In general, yes. but what is important is to look at the SEER rating of the unit. The higher the number, the more efficient the unit. Also, consider the size of the room you are trying to cool and the average outside temp and humidity that the unit will be working against. You may only need a 5000 BTU unit or for a large room a 12 or 18K unit. I know, TMI.

∙ 12y agoAbsolutely not. Standard electric heaters (resistance heaters) are 100% efficient so the only difference is you can get more power from a 220 volt circuit. Power being watts. The highest watt heater on a 120 volt circuit is usually 1500w With 220 volts you can go higher. So, a 1500w heater on 120 volts will use the same amount of electricity as a 1500w heater on 240v

∙ 12y agoNO. you pay for electricity in watts. (actually watt-hours but we keep it simple for you.)
(W)watts are calculated as (A)amps times (V)volts.
so a 22,000 watt appliance uses
220 V x 100 A= 22000W
110 V x 200 A = 22000W
or:
22000 V x 1 A = 22000W
1 V x 22000 A = 22000W
you pay 22000 Watts no matter how many volts goes into the house.
think of this: What is heavier, 1KG of feathers or 1KG of lead?
neither, they both weigh the same.

∙ 15y agoNo, the amount of energy consumed is based on how much work you demand from the motor, not the voltage (110v or 220v).

∙ 14y agoless efficient than the 110 volt motor.because as the voltage is more so the loss will be more. therefore efficiency will be less.
Wiki User
∙ 9y agoNo. It just needs twice as much current (double the amps) to deliver
the same amount of power. So you would need heavier wire to run
a motor on 110 with the same power.

Can you use a 12 volt battery charger to heat water?
Yes it could be possible. There are two parameters that have to be met. You will need a 12 volt DC submersible heater. The wattage of the heater must be low enough so as not to draw more amperage than the battery charger's output can supply. The formula to use would be I = W/E. Amps = Watts/12. An example would be, for a 120 watt heater, A = 120/12 = 10 amps. If your battery charger has a higher output than 10 amp then you can make the battery charger heat water.
Wiring diagram electric baseboard heater?
Yes, the heater is a 240/120 heater, but I want to operate as 120 volt
What size breaker for a 1500 watt 120 volt heater?
15 amp
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.
Why is 240 volt electricity more dangerous than 12 volt electricity?
It is neither more or less dangerous . The determining danger factor is amperage.
What dose volt mean?
volt is a measurement of electricity
Can you use a 24VDC-100RPM motor as wind generator?
All DC Motors can generate electricity according to their size & input volt. 24 volt DC Motor is best for generate electricity. Even you can generate up to 24 volt AC. The big size of Motor is also depends to generate more ampere (current). Remember 24 volt DC Motor which have less RPM without gear is better & efficient for generate electricity than having the more RPM (Round Per Minute). So try it & generate electricity. (for further information, feel free to ask any thing regarding electricity, "admnpmiu_tariq@yahoo.com")
How much does 1 volt of electricity cost?
Electricity is not sold by the volt. It is sold by the watt, a unit of power. One watt equals one volt-ampere.
What is the answer to inch is to distance as volt is to?
electricity
If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?
Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous
How you can pass electricity 20 volt and 25 amp from converting 12 volt 1 amp adopter to 20 volt and 25 amp?
A 1-amp adaptor can not be used for equipment that draws more than 1 amp. It is not clear from the question which part of your system is 12 v and which is 20 v.
What yields a higher heat output a 2kw 277 volt electric heater or a 5 kw 230 volt electric heater'?

Are electric baseboard heaters efficient?
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts - but uses 12.5/6.3 amps
