# @!group CoilHeatingGas
# Updates the efficiency of some gas heating coils per the prototype assumptions.
# Sets heating coils inside PSZ-AC systems to 78% efficiency per the older vintages.
# @todo Refactor: remove inconsistency in logic; all coils should be lower efficiency
#
# @param coil_heating_gas [OpenStudio::Model::CoilHeatingGas] a gas heating coil
# @return [Bool] returns true if successful, false if not
def coil_heating_gas_apply_prototype_efficiency(coil_heating_gas)
# Only modify coils in PSZ-AC units
