For electric water heaters including heat pump units. You need to know or convert the unit cost of electricity by kilowatt-hour (kWh). 365 days/year x 12.03 kWh/day ÷ EF x Fuel Cost (\$/kWh) = annual cost of operation. Example: A heat pump water heater with an EF of 2.0 and an electricity cost of \$0.0842/kWh. 365 X 12.03 ÷ 2.0 X \$0.0842 = \$185
