AKA groun source heat pump. Heat pumps are interesting in that they can put out more energy in heat than they consume in electricity. The reason is because it is not producing the heat, just moving it from one place to another. Most heat pumps are "air source". So they have limitations in very cold weather. Ground source solves that issue.
