Propane vs Electric Heating: Cost Comparison with Heat Pumps (2026)

Electric resistance is more expensive than propane. Heat pumps are cheaper than propane. The type of electric heating matters enormously.

Annual cost based on 75 million BTU heating load (approximately 1,000 gallons of propane equivalent). Electric rate: $0.16/kWh (2026 US average). Install costs vary significantly by region, home size, and existing ductwork.

Why Heat Pumps Change the Comparison Entirely

Heat pumps do not generate heat from electricity - they move heat from outside air into your home. This is why they can deliver 250 to 400% efficiency (a COP of 2.5 to 4.0). A conventional electric resistance heater converts 1 unit of electrical energy to 1 unit of heat. A heat pump converts 1 unit of electrical energy to 2.5 to 4 units of heat by moving it from outdoors.

At COP 3.0 and $0.16/kWh electricity, a heat pump costs $1.56 per 100,000 BTU - less than half the cost of propane at $3.19. In mild and moderate climates, this efficiency is maintained year-round. The catch: heat pump efficiency drops as outdoor temperature falls, which is why cold-climate applications need more consideration.

Recommendation by Climate Zone

Mild Climate
Texas, Florida, Georgia, Arizona, California
Recommended: Heat Pump

Temperatures rarely below 20F. Heat pump maintains COP 2.5+ nearly all season. Saves 40-50% vs propane. Standard heat pump (no cold-climate specs needed).

Moderate Climate
Virginia, Ohio, Missouri, Oregon, Washington
Recommended: Heat Pump

Some winter days below 20F but infrequent. A quality cold-climate heat pump covers 90%+ of heating hours efficiently. Excellent ROI in 5-8 years.

Cold Climate
Minnesota, Wisconsin, Maine, Vermont, Michigan
Recommended: Dual-Fuel HP

Frequent temperatures below 0-15F. Best option: cold-climate heat pump (Mitsubishi Hyper-Heat, Bosch IDS) + propane backup. Heat pump covers 85% of hours; propane handles the coldest days.

Extreme Cold
Northern Minnesota, Montana, Alaska
Recommended: Propane Primary

Sustained sub-zero temperatures limit heat pump economics. Propane remains competitive. High-efficiency propane furnace (95%+ AFUE) with modest heat pump supplement where practical.

Propane vs Electric FAQ

Is propane or electric heating cheaper?
It depends on the electric system. Electric resistance heating (baseboard heaters, older electric furnaces) costs $4.69 per 100,000 BTU at $0.16/kWh, making it 47% more expensive than propane at $3.19 per 100,000 BTU. Heat pumps at COP 3.0 cost just $1.56 per 100,000 BTU, making them 51% cheaper than propane. The key is which type of electric heating you are comparing.
Do heat pumps work in cold climates?
Modern cold-climate heat pumps (like the Mitsubishi Hyper-Heat and Bosch IDS series) maintain significant efficiency down to -13F (-25C). Most cold-climate heat pumps reach COP 2.0 or above at temperatures down to 0F. Dual-fuel systems (heat pump + propane backup) are an excellent option for the Northeast and Midwest: use the heat pump for most of the heating season and switch to propane when temperatures drop below the heat pump's efficient range (typically 0 to 15F).
Should I switch from propane to a heat pump?
Run the numbers for your specific situation. Key factors: your local electricity rate, your climate zone, your current propane usage, and the installation cost of a heat pump for your home size. In mild and moderate climates with electricity rates below $0.18/kWh, heat pumps almost always win economically. In cold climates, a dual-fuel heat pump + propane backup is often the best solution. The Inflation Reduction Act provides up to $8,000 in federal tax credits for heat pump installation through 2032.
What about propane vs electric water heaters?
Propane water heaters cost $556 to $834 per year to operate vs $480 to $700 for an electric resistance water heater. However, heat pump water heaters cost only $200 to $350 per year to operate, making them significantly cheaper than both propane and electric resistance. If you are replacing a water heater, a heat pump water heater (also eligible for federal tax credits) is worth serious consideration regardless of your home's primary heating fuel.
