A fuel pre-heating device for use with gas heaters to increase fuel efficiency including an orifice and a pre-heat tube. Fuel enters the device through the orifice and travels through the preheat tube and back to the orifice where it is then expelled and mixed with air to ignite into a flame that envelopes the entire pre-heat tube and heats the fuel within the tube to a very high temperature. Any air mixer known to those skilled in the art can be used with the heating tube. A heat conductor can also be used with the pre-heat tube. The pre-heating device can be easily added to standard heaters, is small in configuration, and inexpensive to manufacture. The small size of the heating tube allows for immediate preheating of the fuel, which is used by the heater in the same heating cycle, thereby yielding a more efficient preheat. This preheating system prevents the fuel from being wasted.
