Navien Tankless Water Heater Routine Maintenance & Flushing Service

As an authorized Navien service company, we recently completed a routine maintenance visit for a Navien tankless water heater. Regular professional servicing helps extend the life of the unit, protect the heat exchanger, and maintain peak operating efficiency.

What Was Performed

• ✅ Full flushing (descaling) service
• ✅ Circulation of a professional descaling solution through the heat exchanger for approximately 30 minutes
• ✅ Proper neutralization of the acidic solution using an alkaline agent before disposal (approximately 10 minutes)
• ✅ Removal and light cleaning of the flame rod, which remains in excellent working condition
• ✅ Inspection of air intake, exhaust termination, and condensate drainage with no debris or blockages found
• ✅ System restart and verification of operating parameters

Service Duration

The total service time for this maintenance visit was approximately 50 minutes.

System Condition & Recommendations

The water heater is three years old, and this was its first maintenance service. Overall, the unit is in very good condition. Annual flushing is strongly recommended to prevent scale buildup, protect internal components, and ensure reliable long-term performance.

The flame rod typically requires replacement every 4–5 years. This is a low-cost part, and planning ahead helps avoid unexpected service interruptions.

If your Navien tankless water heater has not been serviced in several years, scheduling routine maintenance now is the best way to preserve efficiency and avoid costly repairs in the future.
