Most clothes irons use about 800 to 2,000 watts while heating, with many household steam irons landing around 1,200 to 1,800 W.
For full system planning, use the WattSizing Calculator.
Quick Answer
Most irons draw about 800–2,000 W when the heating element is on. Like other thermostatically controlled heating appliances, they typically cycle, so the average draw during a session is often lower than the nameplate wattage.
Detailed Explanation
An iron is a high-wattage resistive load. It can pull a lot of power when it’s actively heating the soleplate, but once it reaches temperature it turns the element on and off to maintain heat.
What affects wattage most:
- Iron type: travel irons are usually lower wattage; full-size steam irons are higher.
- Heat setting: cotton/linen settings keep the plate hotter and can increase duty cycle.
- Steam bursts: the heater works harder to maintain temperature when you’re using more steam.

Watt Table
| Iron Type / Use Case | Typical Running Watts | Typical Starting Watts |
|---|---|---|
| Travel iron | 600 - 1,000 W | 650 - 1,050 W |
| Standard dry iron | 800 - 1,400 W | 850 - 1,500 W |
| Household steam iron | 1,200 - 1,800 W | 1,250 - 1,900 W |
| Heavy-duty / pro-style iron | 1,600 - 2,200 W | 1,700 - 2,300 W |
| Steam generator station (base + iron) | 1,800 - 2,800 W | 1,900 - 3,000 W |
Calculation Example
Example: A steam iron is rated 1,600 W. During a 30-minute session, it cycles and averages about 900 W.
- Session time: 0.5 hours
- kWh/session = (900 Ă— 0.5) / 1000 = 0.45 kWh
- At $0.16/kWh, cost per session is about $0.07

Tips to Reduce Power Usage
- Iron in batches so you only heat the iron once.
- Use the lowest temperature setting that still works for the fabric.
- If you use steam, keep the soleplate clean—better heat transfer can reduce time spent ironing.
FAQs
Does an iron have a big startup surge?
Not like a motor load. It ramps to its heating wattage quickly, but “startup” is usually close to its normal heating draw.
Why does my watt meter jump up and down?
The thermostat cycles the heating element to hold the target temperature. More steam or thicker fabric can increase how often it cycles.
Is a higher-watt iron always better?
Not always, but higher wattage can mean faster heat-up and better temperature recovery when using steam.
