Is there an idiot proof water heater?

[M Marie M.]

Or do my renters need to stop being idiots?

I'm on water heater #2 and I swore that if anything else went wrong I was going to replace the gas water heater with an electric water heater.

Well I have just been informed that the gas water heater hasn't been working for several weeks. Mainly because the renters failed to pay the gas bill. And every time they fail to pay, the gas company turns off the gas, which turns off the hot water. When the gas get turned back on the water heater has problems. I don't know why, it's less than 3 years old, (because they abused the previous one by leaning crap against it).

So my question is an electric water heater idiot proof?
