About Us

Therma-Flow was founded in 1986 by partners Ed Hill and Robert Suffredini who have gained recognition for producing quality contemporary heating products that exhibit the benefits of Yankee ingenuity and practicality.

The Everhot line was acquired in 1990 and continues its timeless combination of state of the art engineering and intuitive design.

In 2010 Therma-Flow acquired the Holt Corporation who specialized in industrial heat transfer products. With the addition of their product lines and service capabilities we can supply a wide variety of solutions to meet all of your industrial heating and cooling needs.

Therma-Flow / Everhot also produces a full line of accessories for the domestic hot water trades
and a high quality, non-toxic anti-freeze for HVAC piping applications.
