History of Rheem
In 1925, brothers Donald and Richard Rheem (with some financial help from their brother William) created a co-partnership with the Pacific Galvanizing Company to galvanize steel drums in Emeryville California. Soon after, their plant was enlarged and they created a second co-partnership under the name Rheem Manufacturing Company, this time producing the steel drums.
By 1930, the brothers had been so successful that they incorporated the company, absorbing both co-partnerships and purchasing the Republic Steel Package Company. The merger added a new plant in Richmond, California, and added new products to their repertoire, including boilers and tanks. A year later, the company bought out the John Wood Manufacturing company and began making automatic gas storage water heaters.
Fast-forward to the late 1940s. Rheem had contributed heavily to the war effort and were now switching back to consumer goods. With plants across the US and overseas branches in both Australia and Brazil, the company would continue to grow rapidly, ending out 1960 with 42 plants in 19 countries.
The company split into two divisions in 1973, with the Air Conditioning Division focusing on HVAC applications, and the Water Heater Division focusing on water heaters. These two divisions continued to improve the quality of their lines, producing some of the most innovative and space-saving appliances on the market.
Today, the Rheem Water Heater Division has several lines for both residential and commercial use that sit at the cutting edge of technology and efficiency. They also manufacture water heaters for the Richmond brand.

More efficient than gas, it’s no surprise that Rheem’s electric heaters have more series than their gas heaters. These are among the best on the market, and many are sized for smaller homes.

The top of the Performance series, the Performance Platinum boasts a UEF of .92 to .95 and range from 40 to 55 gallon tanks. Many of these models offer the PlusOne water management system and high-quality anode rods. Models are self-cleaning to help combat sediment buildup.
Rated at .93 UEF, these 40 to 50 gallon water heaters provide high performance without a high running cost. Dual copper heating elements allow for quick response, while premium grade anode rods help increase the tank’s lifespan.
Ranging from a modest 3 gallon point-of-use to 55 gallons, the Professional Classic line covers a wide range of home and mobile needs. All models have high-quality heating elements, with the non-point-of-use models featuring Lifeguard lower heating elements. Many models also include the EverKleen self cleaning device to help combat sediment buildup.
Available in either 40 or 50 gallon models, the Professional Prestige series have all of the benefits of the Professional Classic, plus EcoNet WiFi capability. Dual 5500 watt stainless steel heating elements provide long-lasting performance, and all models feature the EverKleen system.

Hybrid water heaters take the efficiency of an electric heater and crank it up a notch. Depending upon the model you choose, Rheem’s hybrid line may meet NEEA tier requirements.

With representatives of the Professional Classic and Performance series, these models are anything but standard. The Performance series boasts an efficiency of 99.8 percent, making these unbeatable in terms of energy efficiency.

One of the most environmentally-friendly technologies out there, solar-powered water heaters are perfect for sunnier climates. Most of Rheem’s solar heaters use electric or gas backups to provide hot water on cloudier days. In addition, these heaters introduce cold water at the bottom so that hot water stays hot.

Gas heaters have the most replaceable parts, while tankless have the least. Among the parts you might expect to maintain or replace are heat exchangers, burners, valves, anode rods, temperature controls, and valves.
