GEOTERMIA: Natural energy, environmental and economic.
Geothermal is a very low cost way to heat and cool homes across Europe, the alternative to electricity and oil.
The sun's rays warm the earth's crust, especially in summer. As the land has a high thermal inertia, is able to store this heat, and keep even seasonally. In the basement, from about 5 meters deep geological materials remain at a constant temperature cloths wrapped throughout the year.
In the Spanish case, to a depth greater than 5 meters, the soil temperature, regardless of season or weather, is about 15 º C. Between 15 and 20 feet deep, thermal stability is about 17 º C all year round.
A geothermal system uses solar heat pump and a system of holes in the ground to take this temperate climate. The key to the efficiency of these heat pumps is the difference between the temperature is to be achieved and the temperature at which the item is heated.

Closed vertical sensor
Is the capture geothermal most recommended, it is also the least expensive but we must bear in mind that between 10 to 20 meters deep, the temperature remains constant throughout the year, hovering between 10 º C and 15 º C, and for every 100 meters the temperature rises 3 degrees Celsius by the geothermal gradient. Like the horizontal tubes is formed by a closed circuit through which circulates the water solution glycone from the geothermal well to the pump and back continuously. -
Ventajas económicas
This type of sensor consists of one or more circuits composed of a collector of high density polyethylene and buried in the garden to a depth of 1.5 m. This collector encloses a water-glycol solution suitable and compatible with nature and respectful of the ozone layer (without freon) and which emits no greenhouse gases.
-
Ventajas económicas
- Average saving of 70% in electricity bills.
- Geothermal energy is a renewable energy eligible for the administration and funding agencies of the geothermal installation.
- The maintenance cost is minimal, and its lifetime is over 30 years.
- By not produce combustion (no flame), easy installation in hazardous and special places such as monuments and art centers.
-
Ventajas para la salud
- Is a biomedical system because it eliminates the risk of transmission of legionnaires' disease in the absence of cooling towers.
- No toxic chemicals are used.
- Does not produce flames, so that can be installed indoors with minimal ventilation.
-
Ventajas medioambientales
- It uses natural energy from the sun and soil.
- Reducing CO2 emissions by around 50%.
- System is completely silent.
- Use the natural energy stored in the ground as heat
- Reducing emissions of NO and SO2
- Be combined with other renewable energies.
- No produced volatile pollutants particles.
-
Ventajas arquitectonicas
- Improved aesthetics in the building having no visible external elements in facades and roofs.
- Save space on rooftops and terraces
- Installation is identical to any boiler on the market.
- Spaces reduction techniques.
-
Otras ventajas
- Obtaining heating, cooling and hot water with one system
- Operating 24 hours a day, 365 days a year regardless of climatic conditions, which depend on other renewable energies.
- It is an inexhaustible source of renewable energy.
- No need for external supplies.
- You do not need costly maintenance.
- Can be controlled by computer.
