What is the recommended frequency for flushing the heat exchanger of my Rinnai water heater?


James Thompson, Water Heater Repair Expert

For optimal performance and longevity of your Rinnai water heater, it’s advisable to flush the heat exchanger at least once a year. This helps to prevent the buildup of mineral deposits which can affect the efficiency and functionality of the unit. However, if your water has a high mineral content, more frequent flushing may be necessary. Always refer to your user manual or consult with a professional for specific maintenance requirements for your model.

If you need assistance with your water heater, the experts at 5 Star Best Plumbing are always ready to help. They offer a wide range of services, including water heater repair and maintenance.
