With a heat pump, you need dual fuel in colder climates.
Either ng, lp or elect.
Elect is usually the most expensive yo operate.
And if not currently wired for it, you will need to run some pretty big wires.
If you are already using lp for other stuff, I'd keep it for emerg heat.
If no other appliances use lp, I'd still keep it for emerg heat.
My house has ng back up.
Would never consider replacing with elect heat strips.

^^^ This makes sense. I have a heat pump and a gas furnace. Thermostat switches from HP to gas based on run time. I generally just turn off the HP when we start gettin 20° temps. No heat strips for me.
