Definition: Girning is a type of geothermal heat exchanger used in the construction industry to transfer heat from one location to another. It works by generating heat through the movement of water, which then flows through a series of pipes and valves into the heat exchanger. The heat exchange allows for the transfer of thermal energy between two locations or systems, reducing the need for traditional heating systems that rely on electrical power. The term "girning" comes from the Greek word "girannos
