This hot water heater is only 1 1/2 years old. (I was able to snag a deal on a hybrid, so I'm upgrading along with some other appliances.)
Heater is AOSmith model ECT 66 210.
I found new ones online for ~$650. I'll offer this one up for $450 OBO.
It will be available in a couple of weeks after my new heater arrives.
PM me for questions/contact info.
