Rheem. Tested. Trusted. Tough.
A History of Comfort
Brothers Richard and Donald Rheem founded Rheem Manufacturing Company in Emeryville, CA, in 1925. While the company has produced a number of products in its nearly 100 years of operation, Rheem is currently the only manufacturer in the world that produces heating, cooling, water heating, pool & spa heating and commercial refrigeration products, and it is the largest manufacturer of water heating products in North America. It isn’t easy building comfort equipment that’s tough enough to perform for homeowners and businesses day after day, year after year—but it’s the only way they do it.
From industry-leading technologies to next-generation energy efficiencies, Rheem has been a pioneer in developing some of the most innovative advancements in heating, cooling, and water heating. With a long list of award-winning solutions, Rheem continues to deliver advanced comfort, savings, and experiences to our customers—just as we’ve done for nearly 100 years.
