Jones GeoThermal Systems

Also known as Geoexchange or "ground source heat pump" technology, these closed loop and open loop systems are the most energy efficient, environmentally clean, and cost-effective air conditioning HVAC systems available.

There Are 4 Basic Types of Geothermal Energy Sources

Closed loop systems circulate a water-based solution through a "loop" of small diameter, underground pipes. In cold weather this solution absorbs heat from the Earth and carries it to the geothermal unit, where the heat is amplified and delivered throughout your house. In warm weather the process is reversed - excess heat is carried from your home and deposited into the Earth, keeping you refreshingly cool during the hottest summer.

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 utilize ground water as a direct energy source. In ideal conditions, an open loop application can be the most economical type of geothermal system.

Benefits of GeoExchange

How does a GeoExchange system work?
Throughout the year, outdoor temperatures fluctuate with the changing seasons. However, underground temperatures do not. In fact, about four to six feet below the earth's surface, temperatures remain relatively constant year-round. A GeoExchange system, which consists of an indoor unit and a buried earth loop, capitalizes on these constant temperatures.

In the winter, fluid circulating through the system's earth loop absorbs stored heat and carries it indoors. The indoor unit compresses the heat to a higher temperature and distributes it throughout the building. In the summer, the system reverses, pulling heat from the building, carrying through the earth loop and despositing it in the cooler earth.

What makes a GeoExchange system different from conventional systems?
A GeoExchange system utilizes the energy from the sun, which is stored in the earth, to heat and cool homes and buildings. Typically, electric power is used only to operate the unit's fan, compressor and pump. So, unlike conventional systems, GeoExchange systems do not burn fossil fuel to generate heat--they simply transfer heat to and from the earth.

How efficient is a GeoExchange system?
A GeoExchange system is more than three times as efficient as the most efficient conventional system. Because GeoExchange systems do not burn combustible fuel to make heat, they provide three to four units of energy for every one unit used to power the system.

What does GeoExchange mean to the environment?
Because GeoExchange systems work with nature, not against it, they minimize the threats of acid rain, air pollution and the greenhouse effect. An environmentally friendly fluid is used in the closed, continuous loop.

Do GeoExchange systems require much maintenance?
No. In fact, GeoExchange systems are practically maintenance free. When installed properly, the buried loop will last for generations. And the other half of the operation--the unit's fan, compressor and pump--is housed indoors, protected from the harsh weather conditions. Usually, periodic checks and filter changes are the only required maintenance.
