Monitoring and verification of an installed heat pump

The GxTracker™ provides residential and light commercial ground source heat pump (GSHP) users with an affordable,  easy-to-install monitoring and verification system that shows real-time data about the heat transfer and environmental and cost benefits associated with their GSHP heating and cooling system.

The GxTracker™ can be readily installed onto an existing heat pump.  System monitoring and verification will help you:

  • Track entering water temperature (the leading indicator of performance) and get email alerts if entering water temperature goes outside of user-specified limits.
  • See your GSHP system performance with BTU production, electricity consumption.
  • Show your carbon offsets calculated from actual operating data and accounting for your local electric grid carbon intensity.
  • Work more effectively with your installer if service calls are necessary.   Data graphs can be shared with installer so they can see a record of system operating conditions to help diagnose problems, should they arise.
  • Share your success with family and friends who might be interested in geothermal heating and cooling.

The GxTracker™ can be customized to meet your monitoring needs.

  • Up to 3 ground source heat pumps (water-to-air or water-to-water)
  • Three options for tracking electrical usage
    • Measure heat pump runtime anduse manufacturer specifications to model kWh.
    • Measure current and compute kWh by multiplying by voltage (assumes power factor of 1).
    • Submeter electricity consumptions using a WattNode® with pulse output.
  • Three options for tracking flow rate:
    • Use constant design flow rate (most common)
    • Measure flow with a vortex shedding flowsensor
    • Meter flow with a pulse output flow meter.

  • Our Mission

    Ground Energy Support strives to provide high quality data and objective analyses to support the ongoing development of ground source heat pump technology.
  • What customers say:

    • Your system has been absolutely crucial in helping me monitor problems as they occur, right at my fingertips. Doing without it would be like driving a car without any gauges. - Pete W., Homeowner
    • It is interesting to follow the data and understand what the system is doing. …Love this information, wish I had known about it before – I am really glad I installed it. – Steve H., Homeowner
    • I look at it every day! -- Paul B., Homeowner
    • I did not know that my oil heat circulator was cycling on every 6 hrs until this monitoring showed me that. Why add heat 4 times a day in summer?! I turned it off after GES alerted me to what was happening.” Pete Tavino, P.E., IGSHPA Instructor
    • I have been checking the GxTracker, and noticed that the total heat rejected was less than it should be. I checked it out and the machine was a little low on refrigerant so I recharged it. I checked the website and system efficiency improved by almost 40%, cool! -- John S., Geothermal Professional
    • We just ran the AC for first time last night … Pretty cool to see all the data! -- Greg M., Homeowner
    • Well, more “kudos” to Ground Energy Support. I just got a call from my installer who will address this issue. Again, thanks so much for everything. --Joseph P., Homeowner
