Ground loops and a heat pump.
Geothermal energy heating and cooling systems.
As a heating and cooling system geothermal heat pumps can cut maintenance costs as there are fewer components that can break.
For example solar powered heating and cooling systems only collect energy during peak sunlight hours.
Geothermal is the only renewable that provides reliable operation 24 hours a day 7 days a week 365 days a year making it the reliable renewable by using the infinite energy source in the earth a geothermal heat pump operates efficiently and effectively all year round rain or shine day or night windy or not.
Geothermal energy is considered a renewable resource.
Geothermal heating is the direct use of geothermal energy for some heating applications.
Compared to other types of green energy systems geothermal provides steady production.
Growth in the geothermal heating and cooling market averages 12 annually as demand continues to rise for highly efficient hvac systems leveraging sustainable energy.
Today system pricing is more competitive than it was a decade ago because there are many more manufacturers selling ground source heating and cooling systems and there are more experienced installers competing.
A geothermal cooling and heating system has three main components.
In fact millions of ghp systems are already heating and cooling homes and businesses worldwide and that includes all 50 u s.
Deep and enhanced geothermal systems.
Approximately seventy countries made direct use of a total of 270 pj of geothermal heating in 2004.
This simple straightforward and convenient system can provide both heating and cooling which saves you money space and so many headaches.
Geothermal heat pumps can operate in any climate hot or cold because of the earth s constant underground temperature from 45 to 75 f depending on location.
Geothermal heat pumps can be used in any climate.
Ground source heat pumps and direct use geothermal technologies serve heating and cooling applications while deep and enhanced geothermal technologies generally take advantage of a much deeper higher temperature geothermal resource to generate electricity.
The heat pump unit the liquid heat exchange medium open or closed loop and the air delivery system ductwork and or the.
Humans have taken advantage of geothermal heat this way since the paleolithic era.
System life is estimated at up to 24 years for the inside components and 50 years for the ground loop.
At a minimum conventional heating and cooling require two distinctly different systems for different seasons.
Even though the installation price of a geothermal system can be several times that of an air source system of the same heating and cooling capacity the additional costs are returned to you in energy savings in 5 to 10 years.
As of 2007 28 gw of geothermal heating capacity is installed around the world satisfying 0 07 of global primary energy.
