A:Answer Hey there, thanks for reaching out to us. The 120 volt and 240 volt Advantium ovens both offer the same great cooking options. The primary difference is in the speed and interior light function. The 240 volt Advantium offers the following: 1) 4x-8x faster than conventional cooking. 2) Can have multiple heat functions on at once: microwave, fan, upper heat, lower heat, interior lights, etc. Ex. During Speedcooking, the microwave and upper and/or lower lamps can be on at the same time while cooking. 3) Interior light is the halogen cooking lights, so light does not stay on; cycles on/off with the cooking. 4) No preheat necessary, except with convection cooking. 5) Not approved for under-counter installation. The 120 volt Advantium offers the following: 1) 2x-4x faster than conventional cooking. 2) Heat functions cycle one at a time: microwave, fan, upper heat, lower heat, lights, etc. Ex. During Speedcooking, the microwave, upper lamps and lower lamps cycle on at different times. 3) Has a separate light for the interior light; light stays on. 4) Preheating is recommended. 5) Approved for under-counter installation. We hope this is useful information to you and we're wishing you the best. - Guy@GEA
