Is it worth replacing?
The Lochinvar CHPA-80 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.

Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. 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.
