I have often wondered about heat pumps and would like to clarify.  I
assume a reverse cycle aircon (or even a single cycle) uses or is a
heat pump.

I also assume that I can *move* more heat energy into a room than the
energy I use to move the energy.  Is this correct.  If so then I will
think of it like getting a large container of hot coals and moving
them into a room.  I use less energy to move them than the coals are
giving off in heat.

Is the analogy anywhere near correct.

Another assumption I will make is that I can not say the same for
removing heat from a room using a heat pump.  Ie I must use as much
energy to cool a room as the energy I am removing.  Is this correct.
