How does it work? The geothermal energy It is the energy stored in the form of heat below the surface of the earth.
This heat contained in the subsoil is used through the use of geothermal heat pumps to heat in winter, cool in summer and supply hot water. Therefore, it gives or extracts heat from the earth depending on whether we want to obtain cooling or heating, through a circuit buried in the subsoil through which a solution of water with glycol circulates.
It is a Inexhaustible source of energy the 365 days of the year 24 hours per day, and unlike other systems, the weather conditions of the moment (sun, wind, etc.) do not influence.
It is an energy considered clean, renewable and highly efficient, applicable both in large buildings, hospitals, factories, offices, in homes and even in buildings already built.
Geothermal energy is capable of supplying up to 100% of the heating and domestic hot water (DHW) needs of a home, building, etc., even with very low outside temperatures, also providing cooling in summer, all with the same installation, through underfloor heating or fan coils.
This energy is respectful with the the environment and it has zero environmental impact, since the heat exchangers are located on the ground or in the foundations of the buildings themselves.
Sweden was the first European country to use geothermal energy, as a consequence of the 1979 oil crisis . In other countries such as Finland, the United States, Japan, Germany, the Netherlands and France, geothermal energy is a well-known energy that has been implemented for decades.
Geothermal applications depend on the characteristics of each source. High temperature geothermal resources (above 100-150ºC) are mainly used for electricity production . When the reservoir temperature is not sufficient to produce electrical energy, its main applications are thermal in the industrial, services and residential sectors. Thus, in the case of temperatures below 100ºC, it can be used directly or through a geothermal heat pump (heating and cooling). Finally, when it comes to resources with very low temperatures (below 25ºC), the possibilities of use are the air conditioning and obtaining hot water.
Geothermal Heat Pump (BCG)
Geothermal Heat Pumps are highly efficient and do not depend on changes in temperature and humidity of the air throughout the day or the seasons.
They are connected to exchangers that remain practically stable and constant in temperature and humidity all year round.
Aerothermal heat pumps, unlike conventional air-to-water heat pumps, are designed and built for maximum energy from outside air in very severe climatic conditions, both in winter and summer.
Thanks to the oversizing of its components, they are able to capture more energy from the outside. They also have a specially designed compressor that allows reach working temperatures above 60ºC
The development of geothermal heat pumps make it possible for them to be an alternative to conventional heating systems. Given these, the installation and start-up process is simpler and safer and the maintenance requirements of this type of equipment are very low.
Heating and Cooling with the same system?
In winter the house is heated by giving cold to the ground and in summer it cools by giving the heat to the ground, always with the same installation at no added cost
And why not also heat the pool? you can raise your pool a few degrees and gain comfort.
