When operating a high efficiency nat gas forced air furnace and heat pump at what cost ratio or percent of gas therms to kilowatt hours does it make more sense to use the high efficiency furnace only?

There are 3413 btu per kWh and 100,000 btu per therm of natural gas, these are constants. In order to give a correct answer the exact efficiency rating of the high efficiency furnace and the energy costs per kWh and therms would need to be known.
