Are you hesitant to try smart gadgets, worried they’ll make things more complicated? Don’t worry! Mill is introducing its user-friendly WiFi heaters, featuring cutting-edge PID technology to enhance comfort and save energy with ease.
Heating makes up over 60% of a household’s electricity use. Smart heaters can reduce this by up to 32%! With Mill WiFi heaters, you gain complete control over your heating and energy consumption directly from your smartphone. The Mill app allows you to set temperature schedules that align with your daily routine and manage multiple heaters or households. Whether you’re at home or away, you can effortlessly monitor and adjust your home’s temperature, ensuring efficient energy use. Mill WiFi heaters are more than just another smart gadget—they’re a practical solution to reduce electricity waste and benefit both you and the environment.
Mill WiFi Panel Heaters make it simpler than ever to achieve both everyday comfort and energy savings. Featuring advanced software and hardware upgrades, these heaters offer improved device connectivity, enhanced safety features, and technical functionalities like OTA updates and Local Res API. With these innovations, Mill WiFi heaters deliver the following benefits:
PID Control
Mill WiFi Generation 3 panel heaters are the first to incorporate PID control technology, a revolutionary feature that makes achieving consistent room temperatures easier than ever. This system ensures stable heating by adjusting power levels gradually when the desired temperature is reached, rather than switching off entirely. With Proportional – Integrated – Derivative (PID) control, Mill heaters maintain a steady, reliable temperature while maximizing energy efficiency, providing you with comfort without the hassle.

Predictive Heating
Thanks to personalized settings in the Mill app, our heaters can predict when to start heating to achieve your ideal room temperature. This feature, known as predictive heating, allows Mill heaters to adjust and regulate temperatures automatically, ensuring your home is always at the perfect level of comfort. For instance, if you prefer a 23°C temperature when you return from work at 4 PM, simply set this in the Mill app, and the heater will take care of the rest, ensuring your home is warm and welcoming when you arrive.

Mill WiFi panel heaters learn how fast the room goes up and down in temperature over time, a function which helps avoid guessing and unnecessary power consumption. User settings can also be optimized in accordance to fluctuating electricity prices, as the app can be integrated with other programs. Our Generation 3 models are designed with improved WiFi connectivity which allows for an even easier automatic Bluetooth connection to your WiFi-network, regardless if your router prefers 2.4GHz or 5 GHz.
Scandinavian Design
Mill panel heaters come in two sleek, minimalist designs: Invisible and Glass. The Mill Invisible heaters feature soft, rounded edges and a gently curved steel front, seamlessly blending into your wall, giving the impression of invisibility. The Mill Glass heaters offer an exclusive, contemporary glass front, adding an elegant touch to any modern home. Both series are now available in black, making them the perfect fit for homes with a darker color palette, maintaining the perfect balance of style and functionality.
