With the use of heat pumps geothermal heating and cooling systems extract heat energy and transfer it into buildings saving you approximately 50 to 60 on heating and cooling costs depending on the fuel to which you are comparing. 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. Step 1 use the home s basement. Geothermal energy is considered a renewable resource.

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. Approximately seventy countries made direct use of a total of 270 pj of geothermal heating in 2004. In summer months geothermal cooling functions in a similar way to standard air conditioning only heat is not. A geothermal heat pump ghp or ground source heat pump gshp is a central heating and or cooling system that transfers heat to or from the ground.

Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the paleolithic era. Growth in the geothermal heating and cooling market averages 12 annually as demand continues to rise for highly efficient hvac systems leveraging sustainable energy. Deep and enhanced geothermal systems.

The heat pump unit the liquid heat exchange medium open or closed loop and the air delivery system ductwork and or the. In fact millions of ghp systems are already heating and cooling homes and businesses worldwide and that includes all 50 u s. 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. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational.

Climatemaster geothermal systems are hands down the most efficient and comfortable heating and cooling systems available today for your home or business. It uses the earth all the time without any intermittency as a heat source in the winter or a heat sink in the summer. Utilizing the earth s natural energy it s free and climatemaster systems make it available to you saving money providing years of comfort all while reducing your dependency on fossil fuels. As of 2007 28 gw of geothermal heating capacity is installed around the world satisfying 0 07 of global primary energy.

A geothermal cooling and heating system has three main components. Geothermal cooling systems can be complex or very simple. The major components of a geothermal heating and cooling system are buried and they often have warranties of up to 50 years. Inside the home the heat pump unit has a lifecycle of up to 25 years making this one of the most long lasting systems on the market.
