ive just bought a instant water heater the type you get in pub toilets, any way ive just realised it is the 7kw version that runs of 400 volts, the problem is my power supply is only 230 volts
was wondering if i connected it too my power supply would it run of 230 v or would this cause a overload and be potentially dangerous??????

I am based in the uk, I purchase the item of ebay a few months back funny thing is it said it was ideal for any application, but how many homes run 3 ways? it would be fine if the 230 v caused it to run at half its power as thats still 3.75 kw but i need too be certain of this before I install

This depends if you have single phase power or 3 phase. 480V equipment will only run on 3 phase power. Most residences only have single phase. If you do have 3 phase power you would need a booster transformer to convert your 240V primary to 480V. This could be very expensive for a little hot water heater.
I think your best bet is to take it back and buy one that matches your electrical service.

Basically You need that 400 volts for it to operate properly.
Check your service panel to see if you have 2 separate 230 lines and if you do, a line off of each one to a proper receptacle. It's best to find out if you have the voltage you need from an electrician. In the US we have 120 volt appliances and two lines into the building bringing 240 if both lines are used together. This enables 220/240 volt appliances to work quite nicely. We also have the option for a commercial feed (more money) and 440 three phase power which some industrial appliances need to operate. Check it out, ask a pro and also there are step-up transformers out there (make sure you get the right size and it's gonna be big) although the cheapest way for you to go.
Good luck ! ! !

If the heater is radiant or baseboard variety devoid of fan, the warmth output would be a pair of million/4 of the score. it somewhat is considering the fact which you have a pair of million/2 the voltage, this might reason the heating element to charm to a million/2 the present. the genuine calculations are one hundred twenty/230 X one hundred twenty/230 X six hundred = 163 Watts If the heater has a fan, the motor might in all probability no longer flip quickly adequate to kick back itself correct. there is an stable danger the motor will fail.

You will be fine with your heater. It is going to run slower and will not reach full power. Your line current is going to be doubled with 230V versus 400. your main draw will be up to 28 amp on peak wich may trip the circuit breaker. But most likely it will never run at full power and you will get half of the KW rating.

First of all, you never mentioned what country you are in. It could be a non-US compatible one. Voltages in Europe are higher across two legs and leg to neutral. I THINK in Italy it was 220/440. Like Stobal said, here in the US the only way you would reach that voltage is going to cost more that the value of that appliance. Call a local electrician, that would be your safest action.

The voltage of mains is the average ammount of electricty processes at that point at any one time.
You should have no problems.
