HOW TO FLUSH AND MAINTAIN NAVIEN TANKLESS WATER HEATER?
As a certified contractor for Navien, Azerplumb understands the importance of maintaining your tankless water heater. Regular descaling is crucial to ensure your system operates efficiently and lasts longer. In this guide, we’ll walk you through the process of descaling your Navien tankless water heater.
Why Descaling is Important
Over time, mineral deposits, primarily calcium and magnesium, can build up inside your tankless water heater. This scaling can reduce the efficiency of your unit and lead to higher energy costs. By regularly descaling your water heater, you can prevent these issues and ensure optimal performance.
Signs Your Tankless Water Heater Needs Descaling
1. Reduced Water Flow: If you notice a decrease in water pressure, it might be due to scale buildup.
2. Fluctuating Water Temperature: Inconsistent water temperature is another sign that your heater needs descaling.
3. Error Codes: Many Navien models will display error codes related to scale buildup.
Steps to Descale Your Tankless Water Heater
Materials Needed:
• Descaling solution or white vinegar
• Submersible pump
• Two 5-gallon buckets
• Hose connections
Instructions:
1. Turn Off the Power and Water Supply: Ensure the unit is turned off and the water supply is disconnected to avoid any accidents.
2. Connect the Hoses: Attach hoses to the service ports on your Navien tankless water heater.
3. Prepare the Descaling Solution: Mix the descaling solution according to the manufacturer’s instructions or use undiluted white vinegar.
4. Pump the Solution Through the System: Place the submersible pump in a bucket filled with the descaling solution. Connect the pump to the hose leading to the inlet service port and run the other hose from the outlet service port into the second bucket. Run the pump for about 45 minutes to an hour to circulate the solution through the heater.
5. Flush the System: After descaling, flush the system with clean water to remove any remaining solution and dislodged scale.
6. Reconnect and Restart: Reconnect the water supply and turn the power back on. Check for any leaks and ensure the heater is operating correctly.
