Rheem Manufacturing Company was established in the mid-1920s when brothers Richard and Donald Rheem acquired a galvanizing plant in San Francisco, California. In the 1930's, Rheem began manufacturing water heaters, and by 1936 had coast to coast distribution. During the 1940s and 1950s, the company increased its product line to include space heating units for homes, oil furnaces and air conditioners.
