Determining ground loop resistance with ground source heat pump monitoring data

A method comprising:

• operating, by a computing device, a heat pump that uses a ground loop to perform heating or cooling in a site;
• during the operating of the heat pump over a time period:
• measuring, by the computing device, a first series of measurements of a ground loop water flow rate by the heat pump;
• measuring, by the computing device, a second series of measurements of a ground loop fluid temperature for the heat pump;
• measuring, by the computing device, a third series of measurements of a local soil or deep earth temperature;
• and
• outputting, by the computing device to a remote location from the site, the first measurement, the second measurement, and the third measurement, wherein a ground loop thermal resistance value is calculated at the remote location for the heat pump based on the first measurement, the second measurement, and the third measurement, wherein:
• the ground loop thermal resistance value for the heat pump comprises a first ground loop thermal resistance value for a first heat pump that is installed at a first location, and
• the first ground loop thermal resistance value for the first heat pump is used to predict a second ground loop thermal resistance value for a second heat pump that is installed at a second location.

A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a computing device, cause the computing device to be operable for:

• during the operating of the heat pump over a time period:
• measuring a first series of measurements of a ground loop water flow rate by the heat pump;
• measuring a second series of measurements of a ground loop fluid temperature for the heat pump;
• measuring a third series of measurements of a local soil or deep earth temperature;
• and
• outputting to a remote location from the site, the first measurement, the second measurement, and the third measurement, wherein a ground loop thermal resistance value is calculated at the remote location for the heat pump based on the first measurement, the second measurement, and the third measurement, wherein:
• the ground loop thermal resistance value for the heat pump comprises a first ground loop thermal resistance value for a first heat pump that is installed at a first location, and
