### Is there a way to Model a Vertical Helical shallow GSHP (Please Refer Fig.)for a residential building in EnergyPlus ? I have already tried Ground Heat Exchanger: Vertical Properties by utilizing G-function values from my analysis

I am trying to model a Veertical Helical shallow GSHP which utilizes helical vertical tube heat exchanger in Ground instead of a U-tube ground heat exchanger.

Until now, I have utilized the Foundation:Kiva to get ground temperatures (instead of undisturbed ground temperatures) and also modeled "Coil:Cooling: WaterToAirHeatPump: EquationFit", "Coil:Heating: WaterToAirHeatPump: EquationFit" and "AirLoopHVAC:UnitaryHeatPump: WaterToAir" with the GroundHeatExchanger: System. This system gives me a result but my intention of research is different

My main confusion is that GroundHeatExchanger: System models a vertical U-tube heat exchanger with a distance between two pipes and there is no other object which will help me define helical vertical tube. I want to model a helical vertical GSHP ( Configuration similar to figure and not slinky GSHP), can EnergyPlus model that ? I have read the Input/output references as well as the engineering references but could not find anything that can help

Any help or input will be appreciated.

Thanks, Archan.
