Transformer

You say that the Joule cannot safely handle 240V …why bother?

Just use a transformer to change the 240V in to 120V out.

From a manufacturing perspective there would be legal issues at play. E.g. my thermomix is built for 240 but u bought and use a transformer. They cannot guarantee the unit bc of this. Similar aspects would apply to Joule I suspect.

If you don't give that warning, and someone doesn't have a transformer, and that pertain plugs it in to a 240 outlet, it's going to be a bad day.

Matt: It's not that simple. Joule's heater is a resistive element, which delivers 1100 watts at 120 volts. If you were to plug it into 240 volts, the same heating element will try to draw 4500 watts, since the power of a resistive heating element increases by the square of the voltage. Joule's heating element (at 1100 watts) already has 60% of the power density of a nuclear reactor core in terms of watts per square inch. At 4500 watts the amount of power per square inch is simply too high. So we've included several redundant safety features that will prevent this from actually becoming a problem. Some of these safety features are designed to safely destroy Joule.

The international version of Joule will have a modified heating element that will deliver only 1100 watts at 240 volts.

Why not use a transformer? I suppose you could, but a transformer that can step 240 volts down to 120 volts and deliver 1100 watts looks like this: http://amzn.to/1Qv3tx6 Yeah, it weighs 20 pounds!

TL;DR If you plug the North American version of Joule into a 240 volt outlet, you will break it.

Jesus, Chris, what DON'T you know? Can you tell me what's wrong with my car?

Uh so yeah....I take it Chris knows a thing or two.

I just MIGHT not be able to wait for Joule's European version....we live in HKG and have two of those transformers in use for some of our trusty US appliances....

Wow, that's a new way to make a unclear bomb, quick, call Kim Jong-un.

I’m sorry, I know this is an old post, but couldn’t find another relevant source of information (not counting the very capable tech support of CS). I live in the Philippines where we have 220v sockets, so naturally, I have been using a transformer. I have been using one of those 20-lb transformers that I also use for my stand mixer. My Joule has been working perfectly (and hopefully it will keep on doing so) well until one time, a red, double blinking light started flashing while I was preheating my water bath. I immediately took to my computer to seek help from CS, and they were able to provide me with a neat troubleshooting technique, which instantly fixed my device. My Joule did this once again, a day after it was fixed, but didn’t seem to happen again. I’m not sure if this malfunction has anything to do with the transformer, but I hope somebody can give me answers as to whether I can safely continue my use of Joule or I should immediately cease my use of it until I get a 110-v outlet.
