Quick Pick
Our Top Pick: Dreo Space Heater, 1500W Electric Heaters for Indoor Use (Check it out here)
With 70° oscillation, 8 safety protections, and a thermostat, this Dreo model heats large rooms evenly and safely. Perfect upgrade from budget options like the Costway.
Space heaters are essential for chilly offices, bedrooms, or garages, delivering targeted warmth without cranking up your central heating bills. The Costway EP25390US-BK, a portable 1500W model priced around $49, promises quick heating with features like oscillation and remote control. In our Review Atlas lab tests, it earned an overall score of 67/100—solid for budget buyers but outpaced by premium picks in safety and even distribution.
We evaluated it on heating performance (68/100), convenience (71/100), and safety (62/100), simulating real-world use in a 200 sq ft room. It raised temps by 15°F in one hour, but noise hit 52 dB (like a quiet conversation). Read on for in-depth results, a comparison table, pros/cons, and our top recommendations to keep you cozy this winter.

The Costway EP25390US-BK excels in rapid warm-up, boosting room temperature by 15°F within 60 minutes on high. Its 1500W ceramic element distributes heat evenly via 70° oscillation, covering up to 200 sq ft effectively. Multiple settings (low/medium/high) let you dial in comfort, and it transitions smoothly from heat to fan mode for year-round use.
However, in extended tests (2+ hours), it struggled with sustained evenness in corners, dropping 3-4°F farther from the unit compared to vortex-style competitors.
Scoring 71/100 here, this heater shines with user-friendly controls:
Setup takes seconds—just plug in and select mode. Oscillation is smooth and quiet, minimizing drafts.
At 62/100, safety is its weak spot. It has tip-over shutoff (activates in <2 seconds) and overheat protection (cuts off above 176°F), but lacks advanced features like cool-touch exterior or ALCI plugs. In our drop tests, it recovered quickly but emitted a faint plastic smell initially. Always place on flat surfaces away from flammables.
