Geothermal Heating And Cooling Optimal In Residential, Commercial Applications
For new construction, or retrofitting, geothermal heating and cooling is the option of choice for high energy efficiency, system longevity, quiet operation, ease of maintenance and federal tax incentives.
Geothermal Heat Pumps
Geothermal heat pump systems (GHP) are unmatched for heating and cooling performance, reaching energy efficiencies of 600 percent. Like an air-source heat pump, a GHP moves heat instead of burning fuel to produce heat. It utilizes the constant temperature of the earth for efficient heat exchange. Generally, installation for GHPs are more expensive. However, the long-term payback is substantial, including energy savings, low maintenance and system longevity up to 20 years.
Geothermal heating and cooling encompasses a wide spectrum of uses. In addition to efficiently heating and cooling homes and buildings, GHPs are used for heating water for storage water heaters, and for heating pools and spas of any size, including your backyard pool or spa, or an Olympic-size pool at a community organization or school.
The type of installation design you choose for GHPs is dependent upon available land area, and the most cost-effective solution for the given project.
- Horizontal installation involves the most land area usage. This type of installation is popular for new home construction, or commercial construction that has substantial land area available.
- Vertical installation has the advantage of utilizing smaller land area. However, it is more costly than horizontal installation. Trenches are drilled very deep into the ground, perhaps as far as a few hundred feet for the vertical pipe loops.
- Horizontal hybrid design uses less land area than the horizontal installation, but goes deeper into the ground. The pipes are installed in a looping design (similar to a stretched phone cord). This design offers the benefit of lower installation costs than vertical installation, and not requiring the land mass that the horizontal design requires.
- Water-source GHPs are common in Florida, utilizing ground water, wells, ponds and lakes for the heating source.
