What’s Included in Tankless Water Heater Maintenance?

System Inspection

A thorough inspection checks every component of the unit for safety and performance. Technicians review wiring, gas or electrical connections, and venting systems, making sure all parts are functioning properly. This step helps catch small issues before they become costly problems and provides peace of mind that the system is safe.

Descaling and Flushing

Hard water causes mineral buildup that can strain the heat exchanger and lower efficiency. Professional descaling and flushing removes scale and sediment, restoring full performance and extending the life of the unit. Regular flushing is the best way to avoid energy waste and expensive repairs.

Filter Cleaning or Replacement

Air and water filters keep debris from entering the system. When they clog, the heater has to work harder and water quality can suffer. Cleaning or replacing filters during maintenance keeps the unit efficient and helps reduce wear and tear. Having a technician handle this step ensures nothing is overlooked.

Performance Testing

After service, technicians run a full performance test to confirm the heater produces consistent hot water at the right temperature and flow rate. Testing verifies that all maintenance steps are effective and ensures smooth, reliable operation.

Factors That Affect Maintenance Costs

Water Quality

Homes with hard water require more frequent descaling, while softer water can extend the time between services. Addressing water quality early can save money and protect the system from unnecessary strain.

System Usage

The more often hot water is used, the greater the demand on the heater. High-usage homes or businesses may need maintenance more frequently to prevent premature wear and keep water flowing reliably.

Age of the System

Older units often need more detailed inspections and occasional part replacements. Regular servicing helps identify worn components early, adding years to the life of the system.

Maintenance agreements provide scheduled care, discounted repairs, and priority service. These plans lower overall costs by avoiding emergency breakdowns and ensuring consistent attention to your water heater.
