Generally, the higher voltage (240 volt cook top) is preferred, as higher voltage is more efficient. Use correspondingly sized pots and pans and you will enjoy best results. It may be best to order the cooktop for which you have power readily available. For example, if you are replacing another electric cooktop, it is probably best to order the same voltage, as you may already have the proper wiring in place. To make the best choice, you may want to ask a licensed electrician in your area, which electric cooktop / voltage would be best for your application (show them the chart that is directly above this paragraph).

Boil Times for 1 Quart of Water: based on initial water temperature: 58-62 degrees Fahrenheit (data provided by Kenyon & may not be applicable to other brands).

Note: for best transfer of heat, your pot or pan must be appropriately sized relevant to the diameter of the burner.  The 6.5 inch, 1200 watt, 120 volt burner actually can make water boil faster than the 8 inch, 1400 watt, 120 volt burner, presumably due to more BTU being directed towards fewer square inches of surface area at the point of heat transfer, as well as less metal in the pot/pan to absorb heat. 240 volts is often stated to be more efficient, but as you can see above, it can be much slower to produce results, especially in the (smaller) 1200 watt burner elements.
