Circulation: The above-ground heat pump moves water or another fluid through a series of buried pipes or ground loops. Heat absorption: As the fluid passes through the ground loop, it absorbs heat from the warmer soil, rock, or ground water around it. Heat exchange and use: The heated fluid returns to the building where it used for useful purposes, such as space or water heating.

Circulator pump - Wikipedia

A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system (as opposed to lifting a fluid from a point of lower potential .
