Abstract
The implementation of the very low geothermal energy is not as extended as the rest of renewable energies. The high initial investment these systems usually require makes them unaffordable for most users. In this regard, this research tries to emphasize the importance of a suitable dimensioning of the whole geothermal plant. With that aim, three different calculation methods have been presented. One of them is based on manual calculations using standard values while the two remaining assumptions consider the use of specific geothermal software. Results reveal that the most suitable method is constituted by the implementation of optimized parameters in the geothermal software. These parameters are obtained from a series of previous analysis and laboratory tests. Applying the most appropriated procedure the initial investment is considerably reduced. Additionally, the electricity consumption of the heat pump is also lower using the mentioned calculation. In this way, the present research demonstrates that and adjusted and proper calculation process can make the geothermal system more attractive for a large number of users.
