Geothermal heating is a method that uses the natural heat from the Earth to warm buildings. This heat comes from the Earth's core and can be accessed through wells or underground pipes. By transferring this heat into homes, geothermal systems provide an efficient and eco-friendly way to maintain comfortable indoor temperatures. In addition to heating, geothermal systems can also cool buildings in the summer. They work by reversing the process, pulling heat from the indoor air and transferring it back into the ground. This sustainable energy source is becoming increasingly popular as people seek alternatives to traditional heating methods, reducing reliance on fossil fuels and lowering energy bills.
