    10 -15 kW would suffice

        I think the estimate of 10-15Kw is a little high. I'd look in the 8-10kw range, but use the calculator......

            I can but you need to supply a couple of parameters:

            starting temperature
            target temperature
            element watts

            program returns heat-up time based on these variables.

            Example for a 2x2x5 oven, starting at 80 degrees and heating to 400 with 5170 watts(23 amps) of heating elements takes 10 minutes and 19 secs to reach 400.

            If you increase the element size to 10000 watts(42 amps) it would reduce the heat up time to 5 min 20 secs.

              10-15kW isn't too high. it would enable that size oven to reach cure temp twice as fast as a 7.5kw oven which would also work, albeit with a little more complicated wiring scheme.
