Reducing the Wattage of an electric Water Heater

This post deals with a question from a visitor wanting to know if you can reduce the wattage of a water heater element without changing the element.

Q: Is there any way to reduce the wattage of a electric
water heater element without changing the element?

I have a 1500W and I would like to reduce it to 750W.

A: The short answer here is no – you have to change the element to one with the correct rating (volts, watts), and one that is approved for the specific appliance as per the manufacturers specifications.

Watt ratings of heater elements are fixed at the rating (watts and supply voltage) specified.
