I think Mike is exagerating. :-)

As I recall, you get about 20-25 deg C temperature difference from
one side of a Peltier junction device to the other side.  You can
stack them (multiple stages) for more.  Transferring the heat energy
is not free -- there's a not inconsequential current consumption.
