Monitoring Geothermal Heat Pump Performance

Overview:

This paper discusses how portable data logging technology can be used to measure, record, and document the performance of geothermal heat pumps, and provides specific case study examples of how the technology is being applied in geothermal system monitoring applications.

The geothermal heat pump (GHP) offers one of the most effective ways to save energy and cut carbon dioxide emissions from buildings. In fact, the U.S. Environmental Protection Agency (EPA) says this appliance stands as one of the most energy efficient and environmentally-benign of our heating, ventilation, and air conditioning options. Installing geothermal heat pumps to their full potential nationwide could cut by nearly half the amount of new power generation needed by 2030.

The numbers are impressive. Geothermal heat pumps would:

  • Avert construction of 91 GW to 105 GW of generation capacity, which is 42% to 48% of the 218 GW of new power the US will need in 2030
  • Save $33 to $38 billion annually in reduced utility bills

Yet installations of geothermal heat pumps remain relatively few. What’s the problem? The energy industry needs to do a better job making the case for this valuable technology. A US Department of Energy (DOE) report says that to grow the market, the industry needs to present more hard data and analysis on system performance.

Such data would serve two purposes. First, it would underscore the technology’s superiority to policy makers and consumers. Second, it would enable installers to maximize the potential of the technology.
