Where Can I Read Reviews On Geothermal Systems?

Or there is Geoexchange, www.geoexchange.org, and they have all kinds of information on heat pumps, including a number of residential and commercial case studies for residential, commercial and school buildings.

At the Oklahoma State University, there is the International Ground Source Heat Pump Association who is responsible for ultimately certifying all the installers and designers of these types of systems and their website is www.igshpa.okstate.edu.
