* Geothermal Conductivity Testing

Before installing a full geothermal system, Pitcher has often performed geothermal conductivity testing to determine if such a system will work appropriately in the soils on site.

It often consists of a single well test on a previously drilled and installed geothermal loop. The purpose is to find out how conductive the earth’s surface is at a specific location. The test well will be a permanent installation, and can be used as a geothermal well in your project if you choose geothermal.

A geothermal conductivity test takes about 48 hours from set up to tear down, and takes anywhere from 24 to 48 hours of actual run time. This allows the machine to get repetitive sample measurements, and also allows the machine to cycle on and off through day and night.
