A Complete Guide to Energy from Beneath the Ground"},"content":{"rendered":"\n

Geothermal energy<\/strong> has established itself as one of the most stable, efficient and sustainable renewable energy sources available today. If you are wondering how geothermal energy works<\/strong> to heat and cool your home or business, this technology not only harnesses the earth\u2019s inexhaustible heat but can also significantly increase your energy savings<\/sup><\/sup><\/sup><\/sup>.<\/p>\n\n\n\n

Unlike other systems that depend on outdoor weather conditions, geothermal energy takes advantage of a fundamental constant: the temperature below ground remains stable throughout the year, regardless of the season<\/sup><\/sup>.<\/p>\n\n\n\n

What is geothermal energy, and how does it actually work?<\/h2>\n\n\n\n

Geothermal energy involves extracting heat from beneath the earth\u2019s surface to make our homes comfortable<\/sup><\/sup>. Based on water-to-water heat pumps, this system can deliver four to five times the electrical energy it consumes as thermal energy, achieving a coefficient of performance (COP) of 4 to 5<\/sup><\/sup><\/sup><\/sup>.<\/p>\n\n\n\n

The process has three main stages:<\/p>\n\n\n\n

1. Energy capture<\/h3>\n\n\n\n

The process begins with geothermal boreholes or buried collectors. A heat transfer fluid flows through them and absorbs heat from the ground, whose temperature remains constant throughout the year<\/sup>.<\/p>\n\n\n\n

2. Heat exchange and amplification<\/h3>\n\n\n\n

The captured energy reaches the geothermal heat pump<\/strong>, where a thermodynamic cycle raises its temperature and makes the heat available to the building\u2019s distribution system (underfloor heating, radiators or fan coils)<\/sup><\/sup><\/sup><\/sup>.<\/p>\n\n\n\n

3. Distribution and control<\/h3>\n\n\n\n

Thanks to the heat pumps\u2019 advanced technology<\/sup>, the following can be managed simultaneously:<\/p>\n\n\n\n
