A solar hot water and recovery system includes a water loop, a refrigerant loop and a solar loop. Cross-heat exchange occurs in a first heat exchanger between the heat transfer mediums of the refrigerant loop and the solar loop to produce a super-heated fluid stream which is returned to the air conditioning or heat pump unit.
