For domestic use, 240V works just fine. This is because you are never usually too far from an outlet socket and it avoids lugging around a heavy transformer.
The reason it's 240V is because that's the power line that has been standardized over here. Some European countries use 220V, while some specify 230V; most appliances will accept 220-240V however. Regular appliances like lamps, laptops, and phones do not need access to this power.
A 240V outlet is common in many homes to provide electricity to appliances, such as hot water heaters and electric clothes dryers. Homeowners are often unsure of what size an outlet is, if their homes were built by someone else or the electrical work was done by another.
In North America, the terms 220V, 230V, and 240V all refer to the same system voltage level. With electrical loads, the voltage will drop, hence the common reference to voltages below 120 and 240, such as 110, 115, 220, and 230.
UK mains is 230 or 240v ac 50Hz. 50Hz means that the voltage cycles 50 times per second. For UK mains, the peak voltage is around 330v, and the overall ac waveform gives the same heating effect as 240v dc would. It is called 240v because it is equivalent to 240v dc for heating and lighting.
People use this electricity to power everyday items—such as domestic appliances, televisions and lamps—by plugging them into a wall outlet. The voltage and frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used.
RE: Using a 60hz mains device in the UKNow, the 220-> 230 vs 240 -> 230 V change is over. So even UK should be close to 230 V.
Europe. The official voltage for the rest of Europe (and including Great Britain) is 230 but most electrical goods operate at around the 220 – 240 volt mark. All of Europe operates on the same 2 round pronged outlets (except for Great Britain that operates on its own unique 3 pronged outlets.)
Locate the breaker in your electrical panel that is connected to your thermostat. If you see a single breaker switch like the one shown in the picture below, you likely have 120V. If you see a double breaker, like the pictures shown below, you likely have 240V.
Yup, that's right. The motor should run fine if the service line voltage is between 209 and 253.
If you have a single voltage device that accepts only 120V, then it will not operate in the UK without a converter or transformer. A converter is for use with “electrical†devices and a transformer is for use with “electronic†devices.
In the UK electricity is supplied as alternating current at a frequency of fifty cycles per second, or 50 hertz (Hz).
| How many Volts are: | Equivalence in Watts |

| 120 Volts | Equivalent to 1662.77 Watts |
| 127 Volts | 1759.76 Watts |
| 220 Volts | 3048.41 Watts |
| 240 Volts | 3325.54 Watts |
High (HV), Extra- High (EHV) & Ultra-High Voltages (UHV) - 115,000 to 1,100,000 VAC. Medium Voltage (MV) - 2,400 to 69,000 VAC. Low Voltage (LV) - 240 to 600 VAC.
Sometimes you may hear 110 volt plugs referred to as 120 volt. Do not be confused by this; think of them as one and the same. There are a few variations of the 110 volt outlet based on the size of the breaker associated with the circuit, which is measured in Amps. The 2 most common variations are 15 Amp and 20 Amp.
240V is most common for electrical appliances which require more power, such as a dryer, electric stove, or hot tub. There is no difference in efficiency in our heaters between 120V and 240V (or any other voltage). The reason why 240V is advantageous for appliances and heaters in a home has to do with amperage.
Once AC was widely accepted as being superior to DC for power distribution, 110V became the standard for AC distribution presumably because it used the "safer" Voltage level of the DC system. After metal filament lamps became feasible, 220V became common in Europe because of the lower distribution costs.
Thus, higher current can be more dangerous than higher voltage; however, since voltage and amperage are directly proportional (in conditions that offer the same resistance), 110v wiring is usually considered safer to work with because it uses fewer volts and as such can only carry half as much current as 220v wiring.
Only a handful use 60Hz. The standard in the United States is 120V and 60Hz AC electricity.

Plugging a 220v device into a 110v outlet is not recommended. If you did, it's highly likely that you'll damage or destroy the appliance. If your device has no motor, then it'll perform poorly, running on half the needed energy. If the device does have a motor, then the lower voltage can damage it.
The tools needed to convert an 120V wall outlet to a 240V outlet include screwdrivers, a neon voltage tester, and a black marker. You also need a 240V receptacle and a double-pole circuit breaker. Turn off the power at the main circuit breaker to avoid electrocution while you are working.
Yes, in the same but reverse way if you connect 120V appliances to 240V supply then insulation designed for 120V supply get damage under 240V supply.
The choice of 120V was to compensate for IR drop. The reason for 220-240 was that with AC distribution, this became a convenient voltage level to deliver to homes. And the reason why Europe dropped the 120V domestic distribution was simply economics. You can save on copper.
