What sits beside it in the ranking
Rheem XE80T10HM00U0 ($264/yr, 1,403 kWh/yr) costs a little more to run than the Rheem PROPH80 T0 RH120-MSO. Rheem PROPH80 T0 RH120-M ($264/yr, 1,403 kWh/yr) costs a little less.
Comparing Rheem's own models
Rheem makes 77 ENERGY STAR certified electric water heaters; this one ranks 75 of 77 for running cost, between the brand's cheapest, the PROPH40 T0 RH120-M at $147/yr, and its priciest, the XE80T10HMS00U0 at $264/yr.
What this adds up to over time
11 years is NAHB's typical service life for this category; at $264/year, the Rheem PROPH80 T0 RH120-MSO adds up to about $2,901 in electricity over that span.
Weighing a replacement
The Rheem PROPH80 T0 RH120-MSO 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 $264/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
Whether or not the Rheem PROPH80 T0 RH120-MSO ever needs replacing, a repair is the more common failure for a electric water heater, one a protection plan budgets for ahead of time.
Sourcing
Nothing here is estimated from a nameplate wattage; the 1,403 kWh/yr is ENERGY STAR's own certified figure for this model. At rank 557 of 596 for running cost, see the electric water heater category page for the rest of the field, or the guide to how much your state matters.
