What is an aquifer?
Using a borehole ground source heat pumps can extract heat energy from the groundwater stored in an aquifer, an underground layer of water-bearing permeable rock.
Open and closed boreholes:
Closed loop boreholes
Closed loop boreholes can be used for aquifer heat sources.
The principle of a closed loop borehole is that at no point does the fluid in the borehole leave the system, it is continually cycled through the closed system.Read More
Open loop boreholes
Open loop boreholes can also be used for aquifer heat sources.Read More
