Gas in the rebreather loop will lose heat to the surrounding water, but the temperature of loop gas will always be higher than the water, while open circuit scuba gas will always be colder than the water due to adiabatic cooling in the regulator stages. Open circuit gas is warmed by the surrounding water. [38]
