"Heats the person, not the room" is the standard sales line for electric blankets — and it happens to be true. Understanding the actual numbers helps you choose the right product and helps your sales team answer energy-conscious customers.
How much power does a heated blanket use?
Typical wattage ranges (running at full power):
- Heated throws: 60–120 W
- Twin blankets: 60–100 W
- Full/Queen/King blankets: 100–200 W
- Heated mattress pads: 60–150 W
In practice, users rarely run at maximum all night — controllers cycle heat, and many use pre-heat then switch to a lower level or rely on auto shut-off. Real-world consumption is typically well below the rated wattage.
Heated blanket vs space heater
| Device | Typical wattage | What it heats |
|---|---|---|
| Electric blanket (king) | ~150–200 W | The person in bed |
| Electric throw | ~60–120 W | One person on the sofa |
| Space heater (room) | 1,000–2,000 W | The whole room, including empty space |
A 1,500 W space heater running all night uses roughly 10 times the electricity of a full-size heated blanket at its rated power — and the blanket's heat is applied exactly where it is needed. That is the core of the energy-saving story.
Using the numbers responsibly
Actual cost depends on local electricity rates, usage hours and thermostat behavior, so avoid publishing a single "cost per night" figure without context. A credible approach for product listings:
- State rated wattage clearly (e.g., "150 W")
- Mention pre-heat + auto shut-off as energy-saving features
- Compare against typical space heater wattage (1,000–2,000 W) rather than quoting absolute currency amounts
Energy-saving features to look for
- Pre-heat function — warm the bed before sleep, then sleep cool on low or off
- Auto shut-off timer — no forgotten overnight running
- Multi-level control — users drop to low levels after initial warm-up
- Dual-zone blankets — each side heats only as much as needed
For buyers, these features are genuine differentiators — and for brands, "heats the person, not the room" is a message that converts in an energy-conscious market. Ready to build your line? Talk to Haiyue Shengda about specs and sampling.
