Can 240V kettle be used in N. Am 115V ?
 
Looking at purchasing a unit that heats water with the usual immersed coil-thingy, but it is designed to be used in the Middle East on 240 V service. Seller says it has been used in the U.S. with an adapter.
Does such and adapter really exist? I can't imagine it would permit full heating power. Adapters surely work the other way around...permitting 115V appliances to be usde on stepped down on 240V service?
Thanks.

There are adapters, though it will likely take twice as long to heat the water.

i would check with the manufacturer and see if 115 volt heating element is available for the unit. pictures would help. why not run it on 240?

Or run a new dedacated line and breaker to run just that.

I needed space in my panel box, so I ran a 240 baseboard heater on 120v. It got warm, which was all I needed.

I am sure there are step up transformers available, but they would cost more than a 120v kettle and probably require more than a 20a outlet.

Why buy one that doesn't work without jury rigging it?

Look for one that is already wired for 110---

Am I missing something here?

I do not think your missing anything, it just sounds like someone who does not how these work and how bad an idea it is.
If the O/P could tell us what there really trying to do with this thing I'm sure someone could come up with a better safe way to do it.

I had a 240v compressor that I had to find power for on jobs. I had a short extension cord adapter that went to dryer or electric stove outlet.

Just read that again. You have to check one other thing. Many countries use a different cycle too. I know Germany used to use 50 cycle 220 volt.

It is also most likely a single wire 240 unit and not a 2 wire 240 like we are accustomed to here in the states

Duckweather 01-17-2013 08:03 AM

Also check to see if there is a switch that says 120 / 240 on it somewhere

A heating device designed to work on 220-240 will only use 25% power when connected to 120 volts. It will take forever to heat.
