Abstract: Technical assistance in a preliminary design and economic evaluation of a geothermal heating system was provided. The use of a downhole heat exchanger was evaluated, with the objective of reducing costs in this first stage of the project, but was abandoned. The low resource temperature and lack of sufficient aquifer data were the reasons for abandonment of the downhole heat exchanger concept. The use of surface plate heat exchangers was selected as the preferred approach for utilizing the geothermal resource. Brine will be passed through three plate heat exchangers in the building basement. Separate loops of clean circulating fluid will be used to extract heat from the brine in three heat exchangers, with the loops providing heat to the building, a hot tub, and a deicing system. The cooled geothermal fluid from the heat exchangers will be injected to an isolated injection zone at the bottom of the production well. Aquifer tests are required to develop final pump sizes and process flows. The information developed from the work tasks of this project is presented.
