Product details

Mill Invisible Wifi Electric Panel Heaters Generation 4 are equipped with the latest energy-efficient technology packaged in a minimalist Scandinavian design. They owe their elegance to soft, rounded corners and a gently curved front that blends almost invisibly into the wall. These award-winning heaters provide comfortable ambient heat for everyone in the room, are silent, have a low surface temperature and are safe when left unattended and overnight.
