Understanding Ground Source Heating Systems

Ground source heating systems work by exploiting the thermal mass from rocks and soil below ground and using this energy to provide sustainable heating and cooling for buildings on the site. For open-loop ground source energy systems, groundwater is abstracted at ambient temperature from the ground, passed through a heat exchanger before being re-injected back into the ground, usually requiring at least one pair of boreholes. To operate successfully, open loop ground source systems require a comprehensive understanding and expertise in many different areas including:
