ABSTRACT:
A diver's gas heater, for use with a hot water heated suit, to heat the diver's breathing gas for added comfort in cold water. Hot water from a surface installed source is pumped through a hose to the diver's suit and the heater is installed directly in the hot water supply hose. The hot water passes through a tubular heat exchanger and the breathing gas flows through an annulus around the water conducting tube. A portion of the hot water is tapped off to maintain heating around the short length of breathing gas hose between the heat exchanger and the diver's helmet.
