Borehole heat exchanger

A borehole heat exchanger is a system used to transfer heat between the ground and a building for heating or cooling purposes. It involves drilling deep holes into the earth and inserting pipes through which a fluid circulates. Because the ground maintains a relatively consistent temperature throughout the year, this setup efficiently captures heat in winter or rejects heat in summer. The system connects to a heat pump, which then distributes the warmed or cooled air or water into the building. Borehole heat exchangers are an energy-efficient, sustainable way to regulate indoor temperature using renewable ground sources.
