In EnergyPlus, there's a WaterHeater:HeatPump object.
Beware that this is a zonal object.
In the current OpenStudio public release (1.8.0) the object isn't accessible in the app, nor in the API as far as I can tell. So you would have to use an EnergyPlus measure (or take the out.idf and do it in the IDF editor).
The good news is that it was added recently, alongside a lot of other HVAC objects. You can download the OpenStudio 1.8.5 release candidate here.
