Electric Blanket Vs Heating The Whole Room
Assumptions: 100W electric blanket for 2 hours versus 2,000W heater for 2 hours.
| Scenario | Electric blanket | Room heater | Likely better choice |
|---|---|---|---|
| Two hours | 5p | 99p | Electric blanket |
| Room comfort | Bed only | Whole room | Room heater |
| Damp control | No | Some warmth | Depends |
Cost comparison
The cost difference is large because an electric blanket targets a person rather than heating air in a room.
When each option wins
A room heater may still be necessary if the room is cold, damp or occupied for active tasks.
What can change the result
Use safe, modern blankets and follow washing and overnight-use guidance.
