Heat Pump Water Heater Calculator
Calculate the energy savings, payback period, and annual operating costs of a heat pump water heater. Compare with traditional electric and gas water heaters.
Step 1: Energy Costs & System
Understanding Efficiency Ratings
Standard electric water heaters have EF around 0.95. Natural gas heaters have EF around 0.65. Heat pump water heaters have COP values typically between 2.5-3.5 (equivalent to 250-350% efficiency).
Step 2: Household Usage
About Hot Water Usage
The average person uses about 16 gallons of hot water daily. A 4-person household typically uses 64 gallons. Higher temperature settings and colder incoming water increase energy consumption.
