110V block heater on 230V?

Hello,
I'm thinking about to start using the factory block heater, but because I live in Europe, only 230V is avilabe from the nework. Will the heater survive the higher voltage, as the excess heat will be dissipated by the coolant, or should I forget it to use it without the right transformator?
Thanks in advance!

I would think not and will pretty quick about letting you know. Not a matter of dissipating heat, element will just fry. Same concept as trying to use a 110v household water heater in a 230 volt application, won't last long.

You can also use some powerful diode to halve 220 volts, if you know what you are doing.

Just a lot easier/cheaper/safer to go have a 220V one installed. Since there's already one there, it quite simply is a matter of undoing one bolt, pulling the old heater, inserting new heater and tightening a bolt.

The hardest part is routing the power cord.

I could have sworn there was a step in there that involved draining your coolant, though I suppose that as soon as you remove the heater it'll do that for you.

Just use a transformer builders use on site, they are cheap to buy. I use one on my 9er sometimes. Check this out:

A voltage divider is built by using resistors.

Are you sure it is a 110V block heater? Unless the Jeep was imported from USA/ Canada, I'm pretty sure it has a 220/230V heater unit installed in it. All the Jeeps I've seen here with block heaters are 220/230V version.

x2 unless the part (or the entire vehicle) was imported from the US/Canadian areas, chances are, it's 230v rated. I have to ask, how is it you believe it's 120v?

And to answer your question.. The extra voltage will burn up the unit, hopefully in a matter of seconds as to avoid possibly causing a fire. Your options are: 1- obtain a power converter, drop it from 230v down to 120v. 2- replace the unit to operate on your native power grids. 3- Plug it in as is and destroy at least the block heater.
