A gold mine of info with something like 60-70 color illustrations. The book is wide too.....making it easier to read compared to a narrow book with more pages and little info on each page.

The recent Ask This Old House segment on residential geothermal got my attention. Richard Trethewey gave a great intro. He visited a homeowner who replaced his old propane heating system with an open loop geothermal system. The owner said that the price of propane tripled since he bought the house. Based on that no-cap 30% tax credit that Trethewey mentioned, I started searching for further info on the subject that led me to this book. Not sure where the home that Trethewey visited was but the owner said his payback period was 6 years and he said that he now saves about 60% on heating compared to the old system.

My old oil fired steam boiler which originally used coal has served me well for a long time but it is getting too expensive.....it's time for an upgrade. Needed to come up to speed and found this book with more info than I can absorb at one time. Didn't realize that sizing for geothermal is so critical to get an efficient running system but now understand why. If the size is no good those electric auxiliary strips will kick in and make my oil bill will look cheap compared to my electric bill.

Thinking about a vertical closed loop system. In chapter on Homeowner's Dilemmas the analysis on whether to use a single 450 ft or three 150 ft boreholes will be a big help in making that decision. Didn't know anything about formicary corrosion of heat exchangers, Reynolds numbers, turbulence, TXVs, superheat, filter-driers, accumulators, well pump sizing, pump BEP, CPH and other stuff but I feel I can now work with the installer and know if everything is being installed right. I've learned that you can't just close your eyes and cross your fingers when it comes to installing one of these systems....you got to do your homework!

As a Licensed Professional Engineer, the book "RESIDENTIAL GEOTHERMAL SYSTEMS: Heating And Cooling Using The Ground" is well illustrated and answers most any question a person could ask in regard to Geothermal installations. Of course the nature of the area available for instillation will have the most influence on installation costs and system efficiency.

This was one of two books on Geothermal Heating & Cooling ordered through Amazon with expedited shipping because my current system was out of order. Very fortunately, they arrived 24 hours before the contractor arrived to start making measurements . The two books saved me a fortune, because the contractor had low balled his verbal estimate to two-thirds of the real cost. When challenged by the two books in front of him, the price estimate tripled. Needless to say, other arrangements have been made.

There is a lot of technical info. in this book,BUT useful. Any home owner considering geo thermal should study the information. I have come to realize there are installers who are not well versed on these systems. Before one makes the investment in a system, read this book.

Someone needs to do a comparative review of the several on show, rather than muttering "Interesting" at the one they receive. I found this one lean on detail, lousy in graphics and very low-brow in language; a lot closer to extended brochure than to manual.
View this book, scheduled for release July 2013, as a likely superior alternative: Modern Geothermal HVAC Engineering and Control Applications

Book was informative, supplied equations for the logic it was explaining, and was easy to follow. If your looking to make your home heating and cooling system "Green" this is a must read.
