What to know about De'Longhi Dragon Digital TRD40615E / TRD40615EBK
Why it stands out
Why we like it
It has thermal cut-off, a tip-over switch and a 3-year warranty, and the sealed oil reservoir never needs refilling. With no blower, it does not push dust around the room.
What to know
Score breakdown
Independent noise results (CR noise score, measured dB from Bob Vila, Tom's Guide and Reviewed) count above manufacturer dB claims. Fanless designs, low-speed or ECO operation, and no harsh clicking or beeping all help.
Tip-over and overheat shutoff, ETL/UL listing, hot-surface and exhaust temperatures (CR), child lock, and the brand's recall history.
How quickly and evenly the heater warms a typical 150–250 sq ft bedroom in independent tests.
Thermostat precision (digital vs. mechanical), sleep/auto-off timer, remote, display brightness, size and weight, and how easy it is to place 3 ft from bedding.
Whether a fan stirs up dust, first-use odors, flame-retardant (V-0) housings, filters, and repairability and warranty length.
Street price relative to performance, safety and warranty.
