Unless of course you have a heat pump (or an A/C with a reversing valve, which is the same thing). Which by all means please use that instead. You’re not going to top a heat pump in terms of efficiency. We’re talking 300% efficient heat production minimum. Best you can hope for with electric heating is 100%.
It’s also about the same electric-to-thermal efficiency as a regular space heater, so if that’s how you heat, there’s no reason not to.
