What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical electric water heater's service life at 11 years; run the Rheem PROPH80 T2 RH400-SO that long and it costs about $2,508 in electricity, on top of whatever it cost to buy.
Weighing a replacement
The Rheem PROPH80 T2 RH400-SO 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 $228/year every year.

Protecting what you have
At $228/year just to run, a electric water heater is worth protecting against an unplanned repair bill on top of that.
