Electric Heating vs. Gas Heating: A Real Cost Comparison
The question of whether to heat your home with electricity or natural gas is not just a technical decision — it is an economic one that plays out in your monthly utility bills for as long as you own the home. And with energy prices fluctuating more wildly than they have in decades, getting this decision right matters more than ever.
This is not a simple question to answer. The cost comparison depends on your local utility rates, your climate, the efficiency of your equipment, and whether you are comparing operating costs only or factoring in equipment and installation costs too. This guide gives you the framework to make the right call for your situation.
Understanding the Fuel Cost Fundamentals
Before comparing any specific costs, you need to understand how the two energy sources are priced and why that matters.
Natural Gas: Volatile but Usually Cheaper Per BTU
Natural gas is priced in therms or cubic feet (CCF). As of 2026, residential natural gas prices in North America average roughly $1.00–$1.50 per therm, though this varies significantly by region — from around $0.70/therm in gas-producing regions like Texas and Pennsylvania to over $2.00/therm in regions like California and New England where gas infrastructure is older and taxes are higher.
Natural gas prices are volatile — they spiked dramatically in 2022 and have been relatively high since. However, gas remains typically cheaper per BTU of heat than electricity in most markets.
Electricity: Stable but More Expensive Per BTU
Residential electricity is priced in kilowatt-hours (kWh). Average US residential electricity rates in 2026 run approximately $0.12–$0.16/kWh nationally, though this ranges from around $0.08/kWh in hydro-rich states like Washington and Idaho to over $0.25/kWh in Hawaii, California, and parts of New England.
The problem for heating is that electricity is roughly three times more expensive per BTU than natural gas, even in favourable markets. One therm of natural gas (roughly 100,000 BTU) costs about $1.00–$1.50. Producing the same 100,000 BTU with electric resistance heat costs approximately $3.00–$4.00 at average US electricity rates.
Why the BTU Comparison Matters
The fundamental physics advantage of natural gas is combustion efficiency. A gas furnace converts 90–98% of the fuel’s energy into heat (its AFUE rating). Electric resistance heat converts nearly 100% of electrical energy into heat — but the electric meter measures the energy after the power plant converted fuel into electricity, and that conversion is only about 30–45% efficient.
By the time electricity reaches your home from a power plant, burning gas to make electricity, transmitting it over long-distance power lines, and distributing it locally, the overall efficiency of using gas for electric heat at your house is far worse than just burning the gas directly in your furnace.
Heat pumps change this equation significantly (more on that below).
Direct Operating Cost Comparison
Here is what heating your home actually costs under different scenarios. These are approximate annual heating costs for a typical 2,000 square foot home in a cold climate (5,000+ heating degree days) assuming:
- 80 million BTU heating load per heating season
- Average local utility rates
| Scenario | Efficiency | Energy Required | Cost Per Unit | Annual Heating Cost |
|---|---|---|---|---|
| Standard gas furnace (80% AFUE) | 80% | 100 MMBTU | $1.20/therm | $1,200 |
| High-efficiency gas furnace (95% AFUE) | 95% | 84 MMBTU | $1.20/therm | $1,008 |
| Heat pump (HSPF 9) | 2.6 COP | 31 MMBTU electric | $0.14/kWh | $1,270 |
| Cold-climate heat pump (HSPF 12) | 3.5 COP | 23 MMBTU electric | $0.14/kWh | $920 |
| Electric resistance (baseboard) | 100% | 80 MMBTU | $0.14/kWh | $3,290 |
Key takeaways from this comparison:
- Gas furnaces remain the lowest direct operating cost option in most markets
- Cold-climate heat pumps are increasingly competitive in areas with moderate electricity costs
- Electric resistance heating is dramatically more expensive and should be avoided as a primary heat source
When a Heat Pump Changes the Equation
The comparison above is for conventional heating equipment. Heat pumps fundamentally change the cost picture because they do not generate heat — they move heat from outdoors to indoors. For every unit of electricity they consume, they move 2–4 units of heat energy.
A heat pump with a coefficient of performance (COP) of 3.0 delivers 3 BTUs of heat for every 1 BTU of electricity. This is three times more efficient than electric resistance heat and — under the right conditions — can compete with natural gas on operating cost.
When Does a Heat Pump Beat Gas?
A heat pump beats gas heating when:
- Your electricity rate is low (under $0.12/kWh) relative to your gas rate (over $1.00/therm)
- Your climate is mild (under 3,000 heating degree days)
- You install a cold-climate unit (which maintains efficiency at temperatures below 25°F)
- You have dual-fuel capability (heat pump handles most of the heating season, gas furnace covers extreme cold)
When Does Gas Still Win?
Gas heating remains more economical when:
- Natural gas is very cheap (under $0.80/therm) and electricity is expensive (over $0.18/kWh)
- Your climate is very cold (over 6,000 heating degree days) where even cold-climate heat pumps struggle
- Your heat pump would be standard (non cold-climate) in a cold climate
- You have an older, inefficient gas furnace that you are not replacing at the same time
Equipment and Installation Cost Comparison
Operating cost is only part of the picture. Equipment and installation costs differ significantly:
| System | Equipment Cost | Installed Cost | Lifespan |
|---|---|---|---|
| Gas furnace (standard, 80K BTU) | $1,500–$2,500 | $3,000–$5,500 | 15–20 years |
| Gas furnace (high-efficiency, 80K BTU) | $2,500–$4,500 | $5,000–$8,000 | 18–25 years |
| Heat pump (ducted, 3-ton) | $3,000–$6,000 | $6,500–$11,000 | 15–20 years |
| Cold-climate heat pump (ducted) | $4,500–$7,500 | $8,000–$14,000 | 15–20 years |
| Ductless mini-split heat pump | $1,500–$4,000 per zone | $3,000–$7,500 per zone | 15–20 years |
| Electric furnace (80K BTU) | $1,000–$2,000 | $2,500–$4,500 | 20–25 years |
| Electric baseboard (zonal) | $150–$400 per room | $200–$600 per room | 25–30 years |
Heat pump installations are typically 40–60% more expensive than gas furnace installations upfront. However, heat pumps also provide summer cooling, so if you currently have no air conditioning, a heat pump replaces both a furnace and a central AC unit — bringing the cost comparison closer to even.
