I don’t know a lot about heat pumps, but one inefficiency that irritates me is that we are doing opposite things in isolation frequently. I want to cool the house (so have waste heat) but also want to warm my water, so make heat. In winter I warm my house, except for the fridge where it’s trying to cool its contents. If there was any overlap or coordination it would surely be possible to have less hardware, working smarter and using less power.
