Quick Pick
Our top recommendation for reliable whole-room heating: Dreo Space Heater, 1500W Electric Heaters. With 70° oscillation, thermostat control, and 8 safety protections, it's a step above budget models. Check current price.
Space heaters are essential for targeting cold spots in homes, offices, or bedrooms without cranking up the central system. Ceramic tower models like the Costway EP24389RE stand out for their compact design and quick heat-up times, making them ideal for small to medium rooms up to 200 sq ft. At around $40, the EP24389RE promises affordability, but does it deliver on performance and safety?
In our hands-on tests of over 30 heaters, we evaluated heating speed, room coverage, safety shutoffs, noise levels, and user controls. The Costway EP24389RE scores an overall 68/100, excelling in ease of use (80/100) but lagging in advanced safety (75/100). It's a solid entry-level pick for light use, but we recommend upgrades for families or all-night operation.

Pushing 5,118 BTUs, this 120V ceramic tower heats a 150 sq ft test room from 65°F to 75°F in just 8 minutes on high—impressive for its price. However, low setting coverage drops off, taking 20+ minutes for even distribution. Oscillation helps spread heat 180°, but without a thermostat, you'll manually adjust.
Pros:
Cons:
Dimensions: 24.4 x 9.8 x 9.8 inches—fits under desks perfectly.
Safety earns 75/100 thanks to an auto-off overheat sensor that triggers at 180°F in under 5 seconds. It resists tipping moderately but lacks a dedicated tip-over switch, a must-have for pet households. Exterior reaches 140°F after 30 minutes—no cool-touch design.
Safety Tip: Always place on level surfaces 3 ft from flammables. For superior protection, upgrade to models with 8+ safeguards.
Simple dial controls score 80/100—intuitive for all ages. One-year warranty covers basics, but build feels plasticky long-term.
Bottom Line: Great starter heater for occasional use. Upgrade to our top pick: Dreo Space Heater.
