What is geothermal energy all about?
A geothermal system is a heating and cooling unit designed to extract the natural heat stored in the ground during the winter and discharge heat from air conditioning to the relatively cool ground in the summer. A geothermal system can also heat water. The sun shining on the earth warms the ground to maintain a relatively constant temperature of about 52 degrees fahrenheit year round in northeast Ohio at a depth of 4 to 6 feet.
Heat is extracted from the earth during the winter or heat is discharged to the earth during the summer air conditioning season by a vertical earth loop heat exchanger. 4" diameter bore holes about 150 feet deep are Nudist CampsNudist PicturesAmateur Girls drilled into the ground. Two lengths of 3/4" plastic pipe with a U bend on the bottom are inserted into the bore hole. The hole is sealed with bentonite clay to prevent surface water contamination of ground water and to provide a good earth bond to the pipe. One 150´ bore is drilled for each ton of heating capacity. A water solution is circulated through the pipes to exchange heat between the earth and the geothermal unit. A small pump circulates the solution through the pipes and the heat exchanger within the geothermal unit. After the pipes are installed below the surface, there is no visible sign of the earth loop.
The geothermal unit within the home looks similar to any other conventional heating and cooling system. Since heat removed from the home during the summer is discharged to the circulating loop solution, there is no outside condensing unit as required for other air conditioning systems.
A geothermal system is the most economical heating and cooling system available today. Because it uses free energy from the earth, its efficiency ratings are from 300% to 400%. Both the USEPA and US Department of Energy have endorsed geothermal systems as having the least environmental impact and the lowest energy consumption.
Geothermal energy systems result in a 30% to 70% operating cost reduction when compared with alternate heating and cooling systems. Geothermal systems cost more to install than other heating and cooling systems primarily because of the need to install the closed loop which is the energy source. When a geothermal system is installed in a new home the higher installation cost is more than offset by the lower operating cost so that the homeowner is left with more spendable money every month. In addition to the lower monthly operating costs, and lack of an outside condensing unit, there is no concern for carbon monoxide or fire. A geothermal unit provides a uniform comfortable temperature throughout the home.
Grace Geothermal, Inc. has been installing geothermal systems exclusively for 20 years in northeast Ohio. We are the leading company in northeast Ohio having installed nearly 1000 systems including the Lake County YMCA Dream Homes for the past five years. |
Benefits of investing in a GeoThermal Comfort System
- Lower operating costs - Operates more efficiently than ordinary heating and air conditioning systems, saving up to 80% in most cases.
- Safe and clean - No flame, no flue, no odors, and no danger of fire or carbon monoxide. High efficiency filters remove dust and pollens to improve indoor air quality
- Quiet operation - A super efficient compressor and soft-start, variable-speed fan make the Premier line so quiet that many people find themselves checking to make sure the system is actually on.
- Comfortable - Provides precise distribution of warmer air in winter. Gone are the uneven temperatures experienced with ordinary furnaces. In the summer you get central air conditioning with better dehumidification.
- Flexible - Heating, central air conditioning and domestic hot water -- three systems: all from the same compact unit.
- Environmentally Friendly - The system emits no carbon dioxide, carbon monoxide, or other greenhouse gasses which are considered to be major contributors to environmental air pollution.
- Attractive - The completely self contained unit is maintained indoors. There is no need for noisy, unsightly, outside condensing equipment.
- Reliable - Microprocessor controls and state-of-the-art components allow smooth operation and years of maintenance-free service.
