[EnergyPlus_Support] Re: water to water heat pump

["aleph_venturini" <aleph.venturini@xxxxxxxxx>]

Hello! Did you eventually solve your problem with the GSHP?
I am trying to simulate both a cooling and a heating plant with ground-coupled water to water heat pumps, but I always get errors or the plant does not work.
I have tried the following:
- GroundHeatExchanger:Vertical
- GroundHeatExchanger:Pond
- HeatPump:WaterToWater:EquationFit:Heating & Cooling
- HeatPump:WaterToWater:ParameterEstimation:Cooling & Heating

in all cases I copy/pasted the GSHP objects from the E+ example files into my idf, but i cannot get a working simulation and I don't understand where the errors i get could come from.
I'd be very glad to know if someone of you did get some GSHP plant actually running... thanks

Alessandro
