How Much Does It Cost to Run a Dryer?
Electric dryers cost $0.30-0.75 per load (2-5 kWh at $0.16/kWh). Gas dryers cost about $0.15-0.35 per load. Running 8 loads weekly costs $12-24/month for electric, $5-11/month for gas. Use the Power Cost Calculator for your exact costs.
Key Takeaways
- Electric dryers are the most power-hungry household appliance, using 2,000-5,000 watts.
- Heat pump dryers use 50% less energy but cost more upfront and take longer.
- Air-drying on a rack or line costs nothing and extends fabric life.
Explanation
Electric dryers are the most power-hungry household appliance, using 2,000-5,000 watts. A typical cycle uses 2-5 kWh depending on load size, moisture level, and cycle length.
Gas dryers use about half the energy cost of electric because natural gas is cheaper than electricity per BTU. However, gas dryers still use some electricity for the drum motor and controls.
Drying time affects cost significantly. Clean the lint trap every load and the vent annually—clogged vents increase drying time by 30% or more. Moisture sensors help stop cycles when clothes are dry.
Heat pump dryers recycle hot air instead of venting it outside, achieving 50% lower energy consumption than conventional electric dryers. They operate at lower temperatures (110-130°F vs 135-150°F), which is gentler on fabrics and reduces shrinkage. The tradeoff is longer cycle times—typically 60-90 minutes versus 40-60 minutes for vented dryers.
Dryer vent length and routing directly affect efficiency. Every 90-degree bend in the vent duct adds the equivalent of 5-10 feet of straight duct in terms of airflow resistance. A vent run exceeding 25 feet (including bends) restricts exhaust flow significantly, increasing dry times by 20-40% and raising the per-load cost accordingly. Rigid metal ducts outperform flexible foil or vinyl ducts in airflow and safety.
Separating laundry by fabric weight before drying reduces energy waste. Lightweight synthetics dry in 20-30 minutes while heavy towels and jeans need 50-70 minutes. Mixing them forces you to run the cycle long enough for the heaviest items, over-drying the lighter fabrics and wasting 15-25% of the cycle's energy on already-dry clothing.
Running consecutive dryer loads is more efficient than spacing them hours apart. The dryer retains heat from the previous cycle, so the second and third loads start with a warm drum and heated vent duct. This reduces the energy needed to reach operating temperature by roughly 10-15% per subsequent load compared to a cold start.
