Neither. An electric heater's output or ability to make heat is rated in watts. If you buy a 120 volt, 1000 watt heater and a 240 volt, 1000 watt heater and compare them, they will cost you EXACTLY the same to run, and put out EXACTLY the same amount of heat.

∙ 9y agoNo, it costs the same no matter what voltage is used. The cost is based on the kilo wattage used per hour. The equation that best explains this is Watts = Amps x Volts. For example if there is a device that draws 1000 watts, it is the product of the amps drawn by the voltage needed to make the device operate. At 110 volts the amperage will be 1000/110 = 9.09 amps to equal 1000 watts. At 220 volts the amperage will be 1000/220 = 4.45 amps. At 480 volts the amperage will be 1000/480 = 2.08. As you can see both sides of the equation always balance. This is the reason you are billed on wattage use rather than what the amperage or voltage is because these values vary depending on what the manufacturer recommends to operate their equipment.

Why do you only have 110 power to your electric water heater?
There are small water heaters that run on 110 volts. However if yours is a large 240 volt heater and you only have 110 volts going to it, then it is fused and one on the fuses has blown in the service panel.
How many amperes use an electric heater?
The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps
Will a 110 electric heater produce the same amount of heat as a 220 heater at 1000 watts?
The load is a resistive load and as such it is governed by Ohm's law. Current is directly proportional to the voltage and inversely proportional to the resistance. As the voltage goes down so does the current. 2200 watt heater at 220 volts = 10 amps. R = E/I = 220/10 = 22 ohms of resistance in the heater. Now take the 2200 watt heater and using the same formula and at 110 volts. I = E/R, Amps = Volts / Resistance. 110/22 = 5 amps. As you can see ohm's law holds true, the current is inversely proportional to the resistance and as the voltage goes down so does the current. To answer the question, yes a 220 volt heater will run on a 110 volt circuit but at a reduced wattage. W = A x V = 5 x 110 = 550 watts.A 2200 watt heater at 220 volts would draw 1/2 the current of a 2200 watt heater at 110 volts.A 2200 watt heater at 220 volts is 22 ohms of resistance. Resistance would not change with the voltage, current would only be 5 amps (a resistor is a current limiter, it will only let more current through if you apply more voltage not less); but the wattage would only be 550 watts. This would only give you a fourth of the power this heater was designed for! The heater and the wires would have less heat.
How you check amp draw on compressor?
Divide the power rating (in watts) by the voltage (in volts). So if you use a 100 watt light bulb in a typical 110 volt lamp then it will draw 100/110 = .91 amps of current. Or plug a 1500 watt electric heater into a 110 volt wall socket and it will draw 1500/110 = 13.6 amps of current.
How do you determine electrical usage and efficiency on a portable space heater?
Electric heat is always 99% efficient. The only exception to this relates to 110 volt vs 220 volt, but this is based on myth.
What is more economical 110 or 220 electric baseboard heaters?
Not counting the equipment or installation cost, and assuming the cost of electricity is the same in either system, running cost depends on the power consumed. So check the wattage of the heater. Consider also that the heater may not be on all the time to maintain a temperature. If a heater has twice the power (not voltage) of another and is on for half the time it works out the same.
Ideal temperature setting for an electric water heater?
110-120 degrees Fahrenheit.
How much current will an electric heater draw from a 110-volt line if the resistance of the heater when hot is 26.7 ohm?
4.12A. V=IR

How do you convert 110 hot water heater to 240vert?
You don't, electric water heaters are not meant to be converted.
Is 230 volts or 110 volts more economical?
You buy power by the watt-hour. It has zero to do with the voltage!
What is the voltage of a small electric heater if the heater is drawing 12 amperes and has a resistance of 10 ohms?
Voltage is current times resistance, 1.2 x 110 = 132 volts.
What are the release dates for The Electric Company - 1971 110 1-110?
The Electric Company - 1971 110 1-110 was released on: USA: 24 March 1972

When installing either an electric or gas Hot water heater Do you have to install a mixing valve?
No mixing valve is needed for either one. Set water heater at desired temperature. Both are usually pre-set from factory at normal 110-120 deg.
