In very cold climates, having a hybrid system like the one you’re describing is that universal no brainer in my opinion. Especially since most cold regions also typically have really long transitional periods where your heat pump is most efficient and pays itself off fastest. Combining that with turning it off during harsh winter weeks gives you the best of both worlds.
It’s not even a no brainer even then. You absolutely need to actually do the math for your particular situation to make that determination. For me it works out. For my neighbor down the road who is a logger, it does not. He can harvest, process, and store 2 years worth of firewood in a mere handful of hours. Any other heat source makes little sense for him.

You really, really, really need to do the math!
