GshpCalc, a ground heat pump system design program available since 1993, is now provided
at no cost upon request. It has previously been expanded from vertical ground heat
exchanger design to also include surface water and ground water heat pump systems. It
was updated to metric units, double u-tubes, alternative loop pipe materials, and many
GshpCalc is now freeware along with the many other HVAC and GSHP programs on this website. It no longer
requires registration codes and can be installed on as many computers as you wish. Upon request to
firstname.lastname@example.org, a LoadGshp zipped file and instructions will be provided. Before opening the folder and
initiating setup, it is advised that you delete any previous versions of GshpCalc, including demo versions. If you
have zone (.zon) or ground loop (.glf) files from previous projects that you would like to retain, move them to a
temporary folder until after you install the attached version. Then you can move them back to the new GshpCalc
There is also the possibility that your company firewall may block the email with the program files. Check your
junk mail first and if it’s not there, please provide a personal email address to which the folder can be sent.
My only request is that you sign up to receive our newly revised newsletter, Outside the Loop, along with as
many of your associates as possible by sending names and email addresses to email@example.com.
