A peltier is limited to always consuming more power then it has the ability to move. It is a direct heat pump, and also does not setup a differential that is impermeable (or even close ot that, heat moves back from the hotside to the coldside hurting efficiency). Phase can move many times its own input wattage by setting up a impermeable barrier (like walls and insulation), as well as trapping and releasing heat instead of moving it.
