Coefficient Of Performance COP - Over Unity?

A heat pump with a COP of 2.4 will use a
kilowatt-hour of electricity to move 2.4 kilowatt-hourss of heat to the water,
making it "more than 100% efficient." Of course, the heat has to come from
somewhere, so the efficiency is still really less than 100%. It just looks like
it's greater because something else (not the heat pump's energy source) is
providing the heat pumped.
