So, does this overlooked technology make Ohm's law obsolete? Why can't you
calculate the energy usage? You know the resistance of the heating elements
and the amount of time you need to achieve the temperature rise in the
furnace and the line-in voltage. What else do you need?

I'm building what I believe will be a super high efficiency electric
furnace utilizing engineering technology overlooked by studio glass
makers. But I need a method to prove my energy usage so I can present
my findings. Besides thorough documentation of my charge and idle
cycles, I need a meter that will work with a phase-angle SCR. I'm not
familiar with any device that can monitor my usage through an SCR. With
an inductive ammeter, one would need a constant graph since current
draw flucuates wildly from moment to moment. Any usenet folks out there
have any ideas?
