Rheem began operations in Australia in 1936 as an overseas venture of Rheem Manufacturing, an American drum manufacturer.  In 1939, Rheem Australia manufactured its first gas water heater in the inner Sydney suburb of Waterloo and production of electric water heaters commenced in 1945.

Over the years, the Rheem product range has diversified to include the latest in solar, heat pump and high efficiency gas water heaters. Today, Rheem Australia is the market leader in the Australian water heater industry, with a focus on design, manufacture and delivery of customer-focused, cost effective water heating solutions.
