Quick answer
A typical electric clothes dryer uses about 1,800 to 5,000 watts, according to Penn State's EGEE 102 appliance table, depending on the model and the heat setting. Most of that is the heating element; the drum motor is a small share. Your dryer's exact rating is on its rating label, usually in watts or kilowatts at 240 volts. The element cycles on and off as the drum reaches temperature, so the average draw over a load is lower than the rating. For kWh, multiply watts by hours and divide by 1,000: a dryer averaging 3,000 watts for 45 minutes uses about 2.25 kWh. A gas dryer uses gas for heat and electricity only for the motor and controls. ENERGY STAR says heat pump dryers use around 70% less energy than conventional dryers.
An electric clothes dryer is one of the largest loads in most houses, and one of the few that runs on its own 240-volt circuit. Penn State's EGEE 102 course puts a clothes dryer at about 1,800 to 5,000 watts, and its larger appliance table lists 1,500 to 5,000 watts. The spread comes from the size of the heating element, the heat setting and the age of the machine.
That range is a starting point. The number that matters for your house is on your dryer's rating label, and the number that matters for your bill is how long the element is actually on.
Where the watts go
Almost all of an electric dryer's power goes to the heating element. The drum motor, the blower and the controls use a small share by comparison.
| Dryer type | What uses electricity | Typical watts |
|---|---|---|
| Electric (vented) | Heating element, motor, blower, controls | about 1,800 – 5,000 W (Penn State) |
| Gas (vented) | Motor, blower, controls, igniter — gas supplies the heat | far lower; see the label |
| Heat pump (ventless) | Compressor, motor, fan, controls | uses around 70% less energy than a conventional dryer (ENERGY STAR) |
The element does not run at full power for the whole cycle. Once the drum reaches temperature, a thermostat cycles the element on and off, and sensor-dry cycles end the load when the clothes are dry. That is why an hour of drying uses less energy than the full rating times one hour.
Find the number for your dryer
Every dryer has a rating label, usually inside the door frame, on the back panel or in the owner's manual. On an electric dryer it lists the rating in watts or kilowatts at 240 volts, and often a second figure at 208 volts for buildings that supply that voltage. On a gas dryer, the label lists a much smaller electrical rating at 120 volts and the gas input separately.
Multiply kW by 1,000 for watts; the watts to kW calculator converts the other way. Treat the label figure as the maximum draw, not as what the dryer uses during a normal load.
kWh per load: watts × hours ÷ 1,000
Energy is power over time. To estimate kWh:
kWh = watts × hours ÷ 1,000
Arithmetic illustrations, not measurements of any product:
- A dryer averaging 3,000 watts for 45 minutes (0.75 hours): about 2.25 kWh
- A dryer averaging 4,000 watts for 1 hour: about 4 kWh
- A dryer averaging 2,000 watts for 40 minutes on low heat: about 1.3 kWh
Your load will differ with the cycle, the heat setting and how wet the clothes are going in. A washer with a faster final spin leaves less water for the dryer to remove. The watts to kWh calculator does the math for any wattage and time.
Running cost
Multiply kWh by the price on your bill. As an illustration at 16 cents per kWh:
- 1.3 kWh ≈ 21 cents
- 2.25 kWh ≈ 36 cents
- 4 kWh ≈ 64 cents
If your utility uses time-of-use pricing, the same load costs more during the peak than overnight or midday. ENERGY STAR points out that a dryer's delay-start feature can save money where time-of-use rates apply. Lower heat settings, sensor-dry cycles and a clean lint filter all shorten the time the element is on.
Amps and the 240-volt circuit
To convert watts to amps, divide by volts. Electric dryers run on 240 volts, so 3,000 W is 12.5 amps and 5,000 W about 20.8 amps. That is why an electric dryer sits on its own double-pole breaker. When an electrician calculates a home's total electrical load, the National Electrical Code counts a household dryer at 5,000 watts or its nameplate rating, whichever is larger.
The breaker, wire and receptacle come from the dryer's installation instructions and the code, and a licensed electrician sizes the circuit. How many amps a dryer uses covers the circuit side in detail, and the watts to amps calculator converts any wattage at 120 or 240 volts. For a 120-volt comparison from the kitchen, see how many amps a dishwasher uses.
Gas and heat pump dryers
A gas dryer uses natural gas or propane for heat. Its electrical draw is the motor, blower, controls and igniter, usually on a standard 120-volt outlet, so its electric use is a small fraction of an electric model's. It still needs a gas line and a vent to the outside.
A heat pump dryer heats the air with a compressor and reuses it in a closed loop. ENERGY STAR says certified heat pump dryers use around 70% less energy than conventional clothes dryers, and that all of them meet its Most Efficient criteria. Because the air is not vented outside, a heat pump dryer needs no dryer vent. It does need a drain for the condensed water, or a tank you empty after each load.
A dryer in a power outage
An electric dryer is one of the hardest loads to back up. It draws thousands of watts at 240 volts for the better part of an hour, which can be more energy than a refrigerator uses in a day. Whether a home battery can run it depends on the system's continuous output and stored energy, and whether the dryer circuit is on the backed-up panel.
Most homeowners set backup priorities the other way round: refrigerator, freezer, sump or well pump, furnace controls, internet and lights first, using a critical load panel to choose the circuits. The laundry can usually wait until the grid is back. The washing machine is a much smaller load, if clean clothes matter during a long outage.
The critical load panel planner checks whether a battery can carry the circuits you pick. Home battery and backup projects that Seamless Home coordinates start with that list. Get a free estimate to begin. Coverage is confirmed per service area rather than promised as blanket availability.
Frequently asked questions
How many watts does a dryer use?
An electric clothes dryer typically uses about 1,800 to 5,000 watts, according to Penn State's EGEE 102 appliance table. The rating label on your dryer gives the maximum for your model.
How many kWh does a dryer use per load?
Watts × hours ÷ 1,000. A dryer averaging 3,000 watts for 45 minutes uses about 2.25 kWh; one averaging 4,000 watts for an hour uses 4 kWh. Real loads vary with the cycle, the heat setting and how wet the clothes are.
How many amps does a dryer draw?
Divide watts by volts. Electric dryers run on 240 volts, so 3,000 watts is 12.5 amps and 5,000 watts about 20.8 amps. The breaker and wire size come from the dryer's installation instructions and the electrical code, not from this arithmetic.
Does a gas dryer use electricity?
Yes, but much less. A gas dryer burns gas for heat and uses electricity for the drum motor, fan, controls and igniter, usually from a standard 120-volt outlet. The rating label lists its electrical rating.
Do heat pump dryers use less electricity?
Yes. ENERGY STAR says certified heat pump dryers use around 70% less energy than conventional clothes dryers. They recirculate the air instead of venting it, so they need no exterior vent but do need a drain or a water tank that is emptied.
How much does it cost to run a dryer?
Multiply kWh by your electricity rate. As an illustration at 16 cents per kWh, a 2.25 kWh load costs about 36 cents and a 4 kWh load about 64 cents. If your utility uses time-of-use pricing, the same load costs less off-peak.
Can a home battery run an electric dryer during an outage?
Sometimes, but it is a large 240-volt load that can drain a battery quickly. Many homeowners leave the dryer off the backup circuits and run it once grid power returns.
