Things to Consider Before Buying a Large Electric Space Heater
Room Size
Always check a heater’s effective square footage. Smaller units (like compact ceramics or oil-filled radiators) may only handle 150–250 sq. ft., while infrared models like Dr. Infrared can reach 1000 sq. ft.
Heating Type

Noise Level
Fan-driven ceramic heaters may hum or whir, while oil-filled and infrared heaters are nearly silent. For bedrooms or offices, prioritize models under 40 dB.

Safety Features
Key features include:
- Tip-over shutoff
- Overheat protection

Remote and Smart Features
