COSTWAY 700W Oil Filled Radiator Heater — Is It Worth It for Bedroom Use in 2026?
A quiet, low-cost oil radiator for small rooms, but the absent tip-over protection and below-average 700W output hold it back from competing heaters.

Our Verdict
This COSTWAY radiator runs completely silent. No fan means zero noise, day or night.
The 700W draw is a real advantage for energy bills. It costs roughly half as much to run as a standard 1500W heater each season.
The thermostat shuts the unit off automatically when your room warms up. You do not need to monitor it or adjust anything manually.
The missing tip-over protection is the biggest concern here. Most oil radiators at this price include it as a standard built-in feature.
This unit fits small bedrooms and offices under 150 sq ft well. Do not expect it to heat a living room or open-plan space.
What We Like
- Completely silent operation with no fan or blower noise at any wattage setting.
- Thermostat auto-shuts off when your room hits the target temperature, saving energy.
- 700W uses less than half the electricity of a standard 1500W heater, lowering your bill.
- Overheat protection shuts the unit off automatically if internal temps get too high.
- ETL certified to North American safety standards, confirming independent third-party testing.
What Could Be Better
- No tip-over protection, a safety feature included on most competing oil-filled radiators.
- 700W output is well below the 1500W category average, limiting you to spaces under 150 sq ft.
- No timer to schedule heating cycles or set an automatic shut-off time.
- No remote control, so you must walk to the unit to change the thermostat setting.
- No oscillation or fan assist, so heat spreads slowly and only in one direction.

Frequently Asked Questions
Common questions about COSTWAY Oil Filled Radiator Heater, 700W Portable Space Heater with Adjustable Thermostat, Overheat Protection, Electric Heater for Bedroom, Indoor use
How large of a room can this heater warm?
At 700W and roughly 2,388 BTU, this heater works best in rooms up to about 150 sq ft. That covers a small bedroom or personal office.
Is this heater quiet enough to use while sleeping?
Yes. Oil radiators heat by convection with no internal fan, so this unit makes no noise while running. It will not disturb your sleep.
Does this heater shut off if it tips over?
No. This model does not include tip-over protection. Place it on a flat, stable surface and keep it away from high-traffic areas.
How much will this heater add to my electricity bill?
Running 8 hours daily for a 6-month heating season at 700W uses about 1,008 kWh. At the U.S. average rate of $0.15 per kWh, that is roughly $150 per year.
Can I set a timer so it turns off automatically at night?
No. This heater does not have a built-in timer. You would need an external plug-in timer outlet to schedule automatic shut-off.
