240v water heater on 120v
I need an electrical wizard to fact check this. I read that if you connect a 240v water heater element on 120v, you draw 1/4 the rated watts.
My goal would be to minimize invertersize. I can't find 120v water heaters with less that 1400watt elements. I'm thinking of a 3000watt, 240v. That should only draw 750watts from the inverter.
I understand my recycle time will increase, but are there any other negatives? Strain on the inverter or batteries, etc?
My alternative is turning everything else off when I want hot water.
