It is a clean and renewable energy that uses the heat from underground to heat and get hot water in an environmentally friendly way. Depending on whether you want to get heating or cooling, you have to remove or transfer heat from the earth, through a set of collectors buried in the ground by circulating a water-glycol solution. To cool a building in summer, the geothermal system transfers heat over the interior of the building into the ground, while to heat a building in winter would be done the reverse, extracting heat from the ground for transmission to the building through the collectors.
The cost of maintaining this system is minimal, and its lifetime is over 30 years.
Average savings in electricity bill is 75%.
A geothermal climate control unit has:
– Geothermal pump which performs the energy use from the underground.
– Exchanger introduced into the subsurface. Is formed by a set of collectors of polyethylene of high strength and great life buried in the ground by circulating a solution of water and glycol.
– A hydraulic pump, which pumps the water-glycol solution flowing through the collectors.
In Klima Gaucín S.L. we installed two types of feedback systems:
This type of system comprises one or more circuits composed of a collector of high density polyethylene in the garden and buried at 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 it does not emit greenhouse gases. It is only viable for large surfaces.
It is the most recommended system, and also the less economical in terms of installation, but we must keep in mind that between 10 to 20 meters deep, the temperature remains constant throughout the year, hovering between 10 ° C and 15 ° C, and for every 100 meters deep the temperature rises 3 degrees Celsius by the geothermal gradient. As horizontally, is formed by a closed circuit through which circulates the water-glycol solution from the geothermal well to the pump and back continuously. This method is more efficient tan the horizontal.
