2.      Check for Leaks and Drips

Regularly inspect your unit for any signs of leakage or dripping water. Even minor leaks can lead to significant damage over time. If you notice any issues, it’s essential to address them promptly.

3.      Clean the Air Inlet

One of the critical components of your Rheem tankless water heater is the air inlet. Dust and debris can accumulate here, obstructing the flow of air needed for combustion. Cleaning it is essential for efficient operation.

4.      Flush the Unit

Flushing your tankless water heater is a vital maintenance task. Over time, minerals and sediment can build up inside the unit, affecting its performance. Consult your Rheem water heater flushing instructions for detailed steps to do this properly.

5.      Clean the Burner

The burner in your Rheem tankless water heater can accumulate dirt and soot, impacting its ability to heat water efficiently. Cleaning should be done with care, following the manufacturer’s guidelines.

6.      Inspect the Heat Exchanger

The heat exchanger is another critical component that needs regular attention. It’s responsible for transferring heat to the water. Over time, it can become coated with mineral deposits, reducing its efficiency. Cleaning the heat exchanger is essential to maintain optimal performance.

7.      Monitor Water Temperature

Keep an eye on the hot water temperature. If you notice fluctuations or inconsistent temperatures, it could indicate a problem with your Rheem tankless water heater. Address these issues promptly to avoid any inconvenience.

8.      Schedule Professional Maintenance

While homeowners can perform some maintenance tasks, it’s advisable to have a professional Rheem tankless water heater service technician inspect your unit annually. They can identify and address potential issues that you might miss.

Choosing the Right Rheem Tankless Water Heater

If you’re in the market for a new water heater or considering switching to a tankless model, Rheem offers various options to suit your needs. Here are some key considerations when selecting the right Rheem tankless water heater for your home.

Rheem electric tankless water heaters are known for their energy efficiency. Look for models with a high Energy Factor (EF) rating to maximize energy savings.
