ABSTRACT:
A portable fluid heating unit which may be used for supplying warm water to divers which includes a three stage heat exchange system wherein a fluid source, such as sea water, is initially heated as it passes through coils within the heating unit firebox and is subsequently heated in a first heat exchange chamber surrounding the firebox, after which, the fluid is heated by heat exchange with the exhaust gases from the firebox in a second heat exchange chamber. The temperature of the fluid is continuously regulated to insure that the heated fluid being conveyed to a diver is maintained at a substantially constant temperature.
