There are several different types of GHP systems, but the basic premise is the same. You are using the consistency of the Earth’s temperature under the surface to counteract the fluctuations of the temperature on the surface. The people at Global-Greenhouse-
The eBook starts out with an introduction to geothermal heat pumps and how they work. It gives a brief overview of the different types of systems available, and a general discussion of cost. Of particular benefit in this section are the links to sites for United States, Canadian, UK and Australian federal and state incentive programs. There is also discussion regarding which systems are most applicable (or not applicable at all) in which situations.
The authors of the book strongly recommend that you use a qualified contractor to install your GHP system. Not only will you keep your marriage intact, but several of the incentive projects require this. One of the most valuable sections of the eBook is the checklist of items to consider when choosing an design/installation contractor. This alone will save you considerable money and frustration.
Of course, the authors also realize that some people really like to do their own home improvements, not only for the potential cost savings, but also for the satisfaction of contributing their own blood, sweat, and tears to the project. The majority of the book is devoted to helping people who want to do it themselves to design and install a geothermal heat pump system.
There is a very helpful section addressing frequently asked questions as well as a glossary of terms specific to GHP systems. The authors are also generous enough to include the full text of their reference materials as well, significantly expanding the amount of information that you receive. Even if you only have casual interest in the concept of geothermal heat pumps, this book will be a valuable resource, and just might change your mind. If you’re already on the way to a geothermal heat pump system, this book will quickly become one of your major references.
