend flushing or descaling a tankless water heater about once a year. Homes with especially hard water may benefit from more frequent service.
2. Clean the Water and Air Filters
Many homeowners don't realize that tankless units include small filters designed to keep debris out of the system.
Checking and cleaning these filters periodically helps maintain proper water flow and efficient operation. It's a quick maintenance task that can make a noticeable difference in performance.
3. Watch for Changes in Performance
Your water heater will often give you clues before a problem becomes serious.
If you notice fluctuating water temperatures, lower water pressure, unusual error codes, or longer wait times for hot water, it may be time for maintenance. Addressing small issues early can help prevent larger repairs later.
4. Schedule Professional Service When Needed
While some routine maintenance can be handled by homeowners, an annual inspection by a qualified technician can provide added peace of mind.
A professional can inspect connections, verify safe operation, clean internal components, and identify wear before it becomes a costly repair.
5. Protect Your Investment
A tankless water heater is designed to provide reliable hot water for many years, but longevity depends on proper care.
Routine maintenance not only helps improve efficiency and reduce energy use, but it can also extend the life of your system and support manufacturer warranty requirements.
Small Maintenance, Big Benefits
Homeownership comes with responsibilities, but many of the best maintenance tasks are also the simplest. Spending a little time caring for your tankless water heater today can help you enjoy dependable hot water, lower operating costs, and fewer surprises tomorrow.
