Feature Ground Source Heat Pumps: From Green to Gold By Jim Bullington lectric generation costs continue to rise along with the cost for fuel. There are also more restrictions and regulations on carbon dioxide and other emissions. The resulting focus on alternative energy sources has driven the surge in development of wind, solar and hydroelectric installations. But these technologies are costly and force expensive improvements to the power grid to bring energy to populated areas. A New Technology In 1988, using a federal grant supporting energy ef´Čüciency and renewable energy projects, IGSHPA partnered with seven Oklahoma technology centers to install closed-loop ground heat exchangers and GSHPs, and to train the instructors, students and local contractors and service technicians. 54 Techniques February 2014 equipment presents an alternative to increased generation by using less electricity to do the same work. In recent years, air conditioning manufacturers have been required by legislation to increase the gaining momentum is the ground source heat pump (GSHP), sometimes called geothermal. GSHPs, take advantage of the earth's relatively constant, moderate ground temperature to provide heating, cooling and domestic hot water more ef- peak demand, consumers concerned about reducing their energy costs and preserving the environment, and federal tax credits up to 30 percent of the cost to install GSHPs, the industry has never enjoyed a more positive environment Yet, as Dan Ellis cautioned, "How can you create a market for geothermal if there's nobody there to service the demand?" Ellis is CEO of ClimateMaster, the largest and most well-known manufacturer of GSHPs in the world. Jim Bose, too, expected the need for installers and service technicians to be critical. Bose, who has a Ph.D. in mechanical engineering, is the executive director of the International Ground Source Heat professor and director of Oklahoma State University's Engineering Technology Division. "Sooner or later, everything you do at the university winds up in the hands of a technician." A New Initiative be possible through other conventional heating and air conditioning technoloof Building Sciences, "Geothermal heat pumps use 25 to 50 percent less electricity than conventional heating or cooling systems. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance and do not depend on the temperature of the outside air." With utilities companies and cooperatives concerned about reducing Oklahoma technology centers to install closed-loop ground heat exchangers and GSHPs, and to train the instructors, students and local contractors and service technicians. Funding was limited, however, and the schools were not able to add the necessary service equipment to repeat the training on a continual basis. Recent developments have brought about an effort to revive and expand www.acteonline.org http://www.acteonline.org
