2. General definition of geothermal energy The two different installation setup : - Horizontal - Vertical Drawbacks of the installation - Home setup - For geothermal plant Disadvantage of functioning of Heat pump and his price 3. Geothermal energy ( this name comes from geo, meaning earth, and thermal, meaning heat from the Earth) . It's clean and sustainable. You cant get much greener than a geothermal heating and cooling system. Steam rising from the Nesjavellir Geothermal Power Station in Iceland. 4. There are three types of installations : 1. Pond/Lake 2. Horizontal 3. Vertical These are closed loop installation. But open loops installation exists too, 5. A VIDEO SYNTHESIS FOR DIFFERENT TYPE OF INSTALLATION 6. The vertical pump sensors require drilling, therefore cost, and time of installation too long Being up steam at 250 C, can affect the surrounding vegetation. Installing more complex than a traditional heating. The horizontal pump sensors requires a surface available in your green space or garden of 1.5 to 2 times the size of your building. Both require with the highest quality installation. only with low temperature radiators FOR HOME SETUP 7. Low production Being up steam at 250 C, can affect the surrounding vegetation. Water collected in the basement can contain chemicals, so it must be re- injected into the ground. Increase risk of earthquake FOR GEOTHERMAL PLANT CONCLUSION Geothermal energy is a renewable energy and always available. However, it is still not widely used because it has many drawbacks. 8. Heat pumps use a refrigerant fluid. harmful to EARTH. Bacteria present in the deposits, increase the corrosion. Pump source of pollution. We cant carry the geothermal energy in form of vapor. in the form of water or heat sulfur odor released. 9. Three types of heat pump Heat pump air / water Heat pump air / air Pump Water / heat Important:Yourchoicealsodependsontheclimateinyourarea,thesurfaceofthepartsofyour home,numberofoccupantsandtheconfigurationofyourexistingheating(radiators,boiler...). 10. The most expensive Prices from: 10,000 to 18,000 for water heat pump (horizontal sensors ) 15,000 to 20,000 for a vertical water heat pump sensors (with one or more boreholes) + 11.
