Advantages of Geothermal |
||||
A borehole is drilled to a depth of over 100 feet. |
PVC piping is fed into the borehole. |
* Cuts heating and cooling costs 25% to 50% * Increases comfort and control * Preserves home aesthetics and beauty of land * Simpler design, maintenance and operation * Environmentally friendly technology |

| Earth's natural heat is collected through the winter through a series of pipes, called loops, installed below the surface of the ground. Fluid circulating in the loop carries this heat to the home. An indoor geoexchange system then uses electrically-driven compressors and heat exchangers in a vapor compression cycle - the same principle employed in a refrigerator - to concentrate the Earth's energy and release it inside the home at a higher temperature. In typical systems, duct fans distribute the heat to various rooms. In the summer, the process is reversed in order to cool the home. |
