Okay, but hear me out. If you reverse it, you'll have a heat pump oven that also cools your house. 🤓

    a heat pump oven sounds like an actually cool idea. why is it not a thing yet?

    The difference between oven temperature and room temperature is too high for it to be efficient. Like, a fridge is maybe cooling things 30F (~15C) maybe 50 (~25) for the freezer. An oven goes to like 500F 260C, so it would have to maintain a heat differential of like 430 (~215) degrees. Like, it’s just less efficient than a resistive coil at that point.
