How it works

Cost = heat needed ÷ (fuel energy × efficiency) × price. Energy content: heating oil 138,500 Btu per gallon, propane 91,452 Btu per gallon, electricity 3,412 Btu per kWh (EIA). A heat pump’s seasonal COP depends on the model and your climate; colder places see lower values. EIA surveys heating oil in 21 states and propane in 38; where your state isn’t surveyed, enter your dealer’s price.
