To be clear (as mud), the furnace only uses LP and 12v - but - if you have a heat pump in a 15k AC, you will have 'Elec Heat' on the thermostat. If set to 'Elec Heat', the heat pump works until the temp goes below 40F or the temp drops more than 5 degrees difference from the temp setting, then the gas furnace kicks in.
