Modelling a ground-source heat pump with underfloor heating and cooling [EnergyPlus]
Hi!
I am trying to model a heating and cooling systems that uses a ground-source loop and then a water-to-water heatpump to be used in an underfloor heating and cooling system (the same tubes are used, just in a different mode). This has probably been done, but I can't seem to find the appropriate water-to-water heatpump.
I am looking at combining ZoneHVAC:LowTempRadiant:VariableFlow with a WaterHeater:HeatPump:EIR:(Heating/Cooling), but I don't see how I would use the same system for both heating and cooling? I am pretty new to modelling my own systems with custom nodes, pipes and so on, so forgive me the basic question.
Thanks in advance for your answers!

@Gijs_WE what simulation tool are you using? Please mention it in the title or body of your post, as well as add a tag so that others can provide better help. It sounds like you're using EnergyPlus based on the object types that you've mentioned.
Also, if you can upload your model to Google Drive, Dropbox, etc. and then share a URL for others to download, that would help others provide better solutions.
