A vehicle cabin heating system of a vehicle, and methods of operation of such a heating system are provided. The vehicle cabin heating system scavenges waste heat from drivetrain components. A heat pump provides further heat scavenging for delivery to the vehicle cabin. A supplemental heater may be selectively activated to provide supplemental heating when operation of the heat pump and/or vehicle cabin heating system are inadequate to provide prompt heating response. The supplemental heater may, for example, be a positive temperature coefficient (PTC) heater positioned downstream of a heat pump heater and/or a heater core, and/or may include a positive high voltage coolant heater positioned within a coolant fluid circuit useable to heat coolant for delivery to the heater core and/or heat pump.
