Energy 101: Geothermal Heat Pumps

The following edit was recommended by DOE’s Office of Energy Efficiency and Renewable Energy’s Geothermal Technologies Office: At :58, “During the winter, the air is usually cooler than the temperature below ground. The solution circulates in a loop underground and absorbs the Earth’s heat. This heat is brought to the surface and transferred to a heat pump. T̶h̶e̶ ̶h̶e̶a̶t̶ ̶p̶u̶m̶p̶ ̶w̶a̶r̶m̶s̶ ̶t̶h̶e̶ ̶a̶i̶r̶ ̶a̶n̶d̶ ̶y̶o̶u̶r̶ ̶r̶e̶g̶u̶l̶a̶r̶ ̶h̶e̶a̶t̶i̶n̶g̶ ̶s̶y̶s̶t̶e̶m̶ ̶w̶a̶r̶m̶s̶ ̶t̶h̶e̶ ̶a̶i̶r̶ ̶s̶o̶m̶e̶ ̶m̶o̶r̶e̶ ̶t̶o̶ ̶a̶ ̶c̶o̶m̶f̶o̶r̶t̶a̶b̶l̶e̶ ̶t̶e̶m̶p̶e̶r̶a̶t̶u̶r̶e̶.̶ ̶F̶i̶n̶a̶l̶l̶y̶ Ducts circulate the air to the various rooms.”

An energy-efficient heating and cooling alternative, the geothermal heat pump system moves heat from the ground to a building (or from a building to the ground) through a series of flexible pipe “loops” containing water.

  1. If every Gov implemented a carbon tax for ppl using non-renewable energy, it'll force everyone to use renewable-energy systems like this. Saves money and good for the environment and good capitalist competition for non-renewable companies.

  2. Great video. Hope OSHA don't see the guys in the trenches with no sloping, shoring, or trench boxes being used….

  3. Поздрави на американските ни колеги от Геосолар В-63 българският производител на качествени термопомпи.Very good clip!!!

  4. Would have been nice had the DOE ref'd the church specifics (and got the facts right).  It is the Holy Cross Lutheran Church in Wheat Ridge, CO.  The narrator also screwed up on the ground loop, it is not a horizontal loop but is vertical (drilled); consists of 28 boreholes that are 400' deep under the parking lot. We did not have enough space for a horizontal or pit loop.  System has been up and running since 2009 with very low utility bills.  Major Geothermal designed it, Major Heating installed the mechanical system and designed the controls, and Major Geothermal did the functional testing.

  5. To be particular about it: Yes, it is formally called geothermal energy. But no, it's not really geothermal, but solar energy you use. With the ground as a heat storage. If the system would depend on the heat-replenishment from the interior of the earth, it would not work, because it's too less heat flow.

  6. This is a ground source heat pump not a 'geothermal heat pump'. Geothermal energy is from the earths core- i.e. volcanoes etc. Iceland uses lots of geothermal energy- because it can!

  7. In what city do you live, so we know what climate you are in? And what style of system do you have–horizontal or vertical and buried at what depths? Thank you for the comment, Mr. Marlow. To anyone who posts later about their results of installing and using a geothermal system, please include the answers to my questions just asked.
