The book covers geothermal systems and controls from their introduction to the U.S. during the early 1970s to the multistage ultrahigh-efficiency systems of today.
A best-practices guide for the design, installation, and maintenance of geothermal systems is available from RSES, the education, training, and certification association for HVACR professionals.
Drawing on author Jeff Persons’ more than 30 years of field experience, “Understanding Geothermal Systems” covers geothermal systems and controls from their widespread introduction to the United States during the early 1970s to the multistage ultrahigh-efficiency systems of today. Both open-loop and closed-loop applications are covered, as are subsurface geology, loop design, water chemistry, and antifreeze solutions. Emphasis is placed on identifying common installation and service mistakes and learning from them.
The cost of “Understanding Geothermal Systems” is $45 for RSES members and $55 for non-members. To order, call 800-297-5660, or visit http://bit.ly/RSES_geo.
