A water heater that supplies a constant demand for hot water is a negative impedance load. The higher the average voltage, the less average current it will consume. Of course, in practice, when the voltage gets too high, the heater may burn out or crack due to thermal fatigue, or the thermostat contacts will weld together since the instantaneous current is much higher, even though the average current is lower. | |
