how many watts does a space heater use

Most home space heaters use around 1,500 watts on their highest setting, with common models ranging from about 750 to 1,500 watts , and some heavy‑duty units going up to roughly 1,800 watts.

Quick Scoop

Typical wattage range

• Many compact or “personal” space heaters draw about 750 watts on low and 1,500 watts on high.

• Overall, most residential electric space heaters fall in the 750–1,500 watt band, with higher-end models sometimes reaching about 1,800 watts.

What that means in practice

• A 1,500‑watt heater running for 1 hour uses about 1.5 kWh of electricity; at 8 hours a day, that’s roughly 12 kWh per day and about 84 kWh per week.

• Because of this relatively high draw, space heaters are considered medium to high power household appliances and can noticeably impact your electric bill if run for many hours daily.

Little story-style example

You plug in a 1,500‑watt heater next to your desk on a cold January evening and leave it on high for 4 hours. That single session uses about 6 kWh of electricity, which can add up quickly if you repeat it every day in winter.

TL;DR: When people ask “how many watts does a space heater use?” they’re usually talking about a 1,500‑watt unit, but expect anything from about 750 to 1,500 watts for most home heaters.
