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 […]

NYC Sets Precedent for Requiring Geothermal Certifications

The New York City Council recently passed local law 0609-A-2015 stating that all new city buildings or city-owned buildings undergoing a HVAC retrofit must use geothermal if the ‘geothermal system has the lowest net present value of all alternatives considered.’ This legislation is a big deal for designers and installers of geothermal projects because it requires a minimum […]

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, […]
