Modern Geothermal HVAC Engineering and Control Applications

As a Geothermal engineer and installer I found Modern Geothermal HVAC an excellent text for the advanced geothermal expert. Mr. Eggs first Geothermal book is an excellent introduction to Geothermal heating and air conditioning and a perfect guide for the consumer to become knowledgeable about selecting a geothermal system and working with a contractor. This new textbook combines the world class expertise of Mr. Egg, Mr. Orio and Mr. Cunniff. Modern Geothermal HVAC engineering and control brings detailed engineering knowledge to the geothermal designer and installer that is often lacking. As a Geothermal professional I see many costly geothermal systems installed that do not function properly due to a lack of engineering knowledge. This book is an excellent guide for the technically savvy that have an interest in Geothermal HVAC to the graduate engineer or HVAC instructor that needs an excellent educational resource. It should be a standard in any advanced HVAC curriculum. I found the sections on Standing Column Wells, controls, load sharing and Hydronics particularly excellent. This book also does an excellent job of advancing the use of open loop and Standing Column well systems versus the age old and often poorly designed or inappropriately selected, sized and installed closed loop systems for systems requiring more than 3 to 4 Tons. Geothermal heating and air conditioning are rapidly becoming the superior solution worldwide for new homes, commercial and industrial facilities. It is elegant, clean, efficient and the most reliable technology available. This book is a must buy for anyone in the Geothermal or HVAC industry.

It describes several approaches for heating/cooling using geothermal techniques. Much more like a textbook that a practical guide, not a criticism, just my observation.I purchased it with the intent of acquiring a complete understanding of the design principles of the systems to geothermally heat and cool a concrete structure in central florida. I do not feel I came away with that, BUT I did receive a very great deal of information about the elements involved.

Easy read, not overly technical. Presents a valid qualitative and quantitative comparisons of open -re-injection wells, standing column wells and closed loop. Discusses the necessity of site specific geothermal requirements. Further provides one of the few books that discuss the entire heating ventilation and air conditioning (HVAC), including digital controls. Also the chapter on incentives and tax savings, while some what dated, is still a convenient and useful summary of these geothermal benefits

This is certainly one of the best, if not the best, book on geothermal HVAC on the market today. It is comprehensive in its information and especially valuable for understanding the loop field. Various options for loop fields are discussed and explained. I recommend this book to anyone interested in learning about geothermal. However, I think the author does stretch a bit - there is a fair amount of repetitiveness where one chapter will cover a lot of the ground a previous one did, even using similar sentences and paragraphs. There is also some superfluous discussion of general HVAC toward the back of the book that seems like filler.I also disagree with the author's vehemence about not recommending closed-loop geothermal systems for commercial projects. Standing columns and wells are fine in Florida and Northeast, but in the Midwest where the geology is different and cooling a little less dominant, closed loop systems can be effective. There are also add-ons to closed loop systems such as Greensleeves LLC's GeoModule software that can make closed loop systems efficient and effective even in very cooling-dominant applications.But weighing the pluses and minuses, this is a book worth reading.

This book was helpful to understand all of the ways Geothermal can be applied, no matter where you live. It should be the first thing an individual considering geothermal should purchase to help them understand geothermal heating and cooling. I believe that after reading through it's pages, it will become clear that geothermal heating and cooling is the best way to reduce energy consumption, reduce CO2 emissions, and increase the comfort in our homes and buildings.

I expected a technical book on Geothermal systems. Regrettably this is on the level of a power point presentation provided for a 1 day seminar. Poorly illustrated. Pictures of: an indoor pool (Figure 1-9), a women sunning herself on the beach (Figure 8-11) a guy and a girl sitting by a space heater (Figure 8-3), a young women looking out a window (Figure 8-20), an older guy hugging himself (Figure 8-19), the Author's family in a restaurant (3-24), an illegible photo showing the inside of a geothermal heat pump, people warming their hands over a radiator (Figure 8-10), countless trivial and barely legible diagrams that look like they were created with a children's CAD program are substituted for example wiring diagrams, detailed piping diagrams, control diagrams, equipment descriptions etc.This s laziness. Good technical description is difficult. Professional looking detailed and technically accurate and telling illustrations take are time intensive.Regrettably I purchased this from amazon.

Its a hard read, Jay Egg wrote a manual, not a novel so its what I should have expected.

I am a General Contractor that builds custom homes and our niche is being energy efficient. What a bundle of knowledge. I wish I had read this before all the time I wasted on other research I did. Great book, Jay. I look forward to working with you on a project.

excellent information
