Our Verdict
The COSTWAY radiator delivers 1500W across 300 square feet. It runs below 35dB, so it won't disturb sleep or concentration. Three settings let you dial in 600W, 900W, or full 1500W.
The built-in thermostat holds your room at your chosen temperature. This cuts energy waste compared to heaters that run at full power continuously. The 300ml humidification box adds moisture for up to 6 hours per fill.
This heater skips features many competitors include at this price. No timer means you cannot schedule it to turn off at night. No remote control means you must walk to the unit for every adjustment.
At $116.99, you pay a premium over basic 1500W oil-filled heaters. You get the humidification box and dual heating tube design in return. Budget buyers can find simpler oil-filled models for $60 to $75.
What We Like
- Three heat settings (600W, 900W, 1500W) let you match power to your room size and comfort level.
- Built-in thermostat holds your room at the temperature you set, reducing energy waste automatically.
- Operates below 35dB, quieter than most fan-based heaters, so it won't disturb sleep or work.
- Dual U-shaped heating tubes and 7 fins cover up to 300 square feet with no assembly needed.
- Includes a 300ml humidification box on the back that adds moisture to dry air for up to 6 hours.
What Could Be Better
- Tip-over protection is not confirmed in the product specifications, a meaningful safety gap for active households.
- No timer function means you cannot schedule the heater to turn off automatically at night or after a set period.
- No remote control requires you to walk to the unit every time you want to change a setting.
- No oscillation, so heat spreads only through natural convection from the fins with no active air distribution.
- At $116.99, this heater costs significantly more than comparable 1500W oil-filled models available for under $70.

Frequently Asked Questions
Common questions about COSTWAY Oil Filled Radiator Heater, 1500W Portable Space Heater with 3 Heat Setting, Built-in Thermostat and Humidification Box, Energy-Saving Quiet Electric Heater for Home Office Indoor (Black)
How large a room can this heater warm?
The manufacturer rates this heater for spaces up to 300 square feet. That covers a medium bedroom, a home office, or a small to mid-sized living room.
Is this heater noisy?
No. Oil-filled radiators heat through convection, not a fan. This model runs below 35dB, which is quieter than a quiet library.
Can I set this heater to turn off on its own?
The thermostat will reduce output once your set temperature is reached, but there is no timer. You cannot schedule a full shutoff at a specific time.
Does this heater have overheat protection?
Yes. The heater includes overheat protection that shuts the unit off if internal temperatures get too high. It also carries ETL certification for added safety assurance.
How does the humidification box work?
The 300ml box sits on the back of the heater. You fill it with water and the heat from the unit causes the water to evaporate, adding moisture to the air for up to 6 hours.
