Saying that all appliances turn energy to heat is true, but saying that all appliances do is turn energy in to heat is not. While heat is still a byproduct, lots of appliances make things move as well.
They’re really moving refrigerant. It’s just that the refrigerant keeps changing temperature (heating up at one end of the journey and cooling down at the other end).
More specifically, we force it to undergo phase changes under different pressures, and in doing so it absorbs/releases latent heat in the air. It’s converting latent heat to sensible heat.
I understand that, and called it out in my comment. Heat being a byproduct of movement does not mean that a device that creates movement “only” creates heat. That’s like saying all drink dispensers only dispense piss, because what does it eventually turn in to?

For heat pumps, the thing they’re moving is heat.

And what is that movent? Eventually decays into heat.
