Default Re: How difficult would it be to convert this water heater from 12V to 6V?

I may be wrong, it has been many decades since I took electrical theory classes, but if the voltage is cut in half the fan speed will be cut by 1/4. Power is volts times current. I think the current is cut in half because the voltage is half and the voltage is half. So 1/2 times 1/2 is 1/4.
