About This Data: Operating and 10 year costs are based on US EIA national averages of Electricity ($0.0125/kWh), Natural Gas ($13.50/1000 ft3), and Propane ($3.00/gal). Your state may be higher or lower, so compare relative costs between water heaters. Listed water heater prices are nominal and may vary. Installation costs are assumed $300 (tanks) and $1,000 (tankless).
