The Multiple Segments Gas Water Heater with Water Jacket is an invention to increase, by several times, the efficiency of a gas water heater presently used in homes. This device prevents energy loss of hot air escaping to the atmosphere, coming from combustion of fuel. This is fulfilled by increasing heat exchange surface area in the heater by segmentation of the water tank and by preheating the cold water in the water jacket placed around the segmented water tank composed of multiple heat exchanger segments.
