Hello,
About four months ago, I replaced one of the elements on my water
heater (240V / 4500W per element - heater's about 5 or 6 years old).
There are two elements on the heater, and the upper element seemed
fine so I left it alone. Yesterday, the new element failed. I pulled
it out and found a hole blown in the element. This time I replaced
both elements and both thermostats.
Can someone explain some things to me.
1. Why did the new element fail so soon?
2. Why are there two thermostats?
3. Should the lower thermostat be set at a different temperature than
the upper one?

thanks

1 likely made in China, return it, it should have a warranty

I have a question. why did you replace all the parts when only one was
bad?

Maybe you should read it again?

It should be noted that the heater is very difficult to get to. It is
difficult to explain just how hard it is, but it takes about an hour
just to get to the heater. So I want to minimize the number of times
I have to access the heater. The heater is a 6 year system, and it is
around 6 years old. I figured it was a safe bet to replace everything.
