I turned the breaker to my water heater off and when I turned it back on my water heater wasn't working. As it is a very old water heater I thought it had gone out, so I replaced it with a new one. It is still not working. The plumber installed it correctly, we filled it, and turned the breaker on, nothing.
The plumber checked the plug going into the hot water heater and it reads 110 on each side because it's a 220 plug. The last water heater we had was 220v 3800w 150 PSI, 30 gallon. This water heater is 240v 4200w. I have two questions. Would the wire test 110 on each side at the water heater if the breaker was messed up? Does the voltage make a huge difference being the old one was 220 and this one is 240?

If the plumber installed the breaker switch correct this isnt an issue. It is normal to have a 240v 4200w breaker. The reading on this switch is correct 110v on each side.
I'm surprised the plumber didn't test this out before he left. I would call him back.
I would suggest you contact your plumber and explain the problem as he should be able to help you with your question. Was there a reason your plumber did not verify your water heater was working properly before he left? He should know (for sure) if the difference in voltage between the old and new heaters will make a difference. Often times some things will work when it is not safe to do so and no one should take a chance with a malfunction in an electrical circuit.
