Description
Mill designed the Invisible range in Norway to disappear into a modern interior, and the 250W model is the smallest and neatest of them. The steel front has no visible grille, the corners are rounded, and the white finish suits tiles and painted walls alike.
Controls are on the heater itself: an on/off switch, plus and minus buttons and a function key, with no app or Wi-Fi to set up. Its ecodesign data sheet gives a seasonal space heating efficiency of 43.2 percent with electronic room temperature control and open-window detection.
