Energy Dynamics, Inc. was founded in 1995 as the exclusive distributor of the Hydron Module product line back when it was manufactured by the Millbrook Hutterite Colony. In 2007, Enertech MFG acquired Hydron Module and began manufacturing that line as well as the GeoComfort line at a facility in Mitchell SD. We picked up the GeoComfort brand at that time and continue selling it and the Hydron Module line to this day. We are very proud of our long history of selling and supporting geothermal systems and doing our small part to grow the industry. In order to better serve our dealers, we have diversified our product offerings in recent years however our niche focus has remained on renewable and high-efficiency systems.
