380V water heater element running with 220V to reduce power?

bionut · Jul 28, 2015

Hello, i was thinking about buying a 9000W 380V element and plug it in a 220V outlet to reduce the power to around 5000W. Is this posible? If so, how can i reduce the power even more?

I need to say that is very expensive to get ULWD elements here.

The formula is 220v squared divided by 380v squared
or 33.5 percent of 9000w
you will get 3016 watts out of the element

You can put a power diode in series with the element so that it only conducts during one half of the cycle thus producing half the usual power or about 1500 W.

3000w is even better, thanks. I did nkt kbew the formula.
