Electric and gas dryers perform the same function — removing moisture from clothes — but use different energy sources with different costs. In most U.S. regions, gas dryers are cheaper to operate per load. However, the upfront cost difference and installation requirements matter too.
Operating Cost Per Load
A standard electric dryer (5,000W) running a 45-minute cycle uses 3.75 kWh → $0.49/load at 13¢/kWh. A gas dryer uses about 0.22 therms of gas per cycle + a small amount of electricity → $0.34/load at $1.30/therm gas. At 5 loads/week, 52 weeks: electric costs $127/year vs. gas at $88/year — a difference of $39/year. Use our Dryer Energy Cost Calculator for your specific rates.
Purchase and Installation Cost
Electric dryers typically cost $400–1,000. Gas dryers cost $450–1,100 — slightly more than comparable electric models. Gas dryers require a gas line connection ($150–300 if not already present) plus a 120V outlet. Electric dryers require a 240V outlet (standard in most U.S. homes). If you don't have a gas line, adding one costs $200–700, which significantly extends the payback period.
Payback Analysis: When Gas Pays Off
If gas dryer costs $100 more than electric and saves $39/year in operating costs, payback is about 2.5 years — not including installation costs. With gas line installation ($300), payback extends to 10 years. If you already have a gas line: gas wins financially. If you need a new gas line: electric is likely better unless you plan to keep the dryer 15+ years.
Heat Pump Dryer: The Most Efficient Option
Heat pump dryers cost $800–1,500 and use about half the electricity of a standard electric dryer ($51/year vs. $127/year). Payback vs. standard electric: 5–8 years on energy savings alone, but heat pump dryers also run at lower temperatures (gentler on fabrics) and don't require external venting. Becoming increasingly popular in Europe and gaining traction in the U.S. as prices fall.
