A smart plug for electric heaters allows you to control an existing heater through an app without replacing the heater itself. By connecting a compatible electric heater to a Mill WiFi Socket or Mill Smart WiFi Plug, you can adjust room temperatures remotely, create heating schedules and automate your heating according to your daily routine.
Unlike conventional smart plugs that simply turn appliances on and off, Mill’s smart heating plugs feature integrated temperature sensors, allowing them to regulate heating based on the room temperature.
Mill’s smart plugs connect your existing electric heater to the Mill app through WiFi.
The integrated temperature sensor measures the surrounding temperature and automatically switches the connected heater on or off to maintain your selected temperature.
For example, you can schedule your living room to reach 22°C before you arrive home and automatically lower the temperature while you’re away.
This provides smart thermostat functionality for compatible conventional heaters without requiring a new WiFi-enabled heater.
Mill WiFi Socket transforms compatible electric heaters into app-controlled heating devices.
With an integrated temperature sensor, you can manage room temperatures, create heating schedules and control your heater remotely through the Mill app.
Generation 3 also features an integrated humidity sensor, automatic power measurement, predictive heating and an open-window function that switches off the heater when an open window is detected.
Best for: Homeowners who want to upgrade compatible existing heaters with smart temperature control and automated heating schedules.
Mill Smart WiFi Plug offers intelligent temperature control with additional smart home integration possibilities.
Like the Mill WiFi Socket, it features integrated temperature and humidity sensors, app-based heating schedules and predictive heating functionality.
It also supports Matter, allowing integration with compatible smart home platforms such as Apple Home, Google Home and Amazon Alexa.
Best for: Those who want to make existing heaters smart while integrating heating control into a wider smart home system.
A smart plug does not make an electric heater produce more heat from the same amount of electricity. Instead, potential energy savings come from more precise temperature control and reduced unnecessary heating.
With the Mill app, you can lower temperatures automatically when rooms are not in use, schedule heating around your daily routine and adjust settings remotely.
Actual electricity savings depend on your previous heating habits, insulation, outdoor temperature and the heating schedules you choose.
Mill WiFi Socket and Mill Smart WiFi Plug support compatible electric heaters with a maximum power consumption of 2300W.
They are generally suitable for heaters with mechanical thermostats and electronic thermostats that automatically resume operation after a power interruption.
The heater must be approved for unattended operation and compatible with external power switching.
Mill smart plugs must not be used with heaters that require supervision, including the Mill Instant and Mill Compact fan heater ranges. They are also not intended for critical electrical equipment such as heat pumps, water heaters, underfloor heating systems or refrigerators.
Always check the heater’s user manual and the smart plug’s compatibility requirements before connecting a device.
By upgrading compatible existing heaters, Mill smart plugs provide a practical way to introduce smart heating control without replacing equipment that still works.
