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 Ariston ARIHPWH-65 that long and it costs about $2,666 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The Ariston ARIHPWH-65 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 $242/year every year.
