Required Tools and Materials for Cleaning
Before you begin the process of cleaning your tankless water heater, it is essential to gather all the necessary tools and materials. Having the right equipment will ensure a smooth and effective cleaning process. Here are the tools and materials you will need:
- Channel locks: These will be useful for opening stubborn parts of the water heater.
- Gallon of food-grade white vinegar: Vinegar is an excellent natural cleaning solution for removing mineral buildup and scale.
- Submersible sump pump: This pump will help push the vinegar through the water heater.
- Two hoses: You will need these hoses to connect the pump and the water heater.
- Bucket: A bucket will be used to hold the vinegar during the cleaning process.
- Optional gear - rubber gloves and old clothes: It's a good idea to protect yourself with gloves and wear old clothes to prevent any vinegar spills or splashes.
Gather all these tools and materials before you start cleaning your tankless water heater to ensure a hassle-free and efficient cleaning experience.
Now that we have covered the necessary tools and materials, let's move on to the next section to learn how to shut off the water heater before starting the cleaning process.
Shutting Off the Water Heater
To begin the step-by-step tankless water heater cleaning process, it is crucial to shut off the power source of the unit. If your water heater is gas-powered, turn off the gas line. For an electrical unit, switch off the circuit breaker. Additionally, close the three water valves attached to the water heater to prevent any water flow during the cleaning.
Step 1: Turn Off Power Source
For a gas-powered tankless water heater, shut off the gas line. Locate the gas supply valve and turn it clockwise to the "off" position. If your tankless water heater is electrical, find the circuit breaker that controls the unit and flip it to the "off" position.
Step 2: Close Water Valves
Locate the three water valves connected to your tankless water heater. There should be one valve on the cold water line, one on the hot water line, and one on the gas supply line (if applicable). Rotate each valve clockwise to close them tightly. This will prevent any water from entering the unit during the cleaning process.
By following these simple steps, you can safely shut off your tankless water heater and prepare it for the cleaning process. It is essential to ensure that the power source is disconnected and the water valves are closed to avoid any accidents or water damage.
Draining the Water Heater
Once you have shut off the water heater, the next step in the cleaning process is to drain the unit. This ensures that all the water inside is removed before proceeding with the cleaning. To drain the water heater, locate the drain caps on the hot and cold water lines. Remove these caps carefully. Now, it's time to drain the cold water line first. Turn on the small blue inlet valve next to the drain. This will allow the water to flow out of the cold water line. After draining the cold water line, it's time to drain the hot water line. To do this, turn on the small red drain valve. Be cautious while handling the water as it may be hot. It is recommended to wear gloves for added protection.
Draining the water heater helps to remove any sediment or debris that may have accumulated inside the unit. This step is crucial to ensure proper cleaning and optimal performance of your tankless water heater. By thoroughly draining the water, you can eliminate any potential blockages or buildup that could affect the efficiency and lifespan of the unit.
Before moving on to the next steps, make sure the water heater is completely drained. This will ensure that the subsequent cleaning and flushing processes are carried out effectively.

With the water heater drained, you are now ready to move on to the next step of the cleaning process: flushing the unit with vinegar. This will help remove any mineral buildup and scale that may have accumulated inside the water heater over time.
Flushing the Water Heater
Once the water heater is drained, it's time to flush it with vinegar. This step is crucial to remove mineral buildup and scale that can affect the performance of your tankless water heater. Flushing the water heater will help restore its efficiency and ensure a steady supply of hot water in your home.
To start, clean the prefilter located at the bottom of the unit. Unscrew it and remove any scale buildup. This will help improve the flow of water through the water heater. Next, attach hoses to the cold and hot drains, and connect the sump pump to the cold water hose. This setup will allow the vinegar to circulate through the water heater.
Fill a bucket with vinegar and turn on the sump pump. The vinegar will flow through the water heater, dissolving any mineral deposits and scale along the way. Let the vinegar run through the system for about an hour to ensure thorough cleaning. During this process, you may notice sediment or debris being flushed out of the water heater.

After an hour of flushing, remove the hoses from the valves and replace the drain caps. Turn on the water and gas lines to their previous positions. Be sure to discard the vinegar mixture into an appropriate drain or area. Finally, run hot water through a fixture in your house for a few minutes to completely flush out any remaining vinegar and debris.
Finishing Up the Cleaning Process
After an hour of flushing the tankless water heater with vinegar, it's time to finish up the cleaning process. Follow these final steps to ensure a thorough cleaning:
Step 1: Remove Hoses and Replace Drain Caps
Start by removing the hoses connected to the valves of the tankless water heater. Once the hoses are disconnected, replace the drain caps on the hot and cold water lines.
Step 2: Turn on Water and Gas
Next, turn on the water and gas lines to their previous positions. This will allow the water heater to resume normal operation. Make sure the valves are fully open to ensure proper water flow.
Step 3: Flush Out Remaining Vinegar
To completely flush out any remaining vinegar from the tankless water heater, run hot water through a fixture in your house for a few minutes. This will help remove any traces of vinegar and ensure clean, odor-free water.
By following this tankless water heater cleaning checklist, you can effectively clean your water heater and maintain its optimal performance. Remember to always consult the manufacturer's manual for specific instructions and guidelines. Regular cleaning and maintenance will help prolong the lifespan of your tankless water heater and ensure you have a reliable source of hot water in your home.
