A hot-water heating system for use by submarines, divers and the like in an underwater environment includes a heating-medium circuit and a hot-water circuit. The heating-medium circuit includes an electric-motor-driven compressor in a water-tight submersible housing for compressing a heating-medium fluid. The heating-medium circuit also includes a condenser heat exchanger, a throttle valve, and an evaporator heat exchanger connected in series between a discharge outlet and a suction inlet of the compressor. The evaporator heat exchanger can make thermal contact with water surrounding the water-tight housing to absorb heat from the water and the condenser heat exchanger make thermal contact with the water in the hot water circuit to transfer heat to the water.
