[Shop-talk] Wiring a 230v 50hz heater for U.S. 220v 60hz supply

[DAVID MASSEY]

 First off, a resistance heater don't care about frequency.  It will be happy with DC.  

If the thermostat is just the old-school mechanical bi-metal thermostat (still the cheapest way to go) it will work just fine on 60 Hz, too.  If there are electronic controls the odds are really good that they will work just fine (actually better?) at 60Hz vs 50Hz.
BTW most line-powered electronics these days will work on either 50 or 60 Hz and many will work over the 90 -264 Volt range making then suitable for use in US and EU.

C'est simple. Cette plateau de chauffage va marche bien chez toi !

BTW, I'm jealous.  Do you need someone to carry your bags?

Guys,
I'm in France right now. I'd like to buy what amounts to a hot plate here. The company that makes these sells them all over the world. In France (where the manufacturer is located) they're about $300. In the U.S., they're about $900. A huge chunk of that is just how common they are in France and uncommon they are in the U.S.--at home they're sold through a partner licensee.
Anyway, the one I'd buy in France has a French plug on it for 230v 50hz supply. The specialty retailer offering it says I can replace the plug with a U.S. 220v plug and it'll work just fine. Either cut it and wire on a dryer plug or unscrew the plug in the unit and install a dryer plug. This is also coming from a sales guy.
The electronics are are literally an electric resistance coil sunk in an iron plate and a thermostat dial, and a light to indicate when it's at temp. I'm trying to come up with his any of those would change with the 10hz frequency difference.
The U.S. version is at least cosmetically identical, and literally the only parts aside from the coil are the thermostat dial and light. The function is the shape of the iron plate--the rest is just a heating blanket. I wouldn't want to switch it to 120v U.S.--it would take forever to get up to temp. and to recover during use.
Does it seem reasonable that I can just swap out the cord? Any thoughts?
Thanks fellas.
