So last week our electric water heater was acting a bit weird, changing the temperature of the hot water for no good reason … specifically, making the hot water hotter than it’s supposed to be.
Then we had NO hot water.
I figured out that the thing had tripped its built-in circuit breaker somehow and reset it, and everything was fine until last night.
Last night when I turned on the hot water at the kitchen sink, it came out of the tap boiling. And I’m not just being dramatic in a “Man, it’s boiling hot in here!”, mind you. It was actually boiling as it came out of the faucet, or at least it was within a few degrees of boiling; it bubbled and fizzed and had steam coming out of the faucet along with the water. The water heater’s temperature setting is at 125, where it has always been.
So what the @#$% could be causing this? Are we in danger of having the water heater explode and kill us all? I shut off power to the thing last night and drew off most of the boiling water before turning it back on, and it’s back to normal now, but … huh?
