The Mill Gentle Air OIL2000WIFI3 is a 2000W oil-filled radiator recommended for rooms of 24–28 m². It combines an enclosed radiator body with an aluminium foot and three selectable heat levels of 800W, 1200W and 2000W. The format is designed for quiet, stable room heating, while Mill Heat Boost Technology uses the closed shape to move warmed air through the room more effectively than a conventional open-fin layout.

WiFi and the Mill App provide remote temperature control and scheduling, with Bluetooth-assisted setup and Predictive Heating for scheduled target temperatures. Mill currently lists the model as Matter compatible and also supports Homey and Tibber integrations. Open Window Function responds to sudden temperature drops. Verified safety features include a tip-over switch, overheat protection, child safety lock and commercial lock. The supplier EAN should be checked before publication because current manufacturer/distributor data shows a different GTIN for this exact MPN.
