If you're trying to compare the caloric content of two forms of energy, knowing what you can get out of the energy by itself is helpful.
In the end, the HP will be up to 30% more efficient than strip heat (in my case the crossover point is under 10f where strip heat is cheaper to operate).
I built a breakdown chart showing cost per kWh for both heat pump and strip heat, then added gas to it as a comparison.
