Drilling


• A topographical diagram of the available terrain is executed, according to the project, for engineering the ground heat exchanger ;
• The first borehole is completed, at a depth between 50 and 120 m, depending on the project and/or other factors;
• The ground heat transfer measurements are conducted using special equipment made in the USA;
• The obtained data are transferred on the PC and using a dedicated software the correct size of the ground heat exchanger is established;
• The remaining boreholes are drilled;
