Cleaning a tankless water heater is essential for its optimal performance and longevity. Follow these simple steps to ensure a clean and efficient unit. First, turn off the power supply to the heater by either flipping the breaker switch or unplugging it. Allow the water to cool down for at least 30 minutes before proceeding.
Next, locate the cold water inlet valve and shut it off to prevent any water from flowing into the heater during the cleaning process. Once the water supply is shut off, find the purge port valve and attach a hose to it. Run the hose into a drain or bucket to collect any debris and mineral buildup that will be flushed out. Gradually open the purge port valve to initiate the water flow.
After letting the water flow through the heater for about 10 minutes, close the purge port valve and disconnect the hose. Reopen the cold water inlet valve to restore the water supply to the heater. Check for any leaks or drips around the connections and fix them if necessary. Finally, turn on the power supply and wait for the heater to reach its regular operating temperature.
Regularly cleaning your tankless water heater ensures that it runs smoothly and efficiently, providing you with a steady supply of hot water whenever you need it.
