Fuel pre-heating device

A fuel pre-heating device for increasing the fuel efficiency of a gas heater comprising:

• an orifice having a first end and second end, wherein said first end contains at least one recess and said second end contains at least one opening;
• a first and second cavity within said orifice;
• a tube having a first end and a second end, wherein each of said ends is attached to said second end of said orifice;
• and
• an air mixer surrounding said tube of said pre-heating device;
• wherein fuel enters said pre-heating device at said at least one recess, flows through said first cavity of said orifice and into said first end of said tube, flows through said tube and out of said second end of said tube into said second end of said orifice, where said fuel is forced through said second cavity of said orifice and out of said at least one opening of said orifice, wherein said fuel mixes with air inside said air mixer and ignites to form a flame;
• and
• wherein said flame envelopes the entirety of said tube and heats said fuel within said tube.

A method of increasing fuel efficiency in a gas heater comprising:

• attaching to said gas heater a fuel pre-heating device comprising:
• an orifice having a first end and second end, wherein said first end contains at least one recess and said second end contains at least one opening;
• a first and second cavity within said orifice;
• and
• a tube having a first end and a second end, wherein each of said ends is attached to said second end of said orifice;
• forcing fuel into said pre-heating device at said at least one recess;
• wherein said fuel flows through said first cavity of said orifice and into said first end of said tube, flows through said tube and out of said second end of said tube into said second end of said orifice, wherein said fuel is forced through said second cavity of said orifice and out of said at least one opening of said orifice, and wherein said fuel mixes with air to ignite and form a flame;
• and
• enveloping the entirety of said tube within said flame, thereby heating said fuel within said tube.
