Where this leaves you Twenty-five decibels, the quietest figure on this shelf by nine, with a published coverage range of 100 to 270 square feet and a child lock. DREO publishes three different noise figures across three heaters here, and this is the best of them.
What the maker puts in writing
As low as 25 dB
Covers 100 to 270 sq ft · 70° oscillation · 11.5 ft/s
The quietest figure on the shelf, from the only brand that publishes three
Four heaters here give a decibel number. Three of them are DREO: 25, 34 and 37.5. The fourth is 39.
Within one brand’s own range that spread is informative — it says the quiet is engineered rather than claimed — and this is the top of it.
A range, not a number
can easily cover areas of 100-270 sq ft.
Coverage depends on insulation, ceiling height and how cold it is outside, so a single square-foot figure is always a guess. Two other heaters on this shelf publish a flat 250; this one publishes a span, which is the more honest shape for the claim.

The good and the less good
Strengths
Twenty-five decibels, the quietest published figure on this shelf and nine below the next
Publishes a coverage range rather than a single number — 100 to 270 square feet — which is the honest way to state it
The only heater here to publish a tip-over angle: 45 degrees, rather than just "tip-over protection"
Compromises
Does not publish a wattage, where seven heaters on this shelf state 1,500 W
The most expensive DREO on this shelf, for the same 41-to-95 °F thermostat its cheaper siblings have

It is the maker’s figure for its quietest setting, and DREO publishes three different numbers across three heaters on this shelf — 25, 34 and 37.5 dB — which at least suggests they are measured rather than copied. Five heaters here publish nothing at all.
What does the 45-degree tip-over mean?
The angle at which the heater cuts power if it leans. Four heaters on this shelf claim tip-over protection; this is the only one that says at what angle it triggers.
Why is there no wattage?
The listing gives an airflow speed of 11.5 ft/s and a coverage range instead. Its two DREO siblings on this shelf both state 1,500 W, and so do five other heaters here, which is the practical ceiling for a household outlet.

2,000 W oil-filled radiator · 9 fins · safety thermostat
A 2,000 W oil-filled radiator with 9 fins, sold under De'Longhi's Radia S line. De'Longhi states a safety thermostat for overheat cutoff, a stepless temperature-and-power dial, its own 'Real Energy' gradual-heat control, and 360° castors with front and rear handles for moving it between rooms. Coverage is stated as up to 60 m (197 ft)³ on the German listing.
Best for: A room you want to heat steadily over hours rather than minutes, where the weight and slower warm-up of an oil-filled radiator are an acceptable trade for residual heat after it's switched off.
1,500 W PTC ceramic · 5–35 °C (41 to 95 °F) in ±1 °C steps · tip-over sensor
A 1,500 W PTC ceramic heater — Dreo's 'Hyperamics' system — with a thermostat adjustable from 5 to 35 °C (41 to 95 °F) in 1 °C steps, a tilt-detection tip-over sensor, overheat protection, and V0 flame-retardant housing. Dreo states 34 dB of operating noise from its brushless DC motor, and units sold since 5 September 2025 include a remote control.
Best for: A bedroom or home office where quiet running and a specific thermostat setpoint matter more than outright wattage.
