Our Verdict
This heater runs completely silent. Oil absorbs heat and releases it slowly and steadily. No fan means zero noise while you sleep.
You get three safety features built in. Tip-over protection, overheat shutoff, and child lock are all included. These features make it one of the safest options for a bedroom.
The 24-hour digital timer does your planning for you. Set it to warm your room before you wake. The ECO mode then cycles on and off to save power.
This heater covers about 150 square feet best. It has no oscillation to push heat around the room. Larger or open-plan spaces will warm more slowly.
The price is $89.99. That costs more than basic heaters, but you get silent oil heat and a full safety suite. De'Longhi builds this model for long overnight sessions.
What We Like
- Runs completely silent with no fan, so it never disturbs sleep.
- Delivers full 1500W of heat power for small to medium rooms.
- 24-hour digital timer lets you schedule heat on and off automatically.
- ECO mode cuts energy waste by cycling power to hold your target temperature.
- Includes tip-over protection, overheat shutoff, and child lock all in one unit.
What Could Be Better
- No remote control means you must walk to the unit to change any setting.
- No oscillation feature, so heat spreads slowly without a fan to circulate it.
- Estimated coverage of around 150 sq ft is below the 300 sq ft average for 1500W heaters.
- No Wi-Fi or smart home connectivity, so you cannot control it with an app or voice assistant.
- At $89.99, it costs more than the $40 budget threshold for entry-level space heaters.
