Mill GL1200WIFI3 is a glass panel heater with an effect of 1200 Watt and suitable for rooms to max 18 m2. This model is a fully WiFi integrated panel heater, where the heater can be controlled with a touch of a button on our Millheat App. By using the App you can control different locations (home, cabins etc) and as many heaters as you want.

Generation 3
The Mill GL12000WIFI3 is a generation 3 model with many improvements in hardware and software compared to previous generation models such as:
• Super easy connection with Bluetooth allows it to automatically connect to your Wi-Fi network, no matter what type of router you have.
• The first and only heater with a PID (Proportional Integral Derivative) thermostat. When the desired temperature is reached, the heater will maintain this temperature by reducing the power level. This means more stable heating with less temperature fluctuations.
• Predictive heating – The panel heater heats the room so that the desired temperature is reached at a specific time. The panel heater has an advanced algorithm that allows it to learn how fast/slow the temperature in the room is going up/down. That way, it knows when to start heating to reach the desired temperature at the time you have scheduled in the app.

Integrated WIFI
The panel heater has an integrated WiFi module. This means no hub is needed or the thermostat changes. The heater connects directly to your WiFi network. Make sure your WiFi router has enough capacity for the number of active devices connected to your home network.



Scandinavia, known for its long winters and cool climate prefers convection heating; cold air is heated as it goes through the heating element, the hot air increases in volume and rise, making room for new cold air to come through, efficiently heating up the room.


Mill Wifi

The Millheat app gives you freedom to control your heaters from anywhere in the world, at a touch of a button. Just tell the app your normal schedule and it will adjust the temperature automatically for you, making your life easy and comfortable.

The app is built in a way such that each heater that is installed will be connected to a house and a specific room (where a room can consist of one or several heaters), or as independent heaters that can be moved between different rooms.

  • Control all your heaters situated in multiple locations (home, cabins etc), all inside the Millheat app. You can control all your heaters via the same user, regardless of where the heaters are situated
  • Set up weekly programs with different pore-defined modes (Comfort, Sleep, Away and OFF)
  • Set individual temperature for 3 different modes in each room
  • Override the set programs for the whole house, a specific room or a specific heater. There is no need to edit your program if you get home earlier than normal one day)
  • Control your heater independently by not assigning it to a specific room and program. This gives you the freedom to move the heater between rooms, according to your needs.
  • Enable advanced away mode for saving energy while you are away. The app will automatically increase the temperature in your house before you get back home
  • Share your house with other family members, making control easy
  • “Open window” function that automatically turns off the ehater if the temperature sensors registeres a sudden fall in the temperature. The heater will start heating again automatically after 10 minutes.

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.
