WebFeb 15, 2024 · The 3800-watt heating element can be wired with a smaller 12-gauge wire and a 20-amp circuit breaker. An electric tankless water heater can vary from 120 to 240 volts depending on the size and type. Under sink point-of-use (POS) electric on-demand water heaters use a 120-volt circuit with a 20-amp breaker. WebIf 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.
