Abstract: A portable heating system used to heat a person while in cold environments. A heating unit containing a fuel combustion chamber and a heat exchanger oxidizes a fuel to produce heat. The heat from the oxidation process is transferred to the fluid using the heat exchanger. The fluid either boils or simply becomes less dense than cooler fluid in the heat exchanger and thus more buoyant. Convection moves the heated fluid upwards in to a thin bladder encapsulating the fluid and held against a person. The elevated kinetic energy in the bladder creates an entropy differential to the person. This differential allows the kinetic energy in the bladder to flow to the person thus warming them. The fluid now having less energy, now denser, flows back down the bladder to the heating unit by gravity.