The Carbon and Sustainability Angle
If environmental impact is part of your decision, the picture is more nuanced than “electric is clean, gas is dirty.”
Direct Emissions
A gas furnace burning natural gas produces carbon dioxide directly at your home. A heat pump produces zero direct emissions. In terms of direct household carbon footprint, the heat pump wins.
Full-Cycle Analysis
However, the carbon comparison depends heavily on how your regional electricity grid generates power. In regions where the grid is powered primarily by coal, a heat pump may not provide significant carbon advantages over a high-efficiency gas furnace. In regions with substantial renewables (hydro, wind, solar), a heat pump’s carbon advantage is substantial and growing as grids decarbonize.
As of 2026, the Union of Concerned Scientists estimates that heat pumps reduce household carbon emissions by 40–60% compared to gas furnaces in most US markets, with the advantage growing each year as grids decarbonize.
The Long View
If you are making a 20-year investment in a heating system, you are investing in the energy landscape of 2035–2045, when renewable grid penetration will be significantly higher than today. A heat pump installed in 2026 will likely provide substantially better carbon performance over its lifetime than its operating cost comparison to gas would suggest today.
Hidden Costs and Considerations
Infrastructure Costs
If you are building new or converting fuel types, infrastructure costs can swing the decision:
- Converting to gas: Requires running a gas line. If your neighbourhood already has gas service, connection costs $500–$2,000. If you are in a rural area without gas mains, costs can reach $10,000–$30,000.
- Converting to electric: Requires adequate electrical panel capacity (200 amp service is standard). If your panel is 100 amps or smaller, an upgrade runs $2,000–$5,000.
- Heat pump electrical upgrades: Heat pumps may require dedicated 30–60 amp circuits depending on size. An electrician typically charges $300–$800 per circuit.
Maintenance and Repair Costs
- Gas furnaces require annual servicing, flue inspections, and occasional heat exchanger or igniter replacements. Annual maintenance: $100–$200.
- Heat pumps require biannual servicing (check refrigerant, clean coils, check electrical connections). Annual maintenance: $150–$250.
- Electric systems have fewer moving parts and generally lower maintenance costs. Annual maintenance: $75–$150.
Safety Considerations
- Gas: Combustion products include carbon monoxide — requires properly maintained venting and CO detectors. Combustible fuel carries ignition/explosion risk.
- Electric: No combustion products, no carbon monoxide risk. No fuel on site. Generally considered safer.
How to Decide: A Decision Framework
Answer these questions in order:
- Is natural gas available at your property? If yes, compare gas furnace vs. heat pump. If no, the decision is heat pump (or electric) and you skip to step 3.
- Is your existing gas furnace old (over 15 years) or inefficient (under 85% AFUE)? If yes, replacement costs are coming regardless — factor them in. If no, compare operating costs only.
- Do you need air conditioning? If yes, a heat pump replaces both heating and cooling — value this benefit in the comparison. If no, compare heat pump vs. gas furnace on heating costs alone.
- What is your electricity cost per kWh vs. your gas cost per therm? Use the rule of thumb: if electricity is more than 12× the gas price per unit (adjusted for efficiency), gas is cheaper to operate. If less than 10×, heat pump is cheaper.
- How cold is your climate? Below 4,000 heating degree days: heat pump likely wins on operating cost. Above 6,000: gas is likely cheaper. Between: it depends on equipment efficiency and rates.
- How long do you plan to stay in the home? If under 5 years, upfront cost difference may not be recovered. If over 10 years, operating savings likely justify premium equipment costs.
Frequently Asked Questions
Is it cheaper to heat with gas or electricity?
In most North American markets, natural gas is currently cheaper to operate than electric resistance heat. However, a heat pump (which uses electricity but moves heat rather than generating it) often matches or beats gas on operating cost, depending on your climate and local utility rates.
Will a heat pump work in a very cold climate?
Yes, with the right unit. Cold-climate heat pumps maintain effective heating output and efficiency down to -15°F to -25°F. Standard heat pumps lose significant capacity below 25°F. In climates with extended sub-zero temperatures, a dual-fuel setup (heat pump + gas furnace) is often the best solution.
How long does a gas furnace last compared to a heat pump?
A well-maintained gas furnace typically lasts 15–20 years, with high-efficiency models sometimes reaching 25 years. Heat pumps average 15–20 years before requiring major compressor or coil replacement. Electric furnaces and baseboard heaters can last 25–30 years due to their simpler construction.
Should I replace my gas furnace with a heat pump?
If your gas furnace is more than 15 years old and you are considering replacement, it may be worth evaluating a heat pump as a gas furnace replacement — especially if you also need air conditioning, live in a mild-to-moderate climate, or want to reduce your carbon footprint. However, if you live in a very cold climate with inexpensive gas and an older heat pump may not perform well, a high-efficiency gas furnace replacement may be more practical.
Do utility companies offer rebates for heat pumps?
Yes. Federal tax credits under the Inflation Reduction Act provide 30% of installed cost (up to $2,000) for air-source heat pumps. Many utilities offer additional rebates of $500–$2,500. Canadian homeowners can access the Canada Greener Homes Grant (up to $5,000 for heat pumps). Check with your utility company and provincial/state energy programs before purchasing.
