Weighing a replacement
The A. O. Smith HPSN10-80H45DV 2 runs above its category average. If the electric water heater you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $240/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
At $240/year just to run, a electric water heater is worth protecting against an unplanned repair bill on top of that.
