Geothermal Accredited Installer Workshop

Learning to install Ground-Source Heat Pump (GSHP) systems will keep you competitive in a market forced to deal with rising energy costs and resource depletion. Installer accreditation enables you to open new markets and offers customers a low-maintenance, economical, and environmentally friendly alternative for their space conditioning needs. With more than 30 years of experience teaching these workshops, accrediting thousands of installers, and developing the industry standards, IGSHPA has maintained close ties with Oklahoma State University, and pioneered training in GSHP installation.

Who should attend?

The three day comprehensive Installation Workshops are designed for GSHP installers, contractors, dealers, home builders, manufacturers, distributors, architects, heating cooling mechanical engineers, trench/water well drilling contractors, and anyone who desires a working knowledge of this innovative technology. Representatives from public utilities, and rural electric cooperatives can also benefit from training. Information gathered from the workshops can help utility representatives serve as a source of information regarding money-saving concepts.


Upon successful completion of the workshop and passing the IGSHPA installer's exam, you will be issued IGSHPA accreditation as an installer of GSHP systems. You will receive an installer's card and a certificate for 3 years. Also you will receive a 1 year membership with IGSHPA after you have completed all the requirements of the Installation Workshop.

Garen Ewbank  

Garen developed the in situ thermal conductivity testing methodology used by the GSHP industry to size and design ground heat exchangers (GHEX). Garen is co-owner of the patented Advanced Thermal Conductivity Method (ACTM) that shortens the testing duration and quantifies the diffusivity. Garen has installed GHEXs throughout the U.S. and consulted throughout the world on GHEXs. Garen has been a primary investigator/collaborator on numerous applied research projects on the GHEX, borehole resistance and thermal storage, Garen has peer reviewed several software applications to size and design the GHEX. Garen trains for IGSHPA in all courses domestically and internationally.

Garen is managing member of Ewbank Geo Testing, LLC, member of GeoAire International and at large managing member for The GreyEdge Group, LLC.

Applying a “Systems” approach to GHPC design is a key to making systems function economically, correctly and with a minimum carbon footprint. This requires complete integration of the Ground Heat Exchanger(GHE), mechanical piping, and controls. As an early adopter of this approach, we have been able to integrate systems from several HUD homes to University campuses. Mixed use applications in City-scape and Campus environments provide ideal opportunity to bring together wasted energy collection and re-use that energy (Energy HighwayTM); significantly increasing System Coefficient of Performance (SCOP). This approach not only increases efficiency (or Least Energy PathTM) but also dramatically reduces greenhouse gas emission and water consumption.

Areas of Expertise:

  • Assessments to determine economic and technical feasibility of GSHP systems for commercial GSHP projects
  • Design and implementation of ground source heat pump systems and associated ground heat exchangers
  • Large scale Distributed (District Energy Systems)
  • Control and Sequence of Control review and optimization
  • Forensic analysis of failed or poorly operating GSHP systems
  • Workshops and training seminars for designers of commercial and residential GSHP systems (Accredited IGSHPA Trainer)
