The large heat pumps would harness heat from sources
The most cost-effective option for residential applications is called closed loop horizontal installation. In this type of installation, plastic pipe is laid in horizontal air conditioner at least four feet deep. The pipes can be installed straight or in loops resembling a big Slinkly - this requires deeper but shorter trenches, which can help in smaller yards. For a typical home, you might have to install 1,000 - 2,000 feet of tubing/piping, so this isn’t a small project!
A second option is called the closed loop vertical system, in which u-shaped sections of pipe are installed in borings drilled 150+ feet deep. These systems are more expensive because of the drilling costs, but they can be used in tighter places or where the soil is very rocky or difficult to dig in. Vertical systems have been employed in areas as densely populated as New York City.
A final common option is referred to as an open loop system. Here the heat exchange is done via groundwater withdrawn from a well rather than through a closed loop of piping. Heat is transferred from the water to the building via the heat pump , and then the water is reinjected into the groundwater aquifer via a second well some distance away. This can be the easiest approach from a technical standpoint (and can work in dense urban areas as well), but it can introduce some permitting hassles in areas where groundwater is used for drinking or is tightly regulated.
There are some other options (such as using a lake or pond as your heat source), but the three above are the most common options in most residential situations. There are also some interesting innovations in the technology of the heat pump equipment itself (such as using the waste heat for hot water, hooking the heat pump up to in-floor radiant heating systems, and other higher-tech approaches), but we’ll cover those in a separate posting.
Clearly, finding a contractor skilled in this type of system is critical! We have a directory of geothermal heat pump installers around the country here. If you don’t find any in your area, then check out the installer lists provided by some of the top heat pump manufacturers :
* WaterFurnace;
* ECONAR installers;
* FHP Manufacturing;
* Earthlinked Technologies.
Oh, one more thing to note. A geothermal heat pump is NOT the same as geothermal heating, where you heat your house directly using hot water pulled from deep underground. There aren’t that many parts of the country with the necessary underground geothermal energy to do this (primarily in the West), and even in these places almost all systems are commercial-scale operations. So if you’re thinking of harnessing the earth’s energy for your heating / cooling needs, most likely a geothermal heat pump is the way to go!
