I'm working with OpenStudio SketchUp Plugin, to generate the IDF associated to a building.

I already added a VRF HVAC to the building; now, I'd like to add a "MICRORAPID T 1000-V0" (a compact electric fan heater) to a room (thermal zone).

Which is the best way to model it inside the IDF?

I thought about ZoneHVAC:Baseboard:Convective:Electric, but I'm not sure.

If it is essentially just a fan and a heating coil, then you should use the ZoneHVAC:UnitHeater object in EnergyPlus. This object is an example of a compact object -- one object in the IDF that is built from multiple other objects (fan and heating coil, in this case) also in the IDF that it needs to reference.

Ah, thank you for the hint! The datasheet is this..I think it's just a fan and a heating coil, so ZoneHVAC:UnitHeater could fit this heater.

That technical sheet doesn't do a great job showing the internal components, but it does mention a fan and heating coil, so I believe this is the right approach.
