Weighing a replacement
The Lennox WHHP065T45MD240S 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 $230/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
At $230/year just to run, a electric water heater is worth protecting against an unplanned repair bill on top of that.
