If your water heater gave out a few years sooner than you expected, you're not unlucky — you're living in Central Florida. The single biggest reason tanks fail early here has nothing to do with the brand on the label and everything to do with what comes out of the tap.
Orlando sits on a limestone aquifer, which means the water is loaded with dissolved minerals — it's some of the hardest water in the state. Every time your heater warms that water, a little of those minerals drop out and settle as scale on the bottom of the tank. Over years, that layer builds into a crust.
That crust forces the burner or element to work through an insulating layer of rock to heat the water above it. The tank runs hotter and longer, the steel fatigues, and you'll often hear it — a rumbling or popping sound is sediment boiling underneath. A tank rated for 10–12 years can give out in 7 or 8 when it's never been flushed.
Flush the tank once a year. In most of the country that's an every-other-year chore; in Orlando it's annual because the scale builds so fast. While it's open, it's worth checking the anode rod — that sacrificial rod corrodes so your tank doesn't, and a spent one is a quiet death sentence. A yearly flush is cheap insurance against an early water heater replacement.
If the tank itself is leaking, the water runs rusty, or it's past about eight years and acting up, you're usually better off replacing than repairing. That's also the natural moment to weigh a tankless upgrade — just know tankless needs its own annual descaling on our water. Not sure which way to go?

Once a year. Our hard water builds sediment fast, so the usual every-other-year advice doesn't hold here.
Yes — removing the sediment layer lets the heater run cooler and more efficiently, which is the main thing that buys back years.
