Mill Invisible WiFi panel heaters gives you the best of both worlds. Innovative technology that helps you reduce your electricity consumption, combined with Scandinavian design that blends in with to your interior.

In the Mill App, you can program the temperature to automatically adjust to your daily routines, which ensures everyday comfort and saves you from unnecessary expenses and electricity usage. Mill WiFi panel heaters are equipped with unique PID technology that provides a more even temperature and reduced power consumption. When the desired temperature is reached, the heater will maintain this temperature by lowering the power level, which provides a more stable heating with smaller temperature fluctuations than traditional heaters. The heater also come with Predictive Heating, which is machine learning that provides precise temperature control and optimal comfort. Mill WiFi panel ovens are easily connected to WiFi via Bluetooth, regardless of the type of router you have. Mill Invisible won the Red Dot Design Award in 2022 for its minimalist and elegant design. With its soft, rounded edges and slightly curved front, the panel oven flows as one with the wall. Approved for use in bathrooms in zone 2 (IPx4). Feet for this model is available as accessory if you lack wall space or simply want a more flexible usage where you can move the heater around.


Mill Generation 3 WiFi offers new and revolutionary features. An upgrade of both hardware and software has enabled us to offer the following new benefits:

  • First panel heater with PID control heating technology. When the desired temperature is reached, the heater will maintain this temperature by lowering the power level. Meaning more stable heating with less fluctuation in temperature.
  • Predictive heating – the panel heater will heat the room so that the desired temperature is reached at a specific time. The heater learns how fast/slow the room goes up/down in temperature over time. That way, it will know when to start heating to achieve your desired temperature at the time you have scheduled in the app.
  • New WiFi chip that allows super easy connection with Bluetooth that automatically connects the device to your WiFi-network, regardless of the type of router you have.
  • 100% silent operation due to silicon control – no clicking sound when the temperature goes up and down.
  • Child safety lock – for safe usage.
  • Commercial lock for landlords.
  • Open window function that switches off the heater automatically when a window is opened.
  • Possibility to let Mill Sense override the heater´s temperature sensor – allowing more precise temperature control.
  • OTA (Over the Air) updates allowing new exciting features to be added to the software.
