    Wow a Geothermal (GHP) air conditioning book for the masses. This author really lays things out for the average person to understand.

    Geothermal (GHP) air conditioning is an old technology has been around since the 1940's. The first successful commercial project was installed in the Commonwealth Building (Portland, Oregon) in 1946, and has been designated a National Historic Mechanical Engineering Landmark by ASME. What is amazing is that this green technology has been around for this long. This book will tell you about a renewable source that has the lowest cost per kWH of any distributed thermal technology. Which I find amazing. Energy costs are going to keep climbing year after year. The Geothermal Heat pump (GHP) will allow you to heat or cool your home for pennies on the dollar. This is not voodoo science but real world green savings. The author of this book Jay Egg and his company Egg Systems has been installing Geothermal Air Conditioning for 20 years. If you have any interest in geothermal heat pumps (GHP) be it that you are a contractor, home owner or just a "Green" thumb i would pick this book up.

    Geothermal air conditioning and heating will now be accessible to all who desire to find the most energy efficient heat pumps in the realm of true green renewable energy.

    Geothermal air conditioning has been proven to be the most dependable and energy efficient cooling and heating technology in the world. When properly engineered and installed, this heat pump technology is a remarkably solid renewable source that has the lowest cost per kWH of any distributed thermal technology. This book seeks to, and truly does standardize many of the concerns for geothermal air conditioning and heat pumps that are still troubling the minds of those seeking to understand the merits and incredible possibilities. As in Sweden and Switzerland, Geothermal HVAC systems are well on their way to replacing all other types of cooling and heating. As a disruptive technology, geothermal air conditioning is likely to become a minimum standard sometime in the near future. The Book, "Geothermal HVAC Green Heating and Cooling" also gives a good discussion on how what type of geothermal ground sources work best in differing regions of the the world, and what the associated costs are expected to be. Egg Geothermal systems are being installed and engineered worldwide.

    Clear, informative, and motivating!

    Finally - a book with a comprehensive description about practical geothermal usage. This book describes the benefits, application, and science behind geothermal heat pumps and their ability to heat and cooling our homes and office buildings. This technology has a promising future with the potential to drastically reduce our carbon footprint.

    Just read Geothermal Heating and Cooling (Advanced Copy)

    This book is the first highly readable, comprehensive look at geothermal heating and cooling for homes and small businesses - a poorly known but highly promising technology that offers clean, renewable, domestic energy at a rapid payback. The book is aimed at home and business owners, but is presented with sufficient depth and detail to be a must-read for contractors, installers and anyone else associated with the fast-growing industry. The book simplifies and explains core concepts with dozens of original illustrations, complemented with photos of real-world systems that are saving owners money today.

    In this book, readers learn that almost anyone can take advantage of geothermal heating and cooling, no matter where they live.
    We demonstrate how pay back periods can be remarkably quick, even less than a year in some cases, and that innovative finance tools are available that allow customers to get a new system with no money down, and in some situations even remain net cash flow positive at all times.
    We clearly explain the different types of ground loops being installed, and what loops are best for what conditions. We also explain the different types of heat pumps, air handlers and other hardware.

    We provide instructive, and humorous, case studies of jobs gone wrong and common problems.
    We show readers how to pick a reputable contractor, how to spot cheats, and how to verify the quality of systems. This is no trivial point, because our research indicates that a significant number of companies working in the space provide subpar work.
    We show conclusively why geothermal heating and cooling is one of the "greenest" technologies available for a home or business, and why it is one of the smartest investments too.

    This is no dry textbook; it is written with wit and voice and is full of engaging stories, based on more than two decades of experience in the field.
    Geothermal is perhaps the most misunderstood of clean technologies, but it has one of the lowest barriers to entry and among the best promise. This book is inspiring and eminently practical.

    Jay Egg and Geothermal HVAC

    A few weeks ago I had a chance to meet with Jay Egg, the writer of this book. We talked about replacing my current system with a geothermal unit and the options associated with it. Unlike the competitors in the area (and there aren't many), he didn't just get on the geothermal AC band-wagon. He's been installing geothermal HVAC for 20 years in commercial and residential applications.

    I've been looking at installing a geothermal ac system in my house for quite sometime and thought myself to be educated. While I was right on my basic understanding, he truly showed me his expertise on the efficiency comparison of different types of systems, specifically open loop v.s. closed loop systems. He showed me how thermal retention is a big problem and how the ground where closed loops are installed can heat up over a period of years and cause the unit to become dramatically less efficient overtime. The amount of time he spent on educating me and not selling me was amazing. I can't wait to see what has been laid out for us in this book!

    Great info...really understandnable!

    I just got through scanning through a copy of geothermal hvac...just reading the captions for the illustrations taught me more in a couple of hours than I've learned in the past 30 years. I finally understand why geothermal heating works so well. Great job to McGraw-Hill and the author.
