Both work just as well. The only difference is what the supply voltage is at hand. Heaters are rated in watts. Your electric bill is rated in watts consumed per hour. Watts = Amps x Volts. An example, 500 watt heater at 120 volts will equal 4.16 amps. The same heater at 240 volts will equal 2.08 amps. As you can see if the voltage goes up the current goes down but the wattage total is always the same. That is the reason that you are billed on wattage, and not on what the service voltage or the current draw of the service is.
A 120-volt water heater should not be run over a 14-gauge wire at 300 feet. The voltage drop over such a long distance would be significant, potentially causing the water heater to not function properly or even become a safety hazard. It is recommended to use a larger gauge wire or locate the heater closer to the power source.
To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
For a 2500 watt water heater operating at 120 volts, you would need a 20 amp breaker. This ensures the breaker can handle the load without tripping.
To find the current in amps that a 750 watt, 120 volt heater draws, you can use the formula: Amps = Watts / Volts. So, 750 watts divided by 120 volts equals 6.25 amps. Therefore, the heater draws approximately 6.25 amps.
If V is the rated voltage of the equipment, and Vs is voltage of the supply, we have this approximate equation: Vs = 2 V. That is enough to wreck the equipment and/or blow the fuse.120 volt appliance on 240 voltsThis senerio will use an electric baseboard heater but the results will be the same for any electrical appliance.The heater will operate over its given specified wattage. A 120 volt heater run off of 240 volt will have an output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. A 240 volt heater can be run off of 120 volts but the wattage will be reduced.For example if an ordinary 1000 watt baseboard heater's supply is 120 volts, the current of the heater will be, I = W/E 1000/120 = 8.3 amps.The resistance of the heater is R = W/I (squared) =1000/8.3 x 8.3 (69) = 14.5 ohms.Applying 240 volts on the same heater whose resistance is 14.5 ohms results in a new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/14.5 = 3972 watts.This is 2972 watts, almost 300%, higher than the manufacturer's designed safety rating.The amperage drawn by connecting a 120 volt, 1000 watt heater to a 240 volt source will be, I = W/E = 3972/120 = 33 amps.W = watts, I = amperage, R = resistance in ohms and E = voltage.
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.

A typical 120 volt diesel engine block heater can pull around 1000-1500 watts, which would translate to approximately 8-12.5 amps. It's important to check the specifications of the specific block heater you are using to get an accurate measurement.
Yes, but by using 120 volts on the 208 volt element you will only be able to obtain 1/4 of the rated wattage from the element not 1/2 like it seems you should.
First find the current, I = W/E, 450/120 = 3.75 amps. R = E/I, 120/3.75 = 32 ohms.
You don't. The heater will operate over its given specified wattage. A 120 volt heater run off of 240 volt will have an output increase.

The recommended temperature to set a water heater is 120 degrees Fahrenheit.
