How a Heat Pump works ?

The principle is very similar to the operation of refrigeration and air
conditioning,
heating from the air (warmed by the sun).

The Heat Pump system constains a fan that forces air through an
evaporator (a). It contains very cold liquid refigerant. The heat in the
air that passes through this
evaporator os absorbed by the refrigerant.

The now warm gaseous refrigerant is then circulated in the system via
a compressor (b). As it goes through the compressor its pressure rises
and the temperature increases further. From here it travels to the
condenser (c), where the heat form what is now a super hot
refrigerant is transferred to the water supply tank. The cooled down
refrigerant then goes through an expansion valve, which reduces its
pressure cooling it further and the cycle starts again.
