Unregistered said:One of my tenants reported 'no hot water'. After visiting the site, I found that the 208/220V Electric water heater was being fed by a 120V single phase circuit. However, the water heater had been operating for at least five years. I was surprised that the water heater ever worked however I rewired the top element feed to the bottom element assuming that the top element was bad. I did this as a temporary fix until I can get 220V feed to the location and either replace the top element or the whole water heater.
Question, has anyone ran into this situation before? Will 220V heaters actually run on 120 V?

The heater was a 2-element duplex. I replaced the heater and ran a new 220V 2P #10 feed to the new heater and all is well. Thanks to everyone for their comments.Bjd said:Hi Guys
In looking at this post I must ask, the breaker that is supplying the heater is it a duplex or a single? If its a duplex you may have a bad side to it, that would send only one leg to the heater,giving the inpression of being only 115 vt.
