AIR -TO- AIR AND GROUND SOURCE HEAT PUMPS
_________________________________________________________
You probably shouldn't attempt to perform a ground source heat pump installation on your own without the use of professionals. This is also true of many other specialized trade categories in residential construction. As a reminder of this, most heat pump equipment manufacturers won't sell their wares to individuals—only to qualified installing contractors or organizations employing same. This is appropriate.
Manufacturers want professional installations and satisfied customers. This helps extend the technology's reach by beneficial word-of-mouth. Search the technical equipment horizon and if it's more complicated than plugging in a cord to a wall receptacle, manufacturers of autos, aircraft, sawmills, X-ray machines, and many other products prefer that trained and certified persons install, use, or maintain the device.
All that having been said—if you are going to be a knowledgeable consumer, better able to communicate with bidding professionals through your understanding of ground source HVAC technology. . . then it's important to learn all you can in advance. That is why the how-to videos below are provided.

GROUND SOURCE HEAT PUMP BASICS--
CERTIFICATION PROGRAM FOR GEO EXCHANGE DESIGNERS (Part 1) The first four minutes of this video with Dr. Jim Bose of Oklahoma State University does a great job of showing how renewable solar heat can be captured from underground by fluid-filled pipes. The remainder covers the thermal physics of energy efficiency in our economy. (video 9:46) CERTIFICATION PROGRAM FOR GEO EXCHANGE DESIGNERS (Part 2) Dr. Jim Bose of OSU continues with coverage of various HVAC efficiency measures and an overview of ground source heat pump technology from small residential to large commercial installations. Underground pipe sizes, deployment, and fluid circulation are covered. (video 9:42) HEAT PUMP MECHANICS A lengthy and effective portion of a great Web site explaining the mechanical properties in operation of heat pumps and ground source heat pumps. By the Virginia Deparment of Mines, Minerals and Energy and Virginia Tech. GROUND SOURCE HEAT PUMP INSTALLATIONS-- Home 1 DRILLING AND PLACEMENT OF (1 of 6) VERTICAL BOREHOLES This series begins with drilling for a new home in Stillwater, OK. By IGSHPA and ComfortWorks. Narrated by Gerald McClain. (video-slides 9:40) Home 2 GROUTING VERTICAL BOREHOLES WITH SPECIALIZED EQUIPMENT A Tremie tube is forced down each borehole that contains ground loop pipe. Grout is mixed and pumped into the bottom of the bore up to the top. Then, the Tremie tube is removed, leaving the bore hold and it's pipe ready for header connections.
