A ground heat pump uses energy from the ground for heating. It is efficient, but requires a lot of space for installation. The heat generated in the lower heat source is transported to the upper source and distributed around the building. Within the lower source, you can choose a horizontal or vertical collector. A horizontal collector is installed at a depth of approx. 1.5 m below the ground frost zone, but this requires a large plot area. On the other hand, a vertical collector requires drilling to a depth of up to 100 m.
