How to Clean Your Rheem Tankless Water Heater Efficiently

Regular maintenance is key to ensuring the longevity and efficiency of your Rheem tankless water heater. By cleaning your tankless water heater, you can prevent mineral buildup, which can significantly reduce its performance. In this guide, we will walk you through the step-by-step process of cleaning your Rheem tankless water heater, ensuring your water heater operates at its best.

Tools and Materials Needed

Before you start, gather the following tools and materials:

Bucket White vinegar or tankless heat exchanger flushing fluid Circulating pump Hose connections Mild detergent Cloth Litmus paper (for monitoring solution pH) PPE (Personal Protective Equipment)

Step-by-Step Cleaning Process

Step 1: Safety First

Begin by ensuring the safety of the operation. Turn off the power supply to the water heater and close the water valves to the system.

Step 2: Connectivity Setup

Connect a sump pump to the cold-water service port and a hose to the hot-water service port. Place both ends into a bucket filled with white vinegar. For more comprehensive cleaning, you can purchase tankless heat exchanger flushing fluid from a supply store. These kits include everything you need, such as a circulated pump, hoses, and directions.

Step 3: Circulation Process

Open the service valves and run the pump to circulate the vinegar through the heater for approximately 45 minutes to an hour. Slow circulation is crucial to effectively remove mineral build-up from the heat exchanger. Refer to your owner's manual for specific recommendations from Rheem. During this step, you may use litmus paper to monitor the pH level of the solution and ensure it is not too acidic.

Step 4: Flushing

After the vinegar has been circulated, turn off the pump and start flushing the system with clean water. This step is essential to remove any remaining vinegar or flushing fluid. Run the water for approximately 5-10 minutes to thoroughly wash out the system.

Step 5: Restore and Inspect

Close the service ports, disconnect the hoses, and restore the power and water supply. Inspect the outside surface of the tankless water heater with a cloth and mild detergent to remove any visible mineral deposits. Additionally, clean the burner like you would any gas appliance to ensure optimal performance.

Regular Maintenance Tips

Conduct Regular Inspections

Regularly inspect the tankless water heater for any signs of mineral buildup, corrosion, or leakage. Early detection can prevent costly repairs and ensure the longevity of your water heater.
