Key Features & Performance
Silent Heating Technology
DeLonghi’s proprietary quiet system reduces operational noise by half compared to standard ceramic heaters. Independent tests show it operates at just 45 decibels on low setting – quieter than a normal conversation (60 dB). The silent function works best on power level 1, creating minimal disturbance during sleep or work.
Advanced Ceramic Heating Element
The PTC ceramic heating system provides:
- Fast heat-up in under 60 seconds
- Even heat distribution through 70° oscillation
- Self-regulating temperature control
Unlike traditional radiator heaters, the ceramic element maintains consistent warmth without drying out the air.
Smart Energy Efficiency
The ECO Plus mode automatically:
- Adjusts power between 750W-1500W
- Maintains room temperature within ±1°F
- Reduces energy consumption by up to 40%
