Tankless water heaters are popular due to their energy efficiency and endless supply of hot water. However, over time, mineral deposits can build up inside the heater, diminishing its performance and potentially causing damage. Flushing a tankless water heater is a necessary maintenance task to keep it functioning properly. Wondering how to flush a tankless water heater? You’ve landed in the right place to get it done safely and efficiently.
Why You Need to Flush a Tankless Water Heater?
Flushing a tankless water heater helps remove mineral deposits that accumulate inside the unit. These deposits can reduce the flow rate of hot water and cause uneven heating. Flushing also helps prolong the lifespan of the heater by preventing corrosion and extending its overall efficiency.
Before Flushing a Tankless Water Heater
Before beginning the flushing process, make sure to turn off the power supply and the water supply. This can be done by switching off the circuit breaker or unplugging the unit.
Locate the shut-off valves on both the cold water inlet and hot water outlet pipes of the water heater. Close these valves to stop the flow of water into and out of the unit. From there, you’re ready to get started!
Steps to Follow
1) Connect Hoses – To flush the tankless water heater, you will need to connect hoses to the cold water inlet and hot water outlet valves. Use a pair of pliers to loosen the nuts on these valves and attach the hoses securely.
2) Submerge Hoses in a Bucket of Descaling Solution – Fill a bucket with a recommended descaling solution. This can be something like white vinegar, mixed with water. Make sure to fully submerge the hoses in the solution!
3) Open Valves and Let the Solution Circulate – Open both the cold water inlet and hot water outlet valves. This will allow the descaling solution to circulate through the tankless water heater. Let the solution run for at least 45 minutes to effectively dissolve the mineral buildup.
4) Rinse With Clean Water – After the recommended time has passed, close the valves and disconnect the hoses from the tankless water heater. Flush the unit thoroughly by running clean water through it to remove any remaining descaling solution.
5) Check for Debris and Signs of Damage – Inspect the internal components of the tankless water heater for any debris or signs of wear and tear. Clear out any accumulated debris and ensure all parts are in good condition.
6) Restore Power and Water Supply – Once everything is clean and in proper order, restore the power supply by turning on the circuit breaker or plugging the unit back in. Open the shut-off valves to allow water to flow into and out of the tankless water heater again.
How Often Should You Flush a Tankless Water Heater?
The frequency of flushing a tankless water heater depends on various factors, including the hardness of the water in your area and the manufacturer’s recommendations. In general, it is recommended to flush the unit at least once a year to maintain optimal performance. However, if you notice a significant decrease in hot water flow or experience issues with the heater, it may be necessary to flush it more frequently.
Other Recommended Maintenance
Now that you know about flushing tankless water heaters, let’s take a look at a few other areas. One of those is knowing the right size of tankless water heater that you need. It will depend on the size of your family and how much water they are using. You can do this by calculating the Flow Rate, gallons per minute or (GPM), and temperature pressure.
Another is fixing low water pressure. This can happen for several reasons, such as partially closed valves, debris in pipes, corroded water lines, and leaking water pipes to name a few.
Lastly, if your AC unit is near your water heater and it is leaking water, you may not know which unit is leaking. Take a closer look at the AC unit and it can be leaking because of a clogged drain line, dirty air filter, or low refrigerant.
When to Call a Professional
Flushing a tankless water heater can often be a DIY task. However, there are times when it’s wise to call in a professional. If you’re unsure about the steps involved, proper tools, or causing damage to your unit, get a pro.
They can also identify any underlying issues that may not be obvious to the untrained eye, potentially saving you from costly repairs down the line. Additionally, a professional can provide maintenance tips and answer any questions you might have about the care and operation of your tankless water heater.
