Despite having fairly similar looks, the Rheem Performance and Performance Plus water heaters have many different features to set them apart. In this section, you’ll learn about these dissimilarities to help you with your buying decision.

Quality and Performance

Both the Performance and Performance Plus models offer up to 98% uniform energy factor (UEF). This measurement provides users with a quick look at the performance rating of these water heaters. The difference lies in the materials used for the heating elements.

The Performance Plus has the upper hand over the Performance water heater for it uses a better copper construction for its dual-heating system. On average, the Performance provides about .59 to .65 UEF by using two pieces of copper and anode rods. On the other hand, the Performance Plus has a more consistent average UEF of .93.

Upon seeing those numbers, the Performance Plus also typically lasts longer than the Performance model, thanks to the better efficiency. You can also read our post on how long does a Rheem water heater last to gain insight into its average lifespan.

Heat Source

The Performance water heater has a gas tank fueling the heating process, providing warm to hot water to household members and guests. This heat source often provides fast water heating capabilities while remaining energy efficient. Also, users can still take advantage of hot water during a power outage with the Rheem Performance.

However, owners need to attach Performance water heaters to gas lines. Expenses can increase if users decide to connect a Performance model to a propane tank instead of a city gas line. Plus, it can be tough to clean and maintain a gas water heater since it uses fire to heat the water in the plumbing system.

As for the Performance Plus, this water heater uses electricity to provide warm and hot water to a property. Take note that it’s not possible to use this model with no electricity without a backup power supply. Still, it typically provides clean operations, increasing its lifespan and providing convenience for its routine cleaning and maintenance practices.

Keep in mind that electric heaters like the Rheem Performance Plus water heater also have a slower water-heating speed than the Performance model.

Accessibility and Convenience

The Rheem Performance water heater typically doesn’t have an LED screen. So it can be quite challenging to obtain the ideal water temperature for each user. Also, it generally has a pilot light, which may require manual relighting if it goes out.

On the other hand, the Rheem Performance Plus normally has a built-in display. That feature allows users to look at and fine-tune their water temperature preferences during use.

So in a bout between the Rheem Performance and Performance Plus, when talking about their accessibility and convenience, the latter might be a better choice for certain customers. Although, the Performance model can still be a good choice if users won't mind the extra effort in maintaining the unit.

Manufacturer Warranty

If bought from the manufacturer or a reliable supplier, both the Performance and Performance Plus water heaters from Rheem have the brand’s limited warranty. Despite coming from the same company, the Performance model only has a 6-year coverage while the Performance Plus has 9-year coverage.

Nonetheless, these two water heater models should share the same warranty inclusions and exclusions. Some of the things that this limited warranty doesn’t cover are:

  • Service trips to teach users the steps to set up, use, or care for the water heaters.
  • Incidents caused by improper installation.
  • Damage, faults, and malfunctions are caused by user negligence.
