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.

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.
