Types of Geothermal HVAC Systems

There are several basic types of ground loop (geothermal) HVAC systems. Horizontal, vertical, and pond/lake are closed-loop systems. Another option is called open-loop. Any of these systems are appropriate for either residential and commercial building applications.


Horizontal Installation

generally most cost-effective for residential installations, particularly for new construction where sufficient land is available.

It requires trenches at least four feet deep. The most common layouts either use two pipes: one buried at six feet and the other at four feet or two pipes placed side-by-side at five feet in the ground in a two-foot wide trench.

The Slinky™ method of looping pipe allows more pipe in a shorter trench. It cuts down on installation costs and makes horizontal installation possible in areas it would not be with conventional horizontal applications.


Vertical Installation

Large commercial buildings and schools often use vertical geothermal systems because the land area required for horizontal loops would be prohibitive.

Vertical loops are also used where the soil is too shallow for trenching, and they minimize the disturbance to existing landscaping.

A vertical system’s holes (approximately four inches in diameter) are drilled about 20 feet apart and 100 to 400 feet deep. Two pipes fit into these holes that are connected at the bottom with a U-bend to form a loop.

The vertical loops are connected with horizontal pipe (i.e., manifold), placed in trenches, and connected to the heat pump in the building.


Open-Loop System

This type of geothermal system uses well or surface body water as the heat exchange fluid that circulates directly through the GHP system.

Once it has circulated through the system, the water returns to the ground through the well, a recharge well, or surface discharge.

This option is practical only where there is an adequate supply of relatively clean water, all local codes and regulations regarding groundwater discharge are met.


Hybrid Systems

Hybrid geothermal systems using several different geothermal resources, or a combination of a geothermal resource with outdoor air (a cooling tower) are another technology option.

Hybrid approaches are particularly effective where cooling needs are significantly larger than heating needs. Where local geology permits, the “standing column well” is another option.

In this variation of an open-loop system, one or more deep vertical wells are drilled. Water is drawn from the bottom of a standing column and returned to the top.

During periods of peak heating and cooling, the system can bleed a portion of the return water rather than re-injecting it all, causing water inflow to the column from the surrounding aquifer.

The bleed cycle cools the column during heat rejection, heats it during heat extraction, and reduces the required bore depth.
