Thanl you so much @chris I think that I will wait for the next ThermalNetwork release as I plan to subdivide my network into different subnetworks, each with one GHE that can work independently.
On the other hand, I have some doubts about converting the GHE block to system_params, about the temperature setpoints that are ultimately exported to Modelica, and also about the possibility of having a water-to-water heat pump in the ETS not only for active heating and hot water but also for active cooling. It seems that when exporting to Modelica, there is a heat pump with a COP of 4 for SHW and a COP of 2.3 for Heating, and for Cooling it does a kind of free cooling at 18 degrees supply temperature. I’ll put it in the following post: GHE system_params
