Space heaters efficiently warm entire rooms, while electric blankets provide targeted warmth for individuals, making them ideal for personal comfort in bed.
When winter chills hit, the debate between space heaters and electric blankets heats up. Both offer warmth but serve different needs. This guide compares costs, safety, and ideal use cases to help you choose wisely.
How They Work
Electric Blankets
Electric blankets contain thin heating wires woven into fabric. Modern versions feature:
- Adjustable heat settings (typically 10-20 levels)
- Auto-shutoff timers (1-12 hours)
- Machine-washable designs (most models)
- Dual controls for queen/king sizes
Space Heaters
Space heaters use various technologies:
| Type | How It Works | Best For |
|---|---|---|
| Ceramic | Heats ceramic plates with electricity | Small rooms |
| Infrared | Radiates heat to objects | Spot heating |
| Oil-filled | Heats contained oil | Quiet operation |
Cost Comparison
Electric Blankets
- Wattage: 60-200W (average 100W)
- Cost per night: $0.03-$0.10 (8 hours)
- Monthly cost: $1-$3 (daily use)
Space Heaters
- Wattage: 750-1500W (average 1000W)
- Cost per day: $0.60-$1.20 (8 hours)
- Monthly cost: $18-$36 (daily use)
According to McKenzie Electric, electric blankets use 80-90% less energy than space heaters for equivalent use time.
Safety Considerations
Electric Blanket Safety
- Replace every 10 years (wire degradation)
- Never fold while in use
- Look for UL certification
- Avoid use with infants/immobile persons
Space Heater Safety
- Keep 3 feet from flammables
- Choose models with tip-over switches
- Never leave unattended
- Plug directly into wall (no extension cords)
The University of Utah found electric blankets reduce fire risks by 85% compared to space heaters.
Best Use Cases
When to Choose an Electric Blanket
- Bedtime warmth
- Small apartments
- Supplemental heating
- People who sleep cold
When to Choose a Space Heater
- Heating small rooms
- Workspaces
- Bathrooms
- Areas with poor insulation
Advanced Options
Smart Electric Blankets
New models like the app-controlled blankets allow:
- Phone temperature adjustment
- Sleep tracking integration
- Voice control compatibility
Efficient Space Heaters
Modern units like propane models offer:
- Thermostatic controls
- Eco modes
- Oscillation features
Environmental Impact
Electric blankets generate about 0.2 lbs CO2 per night vs 2.5 lbs for space heaters (based on national average electricity sources). That’s equivalent to:
- Electric blanket: 0.4 miles driven
- Space heater: 5 miles driven
Long-Term Savings
Over 5 years (assuming 4 months annual use):
| Option | Energy Cost | CO2 Emissions |
|---|---|---|
| Electric Blanket | $20-$60 | 48 lbs |
| Space Heater | $360-$720 | 600 lbs |
