Geothermal heating and cooling systems can save you a lot more money than you may have expected, especially in the face of extreme weather like we've had this past summer.
Many Texans are breathing a sigh of relief after record heat waves, and we're looking forward to fall. Cooler weather may turn your mind to winter home improvements, and North Texas winters are nothing to sneeze at. Fortunately, our latitude and soil composition are perfect for the finest heating and cooling technology available today: geothermal systems.
Geothermal Heat Pumps (GHP) are 70 years ahead of the green movement. There are multiple system choices, the federal government provides tax credit incentives, most local utility companies offer rebates, and investment returns last the system’s life (25-50 years).
Quieter than conventional HVAC systems and not subject to carbon monoxide monitoring, geothermal heat pumps require less maintenance, most of them can supply hot water, the indoor precious metal components are not subject to theft, and geothermal energy is a natural and clean resource.
Geothermal systems, especially ground-loop, are ideal for the North Texas-Dallas metropolitan areas. If you’re interested in taking advantage of a geothermal system, here are three systems to consider:
Closed-Loop Piping Systems
Horizontal: most cost-effective installation; can be used on small lots; trenches dug about four feet deep; layout of piping done one of three ways:
- Two pipes buried, one at six feet, other at four feet; or
- Two pipes buried side-by-side in two-foot-wide trenches five feet deep; or
- Slinky Method: looping pipeline buried in shorter trench; used for unconventional installations.
Vertical: most cost-effective installation where soil is too shallow for trenching or existing flora must remain undisturbed:
- Two four-inch diameter wells drilled 100 to 400 feet deep placed 20 feet apart.
- Each well receives one U-bend bottom-looped pipe; pipe tops join horizontal manifold pipe connected to indoor heat pump.
Open-Loop Piping System
Aquifer/Pond/Lake: Water, primary heat exchange fluid, comes from well or easily accessible body of water. Upon completion of water cycling through the geothermal piping, water returns to well, recharge well, or as surface groundwater discharge, as long as the discharge method meets local codes and regulations.
