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.
What else can I help you with?
Can a 120 volt water heater work over a 14 gauge wire at 300 feet?
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.
What size breaker for a 1500 watt 120 volt heater?
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.
What size breaker for 120 volt 2500 watt water heater?
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.
How many amps does a 750 watt 120 volt heater draw?
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.
What will happen if 120 volt appliance is plugged into 220 volt outlet explain with electrical equation?
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.
Can i run a 240 volt water heater on 120 volt?
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.
How do you know if you have a 120 or a 240 volt baseboard heater?
To determine if you have a 120 or a 240 volt baseboard heater, check the electrical specifications on the heater itself, often found on a label or plate. Additionally, you can inspect the wiring: a 120 volt heater typically has a single wire and a ground, while a 240 volt heater usually has two hot wires and possibly a ground. If you're unsure, you can also use a multimeter to measure the voltage at the heater's terminal; a reading of around 120 volts indicates a 120 volt heater, while around 240 volts indicates a 240 volt heater. Always ensure safety precautions are taken when handling electrical components.
Can a 120 volt water heater work over a 14 gauge wire at 300 feet?

How many amp breaker for a 2500 watt 120 volt 19 gallon water heater?
To determine the appropriate breaker size for a 2500-watt, 120-volt water heater, you first calculate the current using the formula: Current (Amps) = Power (Watts) / Voltage (Volts). For a 2500-watt heater at 120 volts, the current is approximately 20.83 amps. It's common practice to use a breaker rated at 125% of the continuous load, so a 25-amp breaker would be suitable for this application to ensure safe operation.
Can a 208 volt hot water heater be used with 110 volt with a 20 amp fuse?
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.
