Ele water heater


I have a reliance 30 gal ele water heater with two 4500 elements that are 240 v rated on a 30 amp breaker.

I want to use this w/heater at another location with a 220v 20 amp breaker.

Can I just change the elements, say to 3800w and bring the amp rating down to 20 amps.

It shouldn't matter to the two thermostats because they are both rated at 220 v.

Theoretically you that works. It won't be certified anymore, unless it's an OEM listed part with a nameplate update sticker. If it's your own house, you should be good either way.


PS. That sounds like its combined 4500W. 30A at 240 is only 7200W

Cheers!

Just a thought; assuming you can do it technically and legally, I would think your hot water production will suffer, since your energy into the system at max would be decreased by 33%. Would take longer to recover IMO.
