Convection deep fat fryer heating system

A convection oil fryer, the fryer comprising:

• a vat for cooking oil, the vat having a first end and a second end opposite the first end;
• a continuous tube having an inlet port at a first end of the tube, an outlet port at a second end of the tube, an inner coil portion and an outer coil portion, and a plurality of external radial fins spaced apart along a length thereof;
• and a burner in operative communication with a fuel line, wherein the burner has a longitudinal axis that is in a vertical orientation, wherein the inner coil section wraps around the burner in a vertical direction and the outer coil section wraps around the inner coil section in the vertical direction, so that the burner is centered inside the inner coil section and the inner coil section is between the outer coil section and the burner, the heating system further comprising a containment structure having a closed bottom end and a flue opening at an upper end, wherein the containment structure encloses the inner coil section, the outer coil section, and the burner, wherein the containment structure is positioned above the inlet port and the outlet port;
• and a pump circulating cooking oil from the first end of the vat to the inlet port of the continuous tube and from the outlet of the continuous tube to the second end of the vat in a continuous loop, wherein the burner heats the continuous tube to evenly transfer heat to the cooking oil while the cooking oil flows through the continuous tube from the inlet port to the outlet port so that heated cooking oil circulates back.
