Advantage

At the heart of a geothermal system are one or more ground source heat pumps, which operate in a manner similar to a common refrigerator. Unlike conventional heating systems that burn fossil fuels or use electricity to create heat, heat pumps simply move heat from one place to another.  The ground and lakes around us represent a vast reservoir of renewable thermal energy stored from the sun. This geothermal energy is estimated to exceed all other energy sources combined by more than two thousand times. At depths below 8 to 10 feet (2.5 to 3 meters), the earths temperature remains at or near the average annual air temperature above. During the winter, a geothermal system collects this low-grade thermal energy from the earth and concentrates it inside the house or building to provide space heating. For every unit of energy used by a ground source heat pump, a well-designed geothermal system can provide three to four units of heat energy to the building. All ground source heat pumps are rated by an industry standard called the Coefficient of Performance, or COP, which typically range from 3.0 to 4.0. This represents efficiencies of 300% to 400%.  In the summer, the process is reversed and the heat pump moves heat from the building and stores it back in the ground. Alternatively, the heat removed from the building can be used to efficiently heat a swimming pool, domestic hot water, or other parts of the building that require heat.

• Horizontal loops are often considered when adequate land surface is available. Pipes are placed in trenches, in lengths that range from 100 to 400 feet. Vertical loops are the ideal choice when available land surface is limited. Drilling equipment is used to bore small-diameter holes from 75 to 300 feet deep.

• Pond (lake) loops are very economical to install when a body of water is available, because excavation costs are virtually eliminated. Coils of pipe are simply placed on the bottom of the pond or lake. Open loop systems are the fourth type and utilize ground water as a direct energy source. In ideal conditions, an open loop application can be the most economical type of geothermal system.

• For efficiency upgrades where large geothermal systems are not viable, existing boiler/tower jobs are frequently retrofitted. Hybrid systems incorporate both geothermal loop coupled with down-sized conventional heat rejection or addition equipment (boiler or tower).

Some of the benefits of owning a geothermal system are:

• Efficiency — geothermal systems use the earths thermal properties in conjunction with electricity to provide unmatched efficiency. For every unit of electricity the system uses, it provides three to four units of heating energy - an efficiency of 300% to 500%.

• Lower Operating Costs — Because geothermal systems operate more efficiently than ordinary heating and air conditioning systems, annual operating cost are 30% to 60% lower in most cases. Geothermal systems can also supplement or provide all the heat needed for domestic hot water, hot tubs, and swimming pools - saving even more money

• Environmentally Friendly — Geothermal systems eliminate the combustion of fossil fuels on site and dramatically lower the need to generate power - reducing the emission of greenhouse gasses and the environmental damage associated with nonrenewable resource extraction

• Comfort — Because geothermal systems use the relatively stable temperature of the earth as an energy source, you are assured of constant, even heating in winter, and better humidity control in the summer. Geothermal systems eliminate the need for exhaust venting, reducing the number of penetrations in the building envelope and improving weather tightness

• Safety — No flame, no flue, no odors, no risk from carbon monoxide. Just safe, reliable operation year after year

• Flexibility — Ground source heat pumps can provide any combination of forced-air heating, radiant in-floor heating, domestic hot water, and air conditioning all from the same unit. From houses to office buildings to community swimming pools, and everything in between, geothermal systems can be designed to provide efficient heating and cooling solutions

• Quiet — The completely self-contained, indoor equipment does not need a noisy, unsightly outside condensing unit. Geothermal systems are quiet and discrete. Other than the lower energy bills, you will hardly know they are there.
