Tankless Water Heater Maintenance: Why it Needs to Be Cleaned and Flushed

You’ve invested in a tankless water heater. Congratulations!


Tankless water heaters are much more efficient than their tank counterparts. This means that, although they are more expensive up front, they can save you money in the long run on utility bills.


One of the most common questions people ask about their tankless water heater is “how often should I flush it?”


Our latest blog explores tankless water heater maintenance and why cleaning it and flushing it regularly is beneficial to you.


Benefits of Flushing Your Tankless Water Heater

Reduce Sediment Buildup

The main reason to perform tankless water heater maintenance tasks like flushing is to remove sediment buildup. Water flows through your tankless heater and leaves behind small traces of minerals and sediment. Over time, these deposits start to buildup within your unit and begin to have a negative effect on the water flow and heat exchanger. This is especially true for areas with hard water.


Improve Efficiency

Removing all that built-up sediment will help to improve the efficiency of your unit. At optimal efficiency, your tankless water heater will use less energy to quickly heat water. This can lead to a lower energy bill as well.


Reduce the Risk of Malfunctions

Regular tankless water heater maintenance can mean your chances of malfunctions and breakdowns are drastically reduced. Regular maintenance can mean you catch small issues before they blossom into much larger and more costly repairs.


This also has the added benefit of extending your unit’s lifespan, meaning you don’t need to spend money on a replacement as often.


How Often Should You Clean and Flush It?

Regular maintenance means your tankless water heater can run as long as possible and be as efficient as possible.


Similar to a tank unit, it is recommended that you clean and flush your tankless water heater once per year. However, if you live in an area with harder water, you should consider flushing and cleaning your water heater more often – as frequently as every six months.


Other Tankless Water Heater Maintenance Tasks

Some tankless water heaters will have a sediment screen or filter to keep larger debris from entering the unit. They are usually usable for the life of your tankless water heater and can be easily cleaned under running water or soaked in white vinegar until free of debris.


For gas models, you should check and maintain the ventilation system. This helps ensure safe and efficient operation, plus it prevents dangerous buildups of carbon monoxide.
