Deep Boreholes in GSHP Systems: Pressure Considerations & Installation Practices

Factors such as space limitations are forcing engineers to utilize deep boreholes to meet design requirements for Ground Source Heat Pump (GSHP) systems.
In such cases, hydrostatic pressures must be considered to ensure successful installation can take place. This short course, led by expert Ryan Carda, P.E., focuses on the necessary calculations along with the recommended […]

3 Ground Source Heat Pump (GSHP) System Design Questions

Expert Instructor Ryan Carda discusses vertical boring systems, horizontal ground loops and Energy Recovery Ventilator ducting on the IGSHPA Certified GeoExchange Designer (CGD Plus) Training discussion board…
Student 1: Would you say that the addition costs associated with vertical boring are greater than the cost of extra piping necessary for a horizontal system?

Ryan Carda: To a point – HDPE pipe itself is […]

Improving Accuracy with Ground Loop Design Flow

Improving Accuracy with Ground Loop Design Flow
Proper geothermal heat exchanger design is not a simple matter.

The following piece was written by Doug Carruthers of Geo-Connections, Inc.
Systems, especially big commercial systems, have a lot of moving parts and the chassis onto which they are all strapped is flow.

Flow through the coil, flow through the ground loop, […]
