Our Verdict
This De'Longhi heater delivers 1500W of quiet, steady warmth. The oil-filled design uses no fan. Your air stays moist and free from stirred-up dust.
The built-in thermostat controls temperature automatically. You set your comfort level once. The heater maintains it without constant adjustment.
One major gap stands out at this price. This model has no tip-over protection. Most competing heaters in this range include that feature.
At $86.40, you pay for the De'Longhi brand and oil-filled design. You do not get a timer or remote control. Those features appear on cheaper models.
This heater works best in bedrooms and quiet spaces. It runs silently through the night. The anti-freeze function protects rooms at minimal power.
What We Like
- 1500W output delivers maximum standard electric heating power
- Oil-filled design runs completely silently with no fan
- Built-in thermostat automatically holds your chosen temperature
- Overheat protection shuts the unit off before it gets dangerously hot
- Anti-freeze function keeps rooms above freezing at minimal power draw
What Could Be Better
- No tip-over protection, a standard safety feature found on most competing heaters
- No timer, so you cannot schedule the heater to turn off automatically
- No remote control, requiring you to adjust settings directly at the unit
- Oil-filled design takes 15 to 30 minutes to reach full heat output
- Heating coverage of approximately 150 sq ft falls below the average for 1500W heaters
