Our Verdict
This COSTWAY heater works best in small rooms under 120 sq ft. Its oil-filled design produces heat silently with no fan noise. That makes it a solid pick for a quiet bedroom or personal office.
The 700W output is below average for the space heater category. Most heaters at this price point deliver 1000W or more. Your room will take longer to warm up as a result.
It holds ETL certification and shuts off automatically if it overheats. But it does not have tip-over protection. Place it on a flat, stable surface away from high-traffic areas.
The adjustable thermostat lets you pick your comfort level and walk away. The heater maintains that temperature on its own. This keeps your energy use steady without constant adjustments.
At $59.99, you get quiet, simple heating without advanced controls. There is no timer, remote, or Wi-Fi. It fits your needs if silent, basic warmth is what you want.
What We Like
- Runs with no fan, so it makes virtually zero noise while heating your room
- ETL certified with automatic overheat shut-off for proven safety compliance
- Compact 12 x 5.5 x 15 inch body with a built-in carry handle for easy transport
- Adjustable thermostat knob lets you set and hold your preferred temperature
- 360-degree radiant heat warms your space evenly from all sides
What Could Be Better
- No tip-over protection, a safety feature most competing heaters at this price include
- 700W is below the 1000 to 1500W output standard for heaters in this price range
- Covers only 120 sq ft while many competitors at $60 cover 200 to 300 sq ft
- No timer function means you must manually turn the heater on and off each time
- No remote control requires you to adjust all settings by hand directly on the unit
