Geothermal heat pumps continue to gain popularity as an environmentally-friendly alternative to conventional forced-air HVAC systems. Geothermal technology provides extraordinary efficiency since it maximizes the heat exchange process. While geothermal equipment can help lower your utility bills, it’s important to hire a contractor who understands the challenges of installing, repairing and maintaining these complex systems.

How Geothermal Works

Traditional air-to-air heat pumps experience a substantial loss of efficiency when they’re exposed to extreme summer and winter temperatures. However, geothermal HVAC systems use the earth as the medium for energy transfer, which creates a more efficient exchange because the ground temperature is relatively stable all year round.

To fully understand geothermal systems, it’s important to isolate the three basic components that differentiate geothermal from conventional heat pumps:

  • Condensing Unit: The condensing unit contains the condensing coil, compressor and the other components needed to complete the refrigeration cycle.
  • The Conduit: The conduit is the primary pathway between the condensing coil and the ground, which facilitates the transfer of energy.
  • Distribution Network: For proper distribution of conditioned air, the system incorporates an evaporator coil and air handler.

In many respects, a geothermal heat pump operates in the same manner as an air-source heat pump. The geothermal process is distinguished by a specially designed loop-style heat exchanger. Much like a conventional heat pump, a geothermal system can be configured to provide radiant heating, air conditioning and forced-air heating.

The innovative heat exchange equipment is attached to the earth through a specially engineered polyethylene piping network. There are two main configurations, including closed and open loop systems. A closed loop system relies on an antifreeze solution circulated through a piping grid while an open loop system uses an available water source. Based on convenience and reliability, closed loop systems have become more popular in the past few years.

Geothermal Benefits

Ground source heat pumps offer many benefits when compared to forced-air heating and cooling systems. In North Texas, temperatures can vary by over 60 degrees between the lows of winter and the highs of summer. By contrast, the ground temperature barely changes at all below the frost line. This consistent temperature stability is the main reason a geothermal HVAC system can save as much as 40 percent on heating and cooling costs when compared to a typical 13-SEER air source heat pump. In addition to better efficiency, the reduced number of operating cycles helps to lower repair costs and can extend the lifecycle of the equipment.

Geothermal systems appeal to environmentally-conscious people due to the low emissions associated with the technology. The EPA has endorsed geothermal technology since it has the lowest CO2 emissions in the HVAC industry.
