Mill WiFi Portable Heater 1200W White | CO1200WIFI3
Portable 1200W smart convection heating with Mill App control, predictive scheduling and a quiet X-aluminium heating element.
The Mill CO1200WIFI3 is a 1200W portable convection heater designed for rooms under 18 m². Its white steel front and aluminium foot give it a clean, freestanding format that can be moved between a bedroom, living room or home office as extra heat is needed. The X-aluminium heating element is designed for fast, even heat distribution, while the LED display keeps local settings easy to read.
WiFi and the Mill App add remote temperature control, weekly scheduling and energy-use oversight. Mill Predictive Heating can learn how quickly a room warms and cools so the heater can start at the right time for a scheduled target, while Open Window Function reacts to sudden temperature drops. Silent operation suits everyday living, and verified safety features include overheat protection, a tip-over switch, child safety lock and commercial lock.
