The needs of your home, its area, the surrounding area, and its geological character define the form and choice of your geo exchanger.
According to the above, the geothermal systems are as follows:
A horizontal system, in which a water - glycol mixture circulates and is placed at a shallow depth (closed circuit), where there are no temperature changes due to weather conditions, covering a surface twice the square meters we want to heat.
A vertical system is placed at a greater depth (closed circuit) when the external space is not sufficient to create a horizontal network. In this case, pairs of pipes are installed which are sunk into a borehole of 60-100 meters to capture the energy required for the heating and cooling operation.
Open system, which exploits the temperature of the underground water, pumping water and returning it to the same aquifer.
