History of Thawzall, LLC, cont.
The plumber, Jerome Jakobson, developed his version of a portable hydronic heat system using a low
pressure closed loop system. The first of hundreds of machines to come was produced that first winter. Because Jakobson felt that he and a better idea than a competing model, he applied for and received patent #5,964,402 for his portable hydronic heater in 1999. This patented system uses a manifold fluid distribution system that features quick disconnects and multiple heat zones.
Jakobson, an avid hunter and fisherman, decided to sell his company, known then as T.H.E. Machine
Company, to a group of five local investors from the Alexandria Minnesota area—in order to pursue
his passions. On July 1, 2007, the company was formed with new ownership and management and became known as Thawzall, LLC.
The new management team is committed to listening to its customers for their ideas regarding product innovation and simplicity. By listening carefully to our customers, we are confident that in the next
generation, Thawzall heat units will exceed our customers’ expectations and set new standards for
quality and innovation in the industry for portable hydronic and flameless heater technology.
All Thawzall employees are committed to excellence in manufacture and customer satisfaction. We
take great pride with every machine we build!
