If you know a little bit about how a geothermal heat pump works to provide comfort for a home, you’ll know that the loops that carry the refrigerant (a mix of water and antifreeze) need sufficient space in order to work correctly.

How much space do I need for geothermal?
There isn’t a simple answer to this, because geothermal systems can use a variety of loop configurations, and homes have different heating needs based on their size and their insulation level. The condition of the soil and the landscape will also affect the amount of space necessary.
The most common loop configuration is horizontal, where the loops lay out approximately 6–10 feet below the frost line. This is the most space-consuming configuration, but also one of the most effective and low-cost; if you have sufficient room from horizontal loops, this is the best option. Horizontal loops usually need 400–600 feet of loops for each ton of heating necessary for your home. An average sized home uses a 3-ton unit, and would need 1200–1800 feet of loops.
If you lack space for horizontal loops, geothermal drilling can put the loops in a vertical configuration, which buries them much deeper. This takes longer to install and costs more, but it will work well for smaller properties. Because the temperature is more stable at the depth the vertical loops are placed, the loops can be shorter.
When it comes to the space necessary to install a geothermal system in your home, the short answer is: We don’t know… yet. But it is easy to find out.
