How much electricity does a 1000W Dry Iron consume per month in India?

A 1000W dry iron (operating at ~45% thermostatic duty cycle) used for 30 minutes per session, 12 sessions per month, consumes only ~2.70 kWh (Units) of electricity per month (~₹20/month at ₹7.50/unit, costing ~₹1.69 per ironing session).

Does an electric iron draw its full rated power continuously?

No. Electric irons use a thermostatic control that automatically turns the heating element on and off once the soleplate reaches the set temperature. Dry irons operate at ~45% active duty cycle, while steam irons operate at ~50-55% duty cycle.

Which consumes more electricity: Dry Iron or Steam Iron?

Steam irons consume 40% to 80% more electricity than dry irons because they require higher rated wattage (1400W–2000W vs 750W–1000W) to continuously vaporize water into steam.

What standards govern electric irons in India?

Electric irons in India are tested under IS 302-2-3:2007 and IEC 60311 safety and performance standards.

Thermostatic Energy Cutoff Disclosure

Your 1000W iron does NOT draw power continuously! Thanks to its internal thermostat, the heating element is active only 45% of the time (450W average effective power draw).

How Electric Iron Power Consumption is Measured

Power consumption is calculated by factoring the thermostatic duty cycle (45% for dry irons, 50-55% for steam irons) under IS 302-2-3 standards.

Effective Heating Power (Watts) = Rated Power Watts × Thermostat Duty Cycle %

Per-Session kWh = (Rated Watts × Session Hours × Duty Cycle %) ÷ 1000

Monthly Bill (₹) = Per-Session kWh × Sessions/Month × Electricity Tariff Rate

Worked Example (Bajaj 1000W Dry Iron, 30 mins, 12 sessions/mo): 0.225 kWh/session = 2.70 Units/month = ₹20.25/month at ₹7.50/unit!
