The Dreo Atom 316 is a compact 1500W ceramic space heater with a PTC element and a heat funnel that Dreo says pushes warmth up to 200% farther than standard models. It runs at a claimed 34dB thanks to a brushless DC motor, and it holds a set temperature from 5 to 35°C in 1°C steps. It offers Power Heat, ECO and Fan Only modes with a 12-hour timer, plus V0 flame-retardant materials, tilt detection and overheat protection. It suits desk, bedroom and small-room use where noise matters more than heating a whole floor; against larger tower and oil-filled heaters it trades raw room coverage for quiet, precise control.
