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