How Much Electricity Do Home Appliances Use?

MegaDealShop Research Team Updated October 2026 4 min read

Quick Answer

The biggest home loads are heating, cooling, and water heating. Typical draw: central AC 3,000-4,000 W, space heater 1,500 W, electric water heater 4,000-4,500 W, clothes dryer 3,000-5,000 W, oven 2,000-5,000 W, fridge 100-400 W running, LED bulb 8-12 W, TV 50-150 W. Controlling the big three controls most of the bill.

How to Read the Numbers

Watts show instantaneous draw; kilowatt-hours show energy over time. A 100 W device running 10 hours and a 1,000 W device running 1 hour both use 1 kWh. Always pair wattage with hours to judge cost.

Heating and Cooling

Central AC typically draws 3,000-4,000 W while running; a window unit 500-1,500 W; a space heater about 1,500 W; a heat pump similar to AC. Because these run for long stretches, they usually top the usage list.

Water Heating and Laundry

An electric resistance water heater draws roughly 4,000-4,500 W while heating. A clothes dryer uses 3,000-5,000 W; a washing machine 500-1,500 W. Heat-pump water heaters and line drying cut these dramatically.

Kitchen and Everyday

Oven 2,000-5,000 W, microwave 600-1,500 W, dishwasher 1,200-2,400 W, coffee maker 900-1,500 W, fridge ~100-400 W running. Individually modest, but the fridge and freezer run around the clock.

Electronics and Lighting

TV 50-150 W, laptop 30-70 W, gaming console 90-200 W, LED bulb 8-12 W, incandescent 40-100 W. Phantom standby loads add up; switched strips help. LEDs remain the cheapest efficiency upgrade.

Frequently Asked Questions

What uses the most electricity at home?
Generally heating, cooling, and water heating, followed by large kitchen and laundry appliances.
Do small devices matter?
Yes when they run constantly (fridges) or in standby across many units. Individually they are minor.
