Geothermal energy is derived from the heat of the Earth's core. It is clean, abundant, and reliable. It also supplies a renewable and sustainable source of energy. There are three primary applications of geothermal energy: electricity generation, direct use of heat, and ground-source heat pumps. Ground-source heat pumps used for geothermal heating and cooling require just one piece of equipment to move heat energy to and from the earth to heat and cool your indoor environment. Compared to ordinary systems, they can save you up to 60 percent on your monthly energy bills. Equally impressive is the fact that geothermal energy is an unlimited resource. And it's literally right there in your own backyard. The lot surrounding a suburban home or other building contains a vast reservoir of low-temperature thermal energy - typically 10 times that required over an entire heating season. The sun, the surrounding earth and the heat rejected while cooling during the summer, constantly resupplies this resource. A geothermal system uses the Earth's thermal properties in conjunction with electricity to provide unprecedented efficiency. For every unit of electricity the system uses, it provides four units of heating energy, giving a geothermal system a 400 percent efficiency rating, on average. These numbers can translate into real savings on your utility bills year-round.
The earth loop transfers heat to and from the ground - eliminating the need for fossil fuels. It's the heart of a geothermal system, and the biggest advantage over ordinary technologies. Earth loops come in two basic types. Closed loops, made of durable, high-density polyethylene (IPS) pipe, are buried in the earth or submerged in a lake or pond. They transfer heat by circulating a solution of water and environmentally safe antifreeze. Open loops use ground water pumped from a well as a heat source. Which type to use depends on the terrain, the cost of trenching or drilling, the availability of quality ground water and the availability of land.
|Horizontal Loops are used where adequate land is available. One or more trenches are dug from 100 to 400 feet depending on unit size and soil conditions. Polyethylene (IPS) pipes are inserted, connected to a header with supply and return pipes leading to the home and the trenches are backfilled. |
|Pond Loops can be installed if an adequately sized body of water is close to the home. A series of coils are placed on the bottom of the pond, connected by a header with supply and return pipes leading to the home through ground trenches. |
|Vertical Loops are installed where space is limited. Holes are bored 75 to 300 feet deep using a drilling rig, the pipe is inserted, and the holes are filled. The pipes are then connected horizontally a few feet below the surface to a header with supply and return pipes leading to the home. |
|Open Loops are used where there is an abundant supply of quality well water. The well must have enough capacity to provide adequate flow for both domestic use and the geothermal unit. |
Why Geothermal Heating & Cooling?
Warranties: All geothermal equipment and loop installations come with outstanding manufacturer warranties.
- Lower Operating Costs: Operates more efficiently than ordinary heating and cooling systems, saving 30 to 60 percent in most cases.
- Efficiency: 400 percent overall efficiency, meaning the system produces four units of energy for every unit spent, compared to traditional 90 percent efficient gas furnaces or other less efficient equipment.
- Safe & Clean: No flame, no flue, no odors, and no danger of fire or carbon monoxide. High efficiency air cleaners remove dust and pollen to improve indoor air quality.
- Flexible: Heating, cooling, and domestic hot water - three systems from the same completely self-contained indoor unit, no noisy, unsightly outside condensing unit.
- Economical Water Heating: Water heating can be a significant energy expense. A geothermal system can reduce the high cost of water heating by as much as 66 percent.
- Quiet Operation: High-efficiency compressors, soft-start variable speed blowers, and flex connections on ductwork make operation exceptionally quiet.
- Comfortable: Zone systems provide precise distribution of air throughout the year instead of uneven temperatures experienced with ordinary furnaces in winter, also provides superior cooling and dehumidification in summer.
- Dependable: Microprocessor controls and state-of-the-art components mean smooth operation and years of virtually maintenance-free service.
- Environmentally Friendly: The system emits no carbon dioxide, carbon monoxide, or other greenhouse gasses, which are considered to be major contributions to environmental air pollution.
- Value: Installing a geothermal system adds value to your home and increases the marketability of your home.
