Vertical Geothermal Ground Loops:
Vertical loops are the best and sometimes the only geo choice if you have: limited space,
rocky terrains, extreme temperatures, or retrofits. These are more expensive than
horizontal loops. The good news isit uses less pipe, and it is a more stable system,
because the underground temperature is more constant at deeper depths. . Thank
goodness for an area of earth not intensely heated by the magma layer of the earth or the
outdoor temperature. A drilling rig is used to bore 150 to 300 foot deep holes in to the
ground. After which, pipe is looped into the whole and grouted. A typical system requires
300 to 600 feet of piping per ton of heating and cooling.
