Right next to it on the list
A rank or two either side of the Ruud PRO H80 T2 RU310BM: Rheem PROUH80 T2 RH350UM ($245/yr, 1,303 kWh/yr), then Ruud PRO H80 T2 RU310UM ($245/yr, 1,303 kWh/yr).
Comparing Ruud's own models
Ranked 46 of Ruud's 51 certified electric water heaters, this sits between the PROUH40 T2 CD400-15 ($121/yr, the brand's cheapest) and the PROUH80 T0 RU120-MSO ($264/yr, its priciest).
Cost over its typical lifespan
11 years is NAHB's typical service life for this category; at $245/year, the Ruud PRO H80 T2 RU310BM adds up to about $2,695 in electricity over that span.
Weighing a replacement
The Ruud PRO H80 T2 RU310BM 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 $245/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
$245/year to run is the predictable cost of the Ruud PRO H80 T2 RU310BM; a protection plan covers the unpredictable one, a repair bill.
Where this number comes from
Nothing here is estimated from a nameplate wattage; the 1,303 kWh/yr is ENERGY STAR's own certified figure for this model. The full Electric Water Heater category page shows all 596 electric water heaters ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
