A tankless water heater is one of the most valuable features in a modern home. It provides hot water on demand, uses less energy than traditional water heaters, and takes up less space. Like any major home system, however, it performs best when properly maintained.
If your home includes a tankless water heater, a few simple maintenance steps can help maximize efficiency, extend the lifespan of the unit, and ensure you always have reliable hot water.
Why Tankless Water Heater Maintenance Matters
Unlike traditional water heaters that store water in a tank, tankless systems heat water as it passes through the unit. Over time, minerals from hard water can build up inside the system, reducing efficiency and putting extra strain on the equipment.
Routine maintenance helps:
- Improve energy efficiency
- Extend the life of the unit
- Maintain consistent hot water performance
- Reduce the risk of costly repairs
- Protect manufacturer warranties
Flush the System Annually
One of the most important tankless water heater maintenance tasks is flushing the unit to remove mineral buildup.
In areas like Utah, hard water can create scale inside the heat exchanger. If left untreated, this buildup can reduce efficiency and shorten the life of the system.
Most manufacturers recommend having the unit professionally flushed once per year.
Check and Clean the Air Filter
Many tankless water heaters include an air intake filter that helps keep dust and debris out of the system.
Periodically inspect the filter and clean it according to the manufacturer’s recommendations. A clean filter helps the unit operate efficiently and prevents unnecessary strain on internal components.
Inspect the Exterior
Take a few minutes every few months to visually inspect the unit.
Look for:
- Water leaks
- Corrosion
- Loose connections
- Unusual noises during operation
Catching small issues early can help prevent larger repairs down the road.
Monitor Water Quality
Hard water is one of the biggest factors affecting tankless water heater performance.
If your area has hard water, consider installing a water softener or scale prevention system. This can significantly reduce mineral buildup and help your water heater operate more efficiently for years to come.
Schedule Professional Maintenance
While homeowners can perform basic inspections, an annual professional service is recommended.
A qualified technician can:
- Flush the system
- Inspect gas and water connections
- Check venting
- Test safety features
- Ensure the unit is operating properly
This small investment can help avoid unexpected issues and keep your system running smoothly.
