De’Longhi Dragon Digital Full Room Radiant Heater TRD40615EBK-6A, Black review

The De’Longhi TRD40615EBK-6A is the black, digital six-fin radiator listed under SKU 0110838316. Its U.S. product page specifies 120 V/60 Hz, a 1,500-watt maximum and three heat settings. It describes a digital display, ECO operation, a 24-hour timer and child lock. This is not the same identity as the grey TRD40615T-6A, despite similar fins and a related Dragon name, and it is not interchangeable with the white TRD40615E-6A simply because the model strings share a prefix.

What the digital controls offer

A visible display and an ECO setting give this radiator a more electronic control experience than the mechanical TRD40615T. De’Longhi’s product page also states a 24-hour timer and a child-lock function. The page’s marketing description, however, calls the heater “TRD40615EL” in one paragraph even while the title, URL, black finish swatch and SKU identify TRD40615EBK-6A. I retain the exact page identity and document that mismatch rather than silently treating it as the same manual configuration as a TRD40615E or TRD40615EL.

The exact black configuration’s support bridge did not provide a matching U.S. instruction manual in the evidence reviewed for this profile. The timer’s semantics are therefore not established: a 24-hour timer label alone does not tell us whether it supports a delayed start, an automatic shutoff or both. I do not fill those questionnaire fields as confirmed. The same applies to button-lock behavior details, thermostat range, anti-freeze sequence and placement restrictions where the page does not spell them out.

Fanless radiator, not a quiet fan heater

The model page describes an oil-filled radiator and says that there is no fan to stir dust. That is a useful distinction from ceramic towers: it provides heat without a forced air stream and has no fan-only ventilation mode. Its manufacturer-listed three heat settings can satisfy an at-least-three-level need, while a requirement for four distinct stages should exclude it. The 1,500-watt rating is the maximum input; it does not determine how warm a particular room will feel.

The page reports a 2.15 m² (about 23.2-square-foot) working-capacity figure. Treat that as a manufacturer-stated data point, not independent proof of room coverage. Its listed body dimensions are 10.3 × 16.4 × 26.1 inches with no axis labels, so use the actual product documentation or measurements for a tight spot. The heater is a caster-mounted radiator weighing 25.61 pounds; rolling it is not the same as lifting it over steps or storing it in a narrow closet.

Choosing it over a close variant

The white TRD40615E-6A also has six fins and an electronic control layout, but its product-page title, SKU 0110838317 and model-specific support listing tie it to a separately documented English manual. That manual confirms a three-level temperature control, anti-freeze operation and a timer that can delay starting or stop a running heater, with a 0.5–24-hour range. I have not borrowed those details for the black EBK. A shopper who needs verified timer behavior should compare the exact white E model rather than assume that a finish change carries the same tested instructions.

The older TRD40615T-6A is another distinct choice: its page says mechanical controls and lists a programmable timer, but its accessible linked manual also mismatched. So neither neighboring model closes the EBK’s evidence gap. This exact-model discipline matters more than assuming that the radiator family shares a single control board or safety manual.

Fit and limits

Consider this radiator when you want fanless heat, digital controls, an ECO claim and an advertised timer, and you can verify the missing exact operating instructions before using any special schedule or placement. Do not shortlist it as a fan-only heater, app-connected product or confirmed delayed-start model. The product page lists a safety thermostat and thermal cutoff; these protections do not establish bathroom approval, outdoor use, extension-cord permission or unattended operation. Keep those answers unknown until the correct model-specific instructions are available.
