This video explains in 3 minutes the basic principles of a Ground Source Heat Pump (GSHP), and how it is able to extract usable heat even when the weather is cold.
It highlights the year-round stability of ground temperature, and shows a closed-loop system with horizontal and vertical ground loop configurations.
A simple comparison of GSHPs with electric and gas heating systems is included, based on an anticipated SPF of 3.
