Plus Plus, while the unit can only be in heating or cooling mode (so no heating one room while cooling another)
Some manufacturers are actually working to change that. It’s just a heat pump. Meaning it moves heat from one place to another. That’s how they can be over 100% efficient, because they’re not using power to generate heat; They’re just moving the existing heat around. And that can absolutely include moving heat from one interior room to another.
I’m looking into installing two of these here (southern Europe). There are some models that reach an SCOP of 5. That means that in heating mode for every Kw used they release 5Kw of heat in the room. They are legally considered renewable energy.
