Quick answer: Geothermal energy uses the stable temperature of the ground—around 10-18 °C throughout the year in Spain—to heat and cool buildings. A network of buried pipes collects this heat through a fluid, and a geothermal heat pump raises it to a useful temperature for heating, cooling and hot water. For every kWh of electricity

The pursuit of energy efficiency and lower monthly bills has led many townhouse owners to consider geothermal energy. However, one question keeps coming up: “My garden is very small—can I really install a vertical ground-loop system?” The short answer is yes. Thanks to vertical ground-loop technology and the compact size of today’s heat pumps, geothermal
Can you imagine enjoying a swim in 28°C water in April or late October without worrying about your electricity bill? In 2026, technology means we no longer have to depend on sunshine or expensive electric heaters. The answer is beneath your feet: geothermal pool heating. Thanks to the stable temperature of the ground, you can
When it comes to decarbonizing a home, the question is no longer whether to install a heat pump, but where to draw the energy from: the air or the ground? Although both technologies are pillars of the energy transition, their performance depends on a fundamental physical variable: the stability of the energy source. In this

Heating and cooling a detached home in Spain presents one of the greatest energy challenges for homeowners. Large floor areas, high ceilings, and the need to maintain comfort year-round can drive up energy consumption. However, there is a solution that combines sustainability, efficiency, and long-term savings: installing geothermal heat pumps alongside photovoltaic solar panels. In
Geothermal energy is becoming one of the most efficient solutions for heating and cooling homes and buildings in Spain. However, one of the key steps before installing a geothermal heat pump is deciding between a vertical and a horizontal system, as each has different technical, regulatory, and financial requirements. In this comprehensive guide, we examine
