De’Longhi Dragon Digital Oil Filled Radiator Heater Review
The De’Longhi Dragon Digital Oil Filled Radiator Heater (model TRD40615E) is the top of the oil-filled radiator range, aimed at poorly insulated rooms where a fan heater struggles to hold a temperature. This review works from the published specification, the listed feature set, and the demand pattern around the model rather than any hands-off trial.
Setup and Controls: The 1500W Electric Space Heater
Setting up this oil-filled radiator heater takes minutes. The “Smart Snap” wheels come pre-attached, and the white floor-mounted cabinet needs only a level surface and an outlet. The adjustable digital thermostat allows a specific set point rather than a dial position, which is what separates this from budget column radiators.
What Stands Out
This is a convection and radiant combination rather than a pure radiator. De’Longhi specifies 25% more radiant surface than traditional heaters, achieved through the fin profile, which produces more even warmth and fewer cold spots. The thermal chimneys are the more interesting engineering detail: they channel air up through the fins, which increases output while keeping the external surface temperature lower, a real advantage in a household with children or pets.
The 24-hour programmable timer is the feature most owners use daily, since it can bring a room up to temperature before it is occupied and shut off afterwards. The ECO Plus feature adjusts power to the room’s demand rather than running flat out.
The Quirks
The clicking sound as the thermostat cycles on and off is the most commonly noted annoyance. It is not loud, but it is a distinct click in an otherwise silent appliance, which light sleepers notice. Weight is the other consideration: at 26.6 pounds this is a two-handed lift, and the wheels only help on level floors, not stairs.
How It Compares
Against the Dyson AM09 fan heater, the De’Longhi Dragon wins on silent running, since there is no fan blowing air across the room. It is also the better choice for allergy sufferers for the same reason: no fan means no dust circulation, unlike a Lasko ceramic heater. What it gives up is portability and speed, and it has no remote control where the Dyson does. The TRD40615EBK is essentially this radiator in a different finish, so compare current prices, and the EW7707CM ComforTemp is the simpler, cheaper option in the same family.
Is It Worth It?
It is not the cheapest heater available. What justifies the price is the safety set (thermal cut-off and child lock), the durable steel construction, and the fact that the diathermic oil reservoir never needs refilling, making it effectively maintenance-free. On running cost, note that a 1500W radiator draws 1500W like any other: the ECO Plus mode and timer save money by limiting how long it runs, not by generating more heat per watt.
The De’Longhi TRD40615E is a serious piece of winter equipment. The quirks are real, but for steady, silent, low-maintenance heat it is among the best-specified radiators available. Compare it with the rest of our electric space heater reviews before deciding.
Pros
- Exceptional Energy Efficiency: The heater’s ECO Plus feature optimizes power consumption, making it an excellent choice for reducing energy costs during those long winter months.
- Safe for Families: With its child lock, anti-freeze mode, and cooler surface temperatures due to the thermal chimneys, it’s ideal for households with kids and pets.
- Silent Operation: Unlike fan-based heaters, the De’Longhi Dragon operates quietly, with only minimal clicks during temperature adjustments.
- Durable Design: Constructed with rust-resistant metal and featuring a corrosion-resistant finish, this heater is built to last.
- Consistent Heating: Its 25% increased radiant surface ensures even and powerful heat distribution, making it a standout in its category.
Cons
- Hefty Weight: At 26.6 pounds, portability isn’t its strong suit, even with the built-in ergonomic handles and wheels.
- Lacks a Remote Control: Adjusting settings requires you to interact directly with the control panel, which might be inconvenient for some users.
- Clicking Noise: The sound of the heater cycling on and off is noticeable, which could be bothersome for light sleepers.
- Limited Heating Area: While effective in small to medium spaces, it struggles to heat larger, open areas efficiently.
- No Smart Connectivity: In an age of Wi-Fi-enabled devices, this heater doesn’t integrate with smart home systems.
