Two identical heaters each marked 1000w
Web2. If your heating element is a dumb resistor then: I = V/R. Thus the same resistor will draw 2x the current on 240V versus 120V. It's the same resistor, so the value of R does not change. Since. P = V*I = V^2/R. it will also burn 4x the power on 240V versus 120V. So you can use a 240V heater on 120V, it will just heat 4x less.
