To choose a portable heater, consider factors like heating capacity, energy efficiency, safety features, size, and your specific space requirements.
Portable heaters offer targeted warmth without cranking up your whole-home heating system. With various types, sizes, and safety features available, selecting the right model requires careful consideration of your specific needs.
Key Factors When Choosing A Portable Heater
1. Heating Technology
Different heater types use distinct warming methods:
| Type | Best For | Pros | Cons |
|---|---|---|---|
| Convection | Whole room heating | Even heat distribution, energy efficient | Slower warm-up |
| Radiant | Spot heating | Instant warmth, quiet operation | Limited range |
| Fan-forced | Quick air circulation | Fast heating, affordable | Can be noisy |
For garage or workshop use, consider a built-in gas heater if permanent installation is an option.
2. Room Size And Wattage
Match heater capacity to your space:
- 150 sq ft: 750-1000W
- 250 sq ft: 1500W
- 400+ sq ft: 2000W+
According to Energy.gov, properly sizing your heater prevents energy waste and improves efficiency.
3. Safety Features
Essential safety components include:
- Tip-over switch
- Overheat protection
- Cool-touch exterior
- UL certification
Specialty Portable Heaters
For Outdoor Use
Outdoor models like the Duraheat 360 indoor/outdoor propane heater feature weather-resistant construction and higher BTU output.
For Workspaces
Under-desk radiant heaters provide focused warmth without taking up floor space. The ViaAqua 200W quartz heater offers efficient spot heating for offices.
Energy Efficiency Considerations
While all electric heaters are 100% efficient at converting electricity to heat, some models distribute warmth more effectively:
- Oil-filled radiators retain heat longest
- Ceramic heaters provide quick warmth with good air circulation
- Infrared heaters lose less heat to air movement
The Consumer Reports buying guide recommends looking for energy-saving features like programmable thermostats and eco-modes.
Placement And Usage Tips
- Keep 3 feet clearance from flammable materials
- Place on hard, level surfaces only
- Plug directly into wall outlets (no extension cords)
- Use in well-ventilated areas
- Clean filters regularly for optimal performance
For large spaces, consider splitting heating needs between multiple smaller units rather than one oversized heater.
