How we calculate this
Annual energy use (893 kWh a year) is the figure the manufacturer filed for this model with the EPA, in the ENERGY STAR certified product database. Running cost is that figure multiplied by a state's average residential electricity price from the U.S. Energy Information Administration (12-month average through July 2026, average revenue per kWh).
The annual figure for a water heater assumes a hot water draw of 10, 38, 55 or 84 gallons a day, set by the heater's first-hour rating, per the DOE test procedure (10 CFR 430 Subpart B, Appendix E). Full methodology.
