Yes. Manufacturer guidance typically recommends annual flushing, and skipping it can lead to reduced performance and avoidable breakdowns.
Some homeowners choose a DIY approach using vinegar and online tutorials. While this can be done to an extent, professional service ensures the unit is fully flushed, filters are cleaned, and the system is inspected for corrosion or leaks that are easy to miss.
Most appointments take about one hour.
Yes. Flushing and descaling are recommended on a routine schedule, not only when buildup is visible.
You typically have some flexibility, but performance can decline the longer maintenance is delayed. In homes with hard water, it is best to service the system once per year to prevent mineral buildup. If you have a water softener or whole-home filtration system, you may have a little more flexibility, but annual maintenance is still recommended for optimal performance and warranty protection.
Why Tankless Maintenance Matters
A tankless unit heats water through internal coils. Over time, mineral buildup and sediment can collect on those heating components. When that happens, the system cannot operate at optimal performance.
In our area, hard water and mineral buildup are common. This is especially true for homes on well water, since well water is often very hard. Even municipal water can cause issues. For example, Cobb County homeowners already see water quality-related concerns, such as pinhole leaks, and the same water quality can affect tankless system performance.
Just as important, if you ever have a problem with your tankless unit and troubleshooting is needed, one of the first questions the manufacturer will ask is when the unit was last serviced and flushed. Staying on schedule helps avoid delays and protects your investment.

How Often Should You Flush A Tankless Water Heater
Most manufacturers recommend flushing your tankless water heater once per year.
If you have very good water quality and use a water softener, you may be able to flush every two years. However, annual service is the safest recommendation for most homes in our area, especially given the common hard-water conditions.
If you go a little past the one-year mark, that is usually okay. The longer you go, the more likely performance drops and buildup increases.
Signs Your Tankless Water Heater May Be Overdue For Maintenance
If you notice any of the symptoms below, it is a good time to schedule service.
Common signs include
- Drop in water pressure
- Lukewarm water or inconsistent hot water

Standard Tank Water Heater Maintenance
Tank water heater flushing is recommended by manufacturers, but most homeowners do not keep up with it. If it is done, it may help extend lifespan depending on water quality, but the impact varies, and it is hard to predict how much extra life it adds.
Tankless systems are different. With tankless, routine flushing is crucial and directly impacts performance.
