The fulfillment of a heat requirement is achieved not with a drilling very deep but with more perforations with a maximum depth of 150 m.
The design of a probe system requires you to consider a number of factors that affect the efficiency of the geothermal system.
Depending on the space available, it is necessary to study the geometry of the system of probes so as to give them a distance mutual sufficient to prevent the thermal interference between a probe and the other: the range is variable between 4 8 m and also according to the conductivity of the soil.
Even in respect of the mutual distances is always advisable not to exceed the number of probes, on small surfaces, in order to avoid significant thermal variations of the ground.
The geothermal field has to be designed for optimize the consumption of electrical energy needed to pump the water of the wells.
Once realized the geothermal field and grouped the probes, the expected completion of the final hydraulic connection.
In order for the the circuit result balanced in each probe you can opt for a system of connection and distribution collectors e control valves or with connection system circuit with offset so that the circuits are self-balancing.
