Rheem is the 80lb gorilla in the Australian hot water market. Australia's biggest hot water brand in its own right, and also owner of many of the other brands on this page. Started in 1936 with after sale service that is second to none.


Rheem was established in Melbourne in 1936 and since 2001 has been owned by Paloma Co, an international water heating and space heating technology and manufacturing.

Almost all of Rheem’s manufacturing is done in Sydney, with smaller manufacturing operations in Perth and Melbourne, however their Gas continuous flow units are made in Japan. While this may seem very small part, a large percentage of Rheem’s sales are in these units.
