Heating coil and Re-heat coil do not normally used together.
A fan coil unit may have an auxiliary heating element in the terminal for use during season change over period, especially in the two pipe fan-coil system.
(example FanCoilVAV:Reheat) This is where the word re-heat coil may not be so good.
In my Condo., when the heating is off at the end of Spring, before the cooling comes on in Summer, the heater provide heating at unusual cold nights.
For humidity control, the re-heat coil may be installed upstream at the AHU, during the cooling period.
The heater for use with heat pump in Winter is called the supplementary heater in EPlus. There are crankcase heater and sump heater as well, for the compressor.

Subject: Re: [EnergyPlus_Support] problem about reheat coil and heating coil
"Reheat coil" (kind of a bad name) is simply a heating coil in a
terminal unit. Its action
affects a single thermal zone. A "heating coil" is in the central air
duct and affects all of the supply
air. It is upstream from the reheat coils. The "reheat coil" is
controlled by the zone thermostat.
The "heating coil" is controlled by the supply air temperature setpoin
and the heating coil controller.
