Article — Gas vs Electric Dryer
At the U.S. average of $0.14 per kWh and $1.50 per therm of natural gas, a gas dryer costs about $74 a year to run against $137 a year for a standard electric model — roughly $63 cheaper per year, or $820 across a 13-year lifespan. Gas dryers cost about $150 more up front, so the operating savings recover that premium in under three years. The gas dryer wins in most U.S. markets, but the answer flips when electricity is cheap (Pacific Northwest), gas is expensive (New England), or you put a heat pump dryer in the comparison.
This piece walks through what each side actually costs, why the gas dryer payback works out so quickly in average conditions, and the two scenarios that overturn the default answer.
Which dryer is actually cheaper to run
The U.S. Department of Energy benchmarks a standard vented electric dryer at about 4.5 kWh per load and a standard vented gas dryer at about 0.35 therm. At national average rates, that works out to roughly $0.63 per electric load versus $0.53 per gas load — before efficiency adjustments. After dividing through efficiency (75% electric, 85% gas), the gap widens further.
For an average household of six loads per week (312 loads per year), the annual numbers settle around $197 electric and $164 gas. Across a 13-year lifespan that is a lifetime operating spend of $1,780 for electric and $960 for gas — an $820 gap in favour of gas before purchase price and maintenance enter the picture.
About 80% of U.S. households use an electric dryer and roughly 20% use gas, according to the Energy Information Administration's Residential Energy Consumption Survey. The split is geographic: gas dominates in regions with built-out natural-gas distribution (the Midwest, Mid-Atlantic, parts of California), and electric prevails elsewhere — especially in rural areas and the Southeast where new home construction skipped gas entirely.
Gas vs electric dryer purchase and install
Pure appliance price is close. Standard electric models run $400–$800 and standard gas models $600–$1,200. The $150–$200 gap reflects the gas valve, ignition assembly, and stricter venting components. Identical-spec models from a single brand often sit within $100 of each other.
The bigger split is installation. An electric dryer plugs into a 240V outlet you almost certainly already have if the laundry hookup is wired for a dryer at all. A gas dryer needs a quarter-turn shutoff, a flexible appliance connector, and a leak test. If the laundry space lacks an existing gas line, a plumber will charge $500–$2,000 to run one in, depending on distance and how much wall has to come down. That number can easily turn the gas premium into a 5–7-year payback rather than 3.
- Standard electric purchase — $400 to $800 (installed)
- Standard gas purchase — $600 to $1,200 (appliance only)
- New gas line install — $500 to $2,000 if absent
- 240V electric outlet install — $300 to $800 if absent
- Gas dryer venting upgrade — $100 to $400 if existing vent insufficient
- Annual maintenance gap — gas $40–$80, electric $20–$50
How much energy a dryer really uses
The DOE classifies clothes dryers as the third-largest household energy use after heating/cooling and water heating. A typical electric dryer pulls roughly 5,500–6,500 watts during a cycle, drawing 4–5.5 kWh across a 45-minute load. A gas dryer uses similar electricity for the motor and controls (around 0.2 kWh per load) plus 0.30–0.40 therms of natural gas for the burner.
Efficiency is the part the spec sheet rarely highlights. The DOE Energy Factor (EF) rating measures pounds of clothing dried per kWh-equivalent. Standard electric dryers run 2.5–3.3 lb/kWh, gas dryers 2.8–3.5 lb/kWh (the DOE converts therms to kWh-equivalent for this measure). ENERGY STAR certified models must hit at least 20% better than minimum — useful, but small relative to the 60%+ gain a heat pump model delivers.
A clogged or kinked dryer vent forces the unit to run 30–50% longer per load and accelerates wear on the heating element or burner. The U.S. Fire Administration links failure to clean the lint screen and venting to roughly 2,900 home structure fires per year. Clean the trap every load, vacuum the dryer venting at least once a year, and replace flexible foil ducting with rigid metal where possible.
When the gas dryer payback makes sense
In an average U.S. market, an extra $150 to put gas in instead of electric recovers in 2 to 3 heating seasons of laundry. After that, every load is pure savings — $820 over the appliance's life at typical use, more for big families. That is why utility rebate programs targeting carbon often prefer to subsidise heat pump electrics rather than fight a fight they will lose against gas.
The math flips in three situations. First: cheap electricity. In Washington, Idaho, parts of Tennessee and Kentucky where hydroelectric or nuclear baseload pulls residential rates under $0.10/kWh, gas can no longer beat electric on operating cost. Second: expensive gas. In parts of New England and California where delivered natural-gas rates hit $2.30/therm or more, the gas operating premium evaporates. Third: a missing gas line. If you need a plumber to run gas to the laundry, the install cost can wipe out a decade of operating savings before you start.
The federal Inflation Reduction Act of 2022 made ENERGY STAR heat pump dryers eligible for state-administered rebates of up to $840 (income-qualified households) under the High-Efficiency Electric Home Rebate Program. The funding rolled out through 2024 and 2025 by state. The Database of State Incentives for Renewables & Efficiency (DSIRE) tracks active programs.
Where heat pump dryers fit in
Heat pump dryers are the disruptor in this comparison. Instead of generating heat with resistance coils or a burner, they cycle refrigerant to extract heat from the dryer air, condense out the moisture, and recycle the warm air back through the drum. They use 50–60% less energy than standard electrics — effective efficiency of 200–300%, since they move heat rather than create it.
At 4.5 kWh per load standard versus roughly 2.0 kWh for heat pump, a heat pump electric drops annual cost to about $44 at average U.S. rates — well below the gas dryer's $74. The catch is purchase price: $1,000–$1,800 versus $400–$800 for the equivalent standard electric. The premium recovers over 8–12 years in most U.S. markets, faster in California and the Northeast where electricity is expensive.
Heat pumps run at lower temperatures — about 120 °F instead of 145 °F — so cycles run 60–90 minutes instead of 45. They also need an empty water reservoir or a drain hookup, since no vent carries moisture outside. If you currently run two loads back-to-back to clear daily laundry, you may not have time for a heat pump model on weekdays.
Common gas vs electric dryer mistakes
The appliance price gap is small ($150). The install gap can be enormous ($500–$2,000 if a gas line has to be run). Always price the full installed cost before deciding. A gas dryer that needs a new line often loses the payback race outright.
Electricity and gas rates rise — usually 2–4% per year in nominal dollars. The U.S. Energy Information Administration's projections suggest electricity may outpace gas over the next decade as the grid carbonises. If your local utility has announced rate hikes, model the higher number rather than today's bill.
ENERGY STAR certification covers standard, condenser, and heat pump electric dryers, plus standard gas dryers. The yellow EnergyGuide label shows the estimated annual kWh use — a standard ENERGY STAR electric will sit around 540 kWh/year, a heat pump model around 270. Read the number, not just the logo.
An electric dryer on a renewable-heavy grid (Washington, Vermont, California after dark) emits roughly 0.5–1 kg CO&sub2; per load. A gas dryer emits 2–3 kg CO&sub2; per load regardless of grid mix. If your operating cost gap is under $20/year, the climate case for electric is solid even at break-even economics.
