What is the Home Heating Fuel Cost Comparison?
The Home Heating Fuel Cost Comparison Calculator normalizes six major residential heating technologies onto an apples-to-apples cost per Million BTU ($/MMBtu) of delivered heat and projects your total winter heating bill.
Because fuels are sold in completely different physical units—kilowatt-hours (kWh), therms, gallons of propane or #2 fuel oil, and tons of wood pellets—and burned in equipment ranging from 80% AFUE furnaces to 320% COP heat pumps, raw fuel prices never tell the full story.
Adjust local fuel prices, equipment efficiencies, and your home's seasonal heating load to rank every heating option from lowest to highest annual cost and CO₂ intensity.

normalized delivered heat cost ($/MMBtu) and ranked seasonal winter bill across all 6 residential heating technologies
Core Engineering Formula & Industry Benchmarks
Normalizes all fuels to 1,000,000 BTU (1 MMBtu = 293.07 kWh) of actual heat delivered into the living space after combustion or heat-pump COP.

How to Use the Home Heating Fuel Cost Comparison
Gather your baseline utility bills or project specs and enter your values for winter heating load (MMBtu), local rates for electricity ($/kWh), natural gas ($/therm), propane ($/gal), heating oil ($/gal), wood pellets ($/ton), and heat pump COP.
Adjust the interactive sliders or numeric inputs to match your local utility tariff, climate zone, and system size.
Review the real-time calculated metrics—specifically normalized delivered heat cost ($/MMBtu) and ranked seasonal winter bill across all 6 residential heating technologies.
Toggle available incentives (such as the 30% Federal Clean Energy Credit or local utility rebates) to compare gross vs. net payback.
Run a sensitivity check by testing conservative, expected, and high-inflation utility rate assumptions.
Worked Example: Home Heating Fuel Cost Comparison
Real-World Engineering Scenario: Home Heating Fuel Cost Comparison
A northern home requiring 65 MMBtu of winter heat with $0.16/kWh electricity (COP 3.3 heat pump), $1.45/therm gas, $2.75/gal propane, and $3.65/gal oil.
Cold-climate heat pump ($14.21/MMBtu, $924/yr) and natural gas ($15.76/MMBtu, $1,024/yr) beat heating oil ($31.00/MMBtu, $2,015/yr) by over $1,000/yr.
Homeowners on delivered propane, heating oil, or electric baseboard typically cut winter heating bills by 45–65% immediately upon switching to a heat pump.
Key Engineering & Financial Insights
Seal and Insulate Before Sizing HVAC
Upgrading attic insulation to R-49+ and air-sealing rim joists reduces peak Manual J heating/cooling load by 20%–30%, allowing you to buy a smaller, quieter, cheaper heat pump.
Heat Pumps Transfer Heat (300%+ Efficiency)
Even the best condensing gas furnace is capped at 96%–98% AFUE, whereas an inverter heat pump moves 3 to 4 units of ambient outdoor heat for every 1 unit of electrical energy.
Heat Pump Water Heaters Are Fast Payback
Replacing a standard 4,500W electric resistance water heater with a hybrid heat pump water heater saves ~2,500 kWh/year ($400–$600/yr) and dehumidifies basements for free.
Dual-Fuel Balance Point Optimization
If you have a hybrid heat pump + gas furnace system, setting your thermostat switchover to the exact economic balance point temperature prevents burning expensive gas in mild weather.
