DeLonghi oil filled radiator heaters provide efficient, quiet heating for medium-sized rooms. These units stand out for their durable construction, advanced safety features, and innovative heat distribution technology. While they take slightly longer to warm up than some alternatives, they maintain consistent warmth without drying the air.
Key Features and Benefits
Heating Performance
The DeLonghi TRD50615E model delivers 1500 watts (5120 BTU) of heating power across three settings. Its unique design provides 75% more radiant surface area than standard oil heaters, improving heat transfer efficiency. The convection heating effect helps distribute warmth faster throughout the room.
Unlike fan heaters that can dry the air, this radiator maintains humidity levels while heating. This makes it ideal for people with allergies or respiratory sensitivities. The sealed diathermic oil reservoir never requires refilling and provides lasting heat retention.
Energy Efficiency
DeLonghi’s ECO Plus function automatically adjusts power settings to maintain optimal comfort while conserving energy. The digital thermostat allows precise temperature control, preventing energy waste. According to our oil heater energy usage guide, these units can be more cost-effective than central heating for single-room use.
Safety Features
- Thermal cut-off prevents overheating
- Tip-over switch automatically shuts off if knocked over

Real-World Performance
Heating Speed
While oil-filled radiators take longer to reach full temperature than fan heaters, the DeLonghi models heat up relatively quickly thanks to their convection-enhanced design. Most users report noticeable warmth within 15-20 minutes in medium-sized rooms (150-250 sq ft).
Noise Level
These heaters operate silently with no fan noise, making them ideal for bedrooms and offices. The only sound is occasional quiet clicking from the thermostat adjusting.
Portability
SmartSnap wheels and ergonomic handles make moving between rooms effortless. At 25-30 lbs, the units are substantial but manageable. The compact design fits well in corners and against walls.
Comparison to Other Heaters
Oil-Filled vs. Ceramic Heaters
Compared to ceramic space heaters, DeLonghi oil radiators provide more consistent, even heat but take longer to warm up. They’re better for prolonged use in stationary locations rather than quick spot heating.
Against Generic Brands
While generic oil heaters may cost less, DeLonghi’s build quality and safety features justify the premium price. The sealed oil reservoir and steel construction ensure longevity that cheaper models often lack.
Maintenance and Troubleshooting
Care Instructions
These heaters require minimal maintenance:
- Wipe exterior with dry cloth
- Keep vents unobstructed
- Store upright when not in use
Common Issues
If your oil-filled radiator isn’t heating properly, check the power connection and thermostat settings. The unit may need time to warm up if recently turned on.
Who Should Buy This Heater?
The DeLonghi oil filled radiator excels for:
- Bedrooms and living rooms
- People sensitive to dry air
- Quiet environments
- Allergy sufferers
- Supplemental heating in well-insulated spaces
According to Consumer Reports, oil-filled radiators are among the safest space heater options when used properly. DeLonghi’s models exceed basic safety standards with multiple protection features.
For larger spaces or faster heating needs, consider pairing with a vented gas heater for more powerful warmth. However, the DeLonghi oil radiator provides an excellent balance of safety, efficiency, and comfort for most residential applications.
