A Brief History Of Rheem Water Heaters

You would have to look back to 1925 to see the start of Rheem Manufacturing. As is the case with many businesses, they had a humble beginning when founded by the Rheem brothers, Richard and Donald.

They got their start with a partner in Emeryville, California. That company, Pacific Galvanizing, was eventually purchased by the brothers. By 1930, The Rheem Manufacturing Company was in business.

Rheem Manufacturing continued to acquire other companies over the next few years and became an international company when they opened a plant in Sydney, Australia, in 1936. At first, they were building steel shipping containers, but they added water heaters to their line of products in 1939.

During WWII, Rheem focused much of its efforts on manufacturing aircraft parts and building ships. After the war, they again went back to manufacturing water tanks, including making a glass lining to their water heater tank in 1954. 

During the next few decades, they continued to expand their business and product line. Today, they are the largest North American manufacturer of water heaters. They also continue making many other products, including spa and pool heating, air conditioning, and commercial refrigeration units.

One option is to look at the specific model you plan on purchasing on the Home Depot website. They offer a 5-star rating system and comments from customers. You can find additional comments on the website.

As is the case with any reviews posted online, you are more likely to see a negative review than a positive review. Customers tend to be motivated to leave a review when they have a negative experience. By looking at all of the reviews, you get a better top-down view of what to expect.

Another way to verify the reliability of a Rheem water heater is to speak with a local contractor.

As you will see, there is a limited warranty available on all Rheem water heaters, so you may want to consider replacing the unit when it has expired.  At the very least, speak to a contractor to see when the water heater needs replaced. They can watch for deals that may help you save money on that necessary work.
