A Tankless Water Heater can collect minerals overtime that can buildup on and wear away the walls inside your tank.
To properly preserve, maintain, and clean your Tankless Water Heater, at least once per year, you must flush and remove the mineral deposits from your tank.
You will want to make sure the tank is free from elements that are from lime scale buildup. If you let this buildup, overtime, it can lead to longer burn cycles, shorter tank lifespan, and a strained system that does not function properly. The work to maintain a Tankless Water Heater is simple to do and if you maintain it every year, then you will save time and money.
To maintain your Tankless Water Heater and ensure its optimal efficiency and performance, follow the 10 easy steps below.
What you will need to follow this tutorial:
- Knowledge of where the Tankless Water Heater is located in your home.
- Knowledge of where the circuit breaker for electrical devices is located within your home.
- 2.5 Gallons of “Undiluted White Vinegar”.
- Three Hoses long enough to reach the water heater and bucket
- Small Sump Pump
- Large Bucket (enough to hold two times the amount of white vinegar)
- Your Tankless Water Heater Manuel (Used for Restarting the Tankless Water Heater)
Step by Step Instructions:
- After you have located the Tankless Water Heater and the electrical circuit in your home, you will want to shut off the main gas line, or you can turn off the circuit for the electrical devices. This will turn off the power source for the Tankless Water Heater.
- You will now want to make sure the cold water is turned off on the Tankless Water Heater. There should be three valves attached to the Tankless Water Heater, they maybe red for hot water, blue for cold and another that could be yellow or not colored that runs the water from the line into your home. Start by turning off all three valves. This will stop the cold water from flowing into the hot water as well as stop the hot water from flowing out.
- Next, you will need to slowly remove the purge port valve caps. This will help relieve any extra pressure that may be left after you have turned the water valves off. Use caution at this point, and remove them slowly making sure the seal discs stay in place on the caps.
- Attach the three hoses to the three valves and let them fall into the bucket that has the vinegar and the pump. You can connect the two hoses to the sump pump that will discharge and flush the water from the hot and cold valves.
- Open the purge port valves by turning them upright towards the position of the hot and cold valves. They look like “T”’s and there is two of them located on the hot and cold valves.
- Follow your instructional manual on how to continue to flush the Tankless Water Heater. Not all tanks are the same but they have similarities. This point can take up to an hour to finish completely.
- Once flushing is finished, close the purge ports by turning the “T” handles and then disconnect the hoses carefully.
- Replace the purge port caps and ensure that all is tightened properly.
- Once you replace the filter, if your instruction manual says that you need to have a new one, turn on the hot water. Let the faucet in your sink run slowly to prevent any air pockets from occurring.
- Refer to you manufactured instruction manual for safety precautions and how to restart the Tankless Water Heater.
In conclusion, keeping your Tankless Water Heater is relatively simple to do. If all the steps above have been followed, correctly you will prevent a buildup that could be damaging to the tank. Make sure to do this at least once a year to increase the longevity of your Tankless Water Heater, and please make sure to use caution at all times. Therefore, what did you think about this tutorial?
