Geo Heat Pump Applications

Three for the money—so let’s go!

(Geothermal Can Satisfy Any Building You Want) CaliforniaGeo 12-14–18 When some members of the public first hear about geothermal heat pumps (GHPs) as some sort of thermal efficiency miracle, it’s probably tied to a specific type of building.  And if that type is not one that is likely to serve them in the future, their […]

Renewable power and geo heat pumps—a marriage of more than convenience

CaliforniaGeo 6-21-18 (Happy solstice!) What’s the most efficient thermal technology for space heating, cooling, and water heating?  It’s a geothermal (or ground source) heat pump (GHP).  Long ago recognized  by the EPA as holding this title, the heat source’s / heat sink’s thermal energy available to a GHP is free, renewable, sustainable, and available everywhere […]

The Importance of Bi-National Industry Standard CSA 448 – Series 16

CaliforniaGeo 8-15-17  An Operational Roadmap- The importance of recognized standards in every organized business or industry is the only way to ensure that outcomes fall into what we would refer to as norms, or acceptable performance.  Consistent results are what matters.  The U.S. Public Health Service Telegraphic Code of 1915, (shown at right), made the […]

A municipal complex gets GeoExchange® via a pond

CaliforniaGeo 8-3-17 Worn out infrastructure? Struggling with an HVAC system composed of various technologies of ages up to 25 years in their main municipal headquarters building, the City of Fort Collins, Colorado installed a complete geothermal heat pump retrofit.  The new system will provide a carbonless heating and  efficient cooling system for over twice that […]

An authoritative study answers a critical question

CaliforniaGeo 6-20-17 [This study was conducted by Oklahoma State University’s Jeffrey Spitler and Laura Southard.  Data processing was overseen by Xiaobing Liu of Oak Ridge National Laboratory.] A major retrofit project to the U.S. headquarters building in Atlanta, GA for the American Society of Heating and Refrigeration Engineers was envisioned as a “split system” but […]

De-bunking Myths About Geothermal HVAC

CaliforniaGeo 4-13–17 [On November 21, 2014, Don Penn, President of Image Engineering Group in Grapevine, TX made a presentation to the annual conference of the International Ground Source Heat Pump Association (IGSHPA) regarding 10 myths held by the public regarding geothermal heat pumps.  This blog entry deals with a selection of five of those 10.] […]

What is a grouted, geothermal bore hole?

CaliforniaGeo 12-6-16 What They Are- When you want to exchange thermal energy with the earth, you must make an underground connection to tap it as your thermal battery.  There are multiple kinds of geothermal heat exchangers (GHEXs), but today we’ll look at the type known as grouted geothermal boreholes.  All photos in this post come […]

Geo system provides direct cooling of an emergency operations center in Florida

Geo Exchange® provides direct cooling via groundwater CaliforniaGeo 11-16-16  The Pinellas County Emergency Operations Center in Florida isn’t any different than similar facilities across the country. It needs to be up and running—no matter what. However, because cooling is such a large part of the energy load here, the facility sought to attempt operating cost reductions late […]

First-ever geothermal heat pumps at Edwards AFB

A high-tech government facility adds its (first ever) geo heat pumps at Edwards AFB for its fuel processing lab. The first ever  geothermal heat pumps at Edwards Air Force Base has landed on the high desert near Rosamond, California.  This site of aviation history has been pivotal in the development of all kinds of high speed, high altitude aircraft, […]

A Quarry Lake provides heat sink cooling for Nashville, TN Airport

An abandoned quarry lake saves the Metropolitan Nashville Airport Authority $430,000 per year for airport terminal cooling.   The former Hoover Quarry is a 43-acre lake located east of Donelson Pike and Nashville International Airport (BNA) Runway 2R/20L. The average depth of the quarry lake is 150 feet, containing approximately 1.5 billion gallons of water. At […]
