Mill PA700WIFI4 Smart WiFi Panel Heater for Efficient, Controllable Home Heating

Steady, efficient heat for rooms up to 12 m²:

The Mill PA700WIFI4 uses an X-aluminium heating element to distribute warmth evenly across the room while keeping the surface temperature at a maximum of 55 °C - safe to touch and comfortable to live with. At 700W it is suited to rooms of 9 to 12 m² such as a bedroom, home office or hobby room, and its slim 86 mm wall projection keeps it unobtrusive on any wall.

Mill PID Wattage Tech™ and Mill Predictive Heating™:

Mill PID Wattage Tech™ reduces power output once the set temperature is reached, keeping the room at a precise, stable temperature rather than cycling on and off at full power. Mill Predictive Heating™ learns how quickly your room warms up and starts the heater at the right time so the temperature is where you want it when you need it - without running longer than necessary.

Full smart home compatibility via the Mill App:

The heater connects over 2.4 GHz WiFi 6 and Bluetooth 5.2 (used for initial setup), and supports Matter, Zigbee 3.0, Amazon Alexa, Apple HomeKit, Google Home, Homey and Tibber. The Mill App for iOS and Android lets you set schedules, adjust temperature and monitor usage from anywhere. A Commercial Lock feature allows landlords and holiday home owners to set a maximum temperature cap on the heater.

Safe for bathrooms and family homes:

With an IPX4 water-resistance rating, the PA700WIFI4 is approved for installation in bathroom Zone 2. Built-in overheat protection, a child safety lock and Open Window Function - which detects a rapid temperature drop and pauses heating automatically - make it suitable for family use throughout the home.

Setup and Care

Getting Started:

Download the free Mill App on iOS or Android before switching the heater on. The app guides you through the initial Bluetooth 5.2 pairing process and connects the heater to your 2.4 GHz WiFi network in a few steps. Once connected, you can set schedules, adjust temperature and link to your preferred smart home platform.

Wall Mounting:

The wall mounting bracket and screws are included in the box. The heater can also be used freestanding if wall mounting is not preferred. When wall mounting in a bathroom, ensure installation is within Zone 2 and complies with local electrical regulations - consult a qualified electrician if in any doubt.

Smart Home Integration:

For Matter and Zigbee 3.0 integration, ensure your hub or controller supports these protocols before pairing. The heater also supports Local REST API and Open API for advanced home automation setups, giving you flexibility however your smart home is configured.

Keeping Your Heater in Good Condition:

Wipe the outer surface with a dry or lightly damp cloth - avoid abrasive cleaners or solvents on the steel front panel. Keep the area around the heater clear to allow air to circulate freely, and check that the power cord is undamaged before each heating season.
