Cleaning Your Navien Tankless Water Heater: A Step-by-Step Guide
1. Gather Your Supplies: You’ll need the following supplies:
- Cleaning solution (vinegar or commercial tankless water heater cleaner)
- Bucket
- Hose
- Screwdriver
- Wrench
- Gloves
- Eye protection
2. Remove the Cover: Locate the access panel on your Navien tankless water heater and remove it using a screwdriver.
3. Locate the Heat Exchanger: The heat exchanger is the main component that needs cleaning. It’s typically located behind the access panel and may be covered by a protective shield.
4. Prepare the Cleaning Solution: For a natural cleaning solution, use white vinegar. Pour a gallon of vinegar into a bucket. If you’re using a commercial cleaner, follow the instructions on the product label.
5. Flush the Heat Exchanger: Connect a hose to the water inlet of your tankless water heater. Run the hose to a drain or outside. Turn on the water supply and allow the water to flush out the heat exchanger for several minutes.
6. Clean the Heat Exchanger: Remove the protective shield from the heat exchanger. Pour the vinegar solution into the heat exchanger and let it sit for 30-60 minutes. You can also use a soft-bristled brush to gently scrub the heat exchanger, but be careful not to damage the fins.
7. Flush the Heat Exchanger Again: After the cleaning solution has soaked for the recommended time, flush the heat exchanger again with water.
8. Inspect and Clean Other Components: While you have the access panel removed, inspect other components for any signs of dirt or debris. You may need to clean the water filter, vent, or other parts.
9. Reassemble the Unit: After cleaning, reassemble the unit, making sure all screws and connections are secure.
10. Turn on the Power and Gas Supply: Turn on the power and gas supply to your Navien tankless water heater.
11. Test the Unit: Run hot water from a faucet to ensure the unit is working properly.
