Heatmax History

Founded by an ex-Navy engineer, George Strokes, the company got its start making quartz immersion heaters in Euclid, Ohio in 1952.

George called the company Glo-Quartz®.

Growing rapidly he moved the company to bigger premises in Willoughby and then Mentor. Other factories were opened in Pasadena, California (now closed) and then Tucson, Arizona.

Tom Strokes took over leadership of Glo-Quartz in the mid-70s and moved to roll reduced metal heating element range.

A final legacy, Tom launched a new brand name, Heatmax Heaters, in 2020. The new brand name both better represented the wide range of products we make and challenged the common perception that we were quartz heater specialists only.
