Big Green: Geothermal vs geoexchange

Mon Oct 27 08:57:36 EDT 2008

Here's another vote with Geoff, we call the ground source heat pumps
geo-exchange.

Properly speaking, geothermal energy is derived from heat in the earth's
surface.  Hot springs and the like,  a byproduct I presume of volcanic
action
http://www.earthpolicy.org/Updates/2008/Update77_data.htm#table7

In the construction industry we lazily refer to ground-coupled heat
pumps as "geothermal".  Easy & catchy, but wrong.  Is there a simpler
way to refer to this while being more accurate and avoiding the
confusion with real geothermal?

I try to use "geo-exchange" for earth coupled heat pump systems.  It's
tough due to the Construction Industry and society in general using the
"geothermal" word commonly but incorrectly.  You are right- geo-thermal
is tapping direct earth thermal energy as per Iceland.

Yes,

I believe that the terminology that you're looking for is "ground-source
heat exchange"

Dean:

Ground Source Heat Pumps (GSHP) or ground -coupled heat pumps.  As much
as I have resisted saying "geothermal" systems everybody is doing it so
I must admit  to be understood I have buckled.

Cheers,

Ralph
