I live in FRANCE. I have a electrical box near my water heater that has three lives wires and an earth. Using a multimeter I get 407v across each pair on live cables, and 230v across each live cable to earth. There is no neutral wire. I would like to get 230v but not using the earth.
1phase from 3 phase?

you need a supply with a neutral. other than that, youll need a 400/230v transformer
if I remember correctly the French don't use an earth anyway.
A lot of French stuff has no neutral,
They just take it to earth ,
In reality it's the same thing at star point anyway.
It's only if you need RCD protection it becomes an issue, but most french electrics are a bit agricultural at best, to put it mildly.
If you do need protection you could always use an isolating Tx across L/E

I ran 1.5mm single copper wire a neutral back to the main fuse box and connected to one of the three phases. Tested at 230v. All good, it worked last night, so now I get the cheaper electricity tariff between 1am and 7am. The cheaper tariff three phase supplied to the house here in France is automatically switched on and off at the main fuse board by a signal generated by the supply company (EDF), so I don't need a timer for my Chauffe Eau - hot water boiler.

How much power does this water boiler consume. I'm not au fait with French regulations but how did you run this new neutral. Also "borrowing" a neutral from another source of supply could leave a dangerous situation for anyone working on it.
