This seminar will cover a brief history of direct exchange (DX) geothermal along with the recent advancements to the technology that has begun a new era in direct exchange geothermal. Direct exchange systems have several design & installation advantages over the alternative water-source geothermal technologies. Learn the advantages of this leading technology that differentiates the contractor from the rest of the competition. It will address common myths that surround the 70+ year old DX geothermal designs, as well as ongoing research in DGX commercial hot water systems and the use of natural refrigerants like carbon dioxide (CO2).
