Our Top Picks
Space Heater Safety
- 3-foot rule: Keep heaters at least 3 feet from anything flammable (curtains, bedding, furniture)
- Never leave unattended: Turn off when leaving the room or going to sleep (unless oil-filled with timer)
- Plug directly into wall: Never use extension cords—they can overheat and cause fires
- Check for certifications: Look for UL or ETL listing on the label
Types of Space Heaters
Ceramic Heaters
Heat ceramic plates with electricity, then use a fan to distribute warm air. Fast heating, portable, affordable.
Oil-Filled Radiators
Heated oil circulates through fins, radiating warmth. Silent, retains heat, doesn't dry air.
Infrared Heaters
Heat objects directly (like the sun) rather than air. Instant warmth, energy-efficient for targeted heating.
Panel Heaters
Flat, wall-mounted heaters. Low-profile, safe around children, even heat distribution.

Space Heater Energy Costs
All space heaters are 100% efficient at converting electricity to heat. The difference is how they distribute that heat. Here's what running a 1500W heater costs:
Pro Tip: Space heaters work best for "zone heating"—warming the room you're in while keeping the rest of the house cooler. This can save money vs. heating your entire home.
