Geothermal ground source heat pump with cooling and heating

How it works
There are three important elements to a ground source heat pump: 

1.The ground loop
This is comprised of lengths of pipe buried in the ground, either in a borehole or a horizontal trench. The pipe is usually a closed circuit and is filled with a mixture of water and antifreeze, which is pumped around the pipe absorbing heat from the ground. The ground loop can be:
•Vertical,  for use in boreholes
•Horizontal,  for use in trenches
•Pound/Lake installation 

3.Heat distribution system
This consists of under floor heating or radiators for space heating and in some cases water storage for hot water supply.
