  • Energy Efficiency and Performance Comparison

State heaters generally offer superior energy efficiency compared to Rheem. Most of State’s models meet or exceed federal standards for energy efficiency, reducing running costs and being eco-friendlier.

On the other hand, while Rheem does have energy-efficient models, they may not consistently match the efficiency levels of their State counterparts.

Energy-efficiency is a key factor when shopping for a new water heater. Here is how Rheem and State compare:

  • Technology and Innovation

Rheem tends to lead in technological innovation, with several models boasting advanced features like WiFi connectivity, which allows for remote control and monitoring, and self-cleaning systems, which prolong the heater’s lifespan.

State, while not as technologically forward, focuses on producing reliable and straightforward water heaters.

  • Price and Affordability

There is a noticeable price difference between the two brands. Rheem generally offers more affordable options, providing a diverse range of heaters that can fit into most budgets.

State heaters, while tending to be more expensive, justify their cost with superior efficiency and excellent warranties.

  • Availability

When it comes to availability, Rheem tends to have the upper hand. Their products are easily accessible across numerous online and physical retailers.

State, on the other hand, while available in a variety of outlets, might not be as widely distributed, potentially limiting your purchasing options.

  • Available Sizes and Installation

Rheem and State cover all the standard capacities needed for homes:


  • Residential tanks from 6 to 80 gallons
  • Slim profiles for tight spaces like closets

Rheem’s warranties aren’t insignificant, but they may not always match the coverage offered by State.

In summary, the choice between State and Rheem water heaters hinges on what you value most in a water heater. If energy efficiency and warranty coverage are your top priorities, State might be the better choice.

Conversely, if affordability and technological features are your main concerns, Rheem could be a more fitting option.

Which Is Better For You?

For those wanting the latest in energy savings technology, customization, and premium performance, Rheem is likely the better choice but comes at a higher cost.

Homeowners focused purely on reliable hot water at the lowest upfront price will be happy with a State water heater.

Make sure to consider your usage needs, fuel source preferences, and installation requirements as you decide. And review all warranties closely, as the tank and parts coverage are similar between both brands.

If your top priority is upgrading to a highly efficient system, Rheem wins.

But State provides satisfactory performance for many homeowners at an affordable price point.
