Geotermia
It is power that can be obtained trough the advantage of the heat of the interior of the Earth. The heat of the interior of the Earth is produced for several factors, between which it is possible to emphasize the geothermal gradient. We must consider that between the 10 and 20 meters of depth the temperature is constant throughout the year, making the rounds between the 7 and 14 degrees, by each 100 meters of depth the temperature increases 3 degrees.
Since the temperature of work of the installation does not surpass 50º C, the degree of comfort of the house can be considered very high.
Geotermia is the most efficient solution from an economic perspective. The most important cost in power matter of the present houses, is the cost in air conditioning (heat and refrigeration) and in sanitary hot water. Geotermia solves a part very important of the power consumption of the houses, being able to get to save more of 70% of the power cost.
