Over time, a tankless water heater can build up minerals that can build up on and erode the walls inside the tank's heating chamber. To effectively maintain and clean the tankless water heater, you will need to get rid of and take out the mineral deposits from the tank at least once yearly. Continue on reading to learn how you can maintain your tankless water heater to ensure its optimal performance and efficiency.
Step 1: Turn off the power supply for your tankless water heater
This can be performed by shutting off the primary gas or shutting off the circuit breaker for electrical devices.
Step 2: Close and turn off the 3 water valves attached to your tankless water heater.
This procedure will prevent cold water from flowing into the water heater and stop hot water from emerging during the cleaning process.
The water valves consist of a cold water valve that might be colored blue, a hot water valve that may be colored red, and a third main valve that runs the water into your home.
Step 3: Remove the purge port valve caps carefully from the purge valves located on each of the cold and hot water valves.
The purge valves have small handles that mimic the letter "T"
This process is conducted to decrease any pressure that has built inside the valves and can prevent excess hot water from shooting out and coming into contact with your skin.
There could be pressure when taking out the purge port valve caps, so it is very essential to make sure the hot water valve is totally and accurately shut off for safety purposes.
Handle each cap carefully to make sure the runner washer sealing discs stay in place, which are needed for your valves to function correctly.
Step 4: Attach the hosing lines to all of the 3 valves.
If your manufacturer of the tankless water heater didn't supply you with hosing lines, you can purchase them from any local store specializing in home repair or water heaters. The hosing lines will have to be long enough to get between the water heater and your bucket.
You might need to consult your manual supplied by the tankless water heater's manufacturer or contact the manufacturer directly for precise instructions in regards to this process.
Sometime, this process may require you to use a sump pump and connect hoses that will discharge and flush water from the tankless water heater using the cold and hot water valves.
Step 5: Open the purge port valves by turning them perpendicularly to the position of the cold and hot valves.
Step 6: Use 2.5 gallons (9.46 liters) of undiluted white vinegar to clean the tankless water heater all the time rather than chemical solutions.
Since your tankless water heater is most likely the source of all your water supply and bathing water, using chemical cleaning solutions might be very harmful to your health.
Step 7: Complete the flushing and draining procedure by following the directions given by the maker of the tankless water heater.
This procedure can take up to 45 minutes.
Step 8: shut the purge port valves by twisiting the "T" shaped handles after the flushing process has been completed.
Step 9: Detach and take off the hosting lines from each water valve.
Step 10: Replace the purge port valve caps onto the purge valves.
Tighten the caps completely and securely without breaking the rubber sealing discs located inside the caps.
Step 11: Check with the manufacturer's handbook of your tankless water heater for exact directions on how to safely re-start your water heater unit.
This procedure can need you to rotate and open the cold and hot water valves so they are parallel to the position of the primary valve that leads into the house.
Step 12: Turn on the hot water tap in the sink slowly and gradually to let the air to pass through the pipe.
Continue to run the water till it runs steadily without air escaping.
This process may take up to 2 or 3 minutes.
