Good info.

So I suppose maths go like this:

P=power, U=voltage, I=current, R=resistance

P=U*I -> I=P/U -> 1500W / 220V = 6,82A
R=U/I -> R = 220V / 6,82A = 32,26 Ohm (max. resistance I assume, for that voltage)

then, if we use 96V instead of 220V
I=U/R -> 96V / 32,26 Ohm = 2,98A
P=U*I -> 96V * 2,98A = 286W

Oh. For 220V element and 110V operating voltage power would be 375W, 1/4 of full power.

But then. 1500W 110V element with 96V:

R -> ~8 Ohm
P -> 1150W

Much better. One element produces more power than two 220V put in paraller. Two units provide twice power if put paraller.
