The Mill SG1200WIFI convection heater - provides warmth and comfort in style 

Equipped with an advanced thermostat and a fan for extra heat distribution, the SG1200WIFI can quickly heat the entire room, while three heat settings let you choose the ideal temperature to keep your home lovely and warm. It can be used in rooms from 14 mto 18 m2. Please note that this heater is recommended to be used in well-ventilated areas. 

Aluminium heating element and built-in powerful fan

The Mill convection heater features an aluminium heating element that is well known for its capability to heat in no time and give off heat quicker than conventional radiators and fan heaters. The integrated fan helps provide rapid heat distribution on those extra wintry days and chilly nights. 

Encapsulated heating element helps minimise dry air 

The enclosed heating element inside the Mill oil-filled radiator provides a gentle heating source that helps minimise dry air in the room, creating a good indoor climate for people with allergies, respiratory issues and eye irritations.

Built for safe use, portability and quiet operation

Mill designed the convection heater with safety and ease of use in mind. It features a tip-over switch that turns the heater off automatically if it tips over. The overheating protection makes sure that the heater turns itself off if it gets too hot. The beautifully designed wide aluminium foot creates a premium look and provides extra stability. You will like this heater as it is lightweight and portable enough to be moved from room to room.

The Mill convection heater is extremely quiet and just perfect for bringing much-needed cosiness and warmth into a bedroom, conservatory, living room or home office. 

Automated temperature control and Wi-Fi connectivity

The new generation Mill SG1200WIFI is a Wi-Fi-enabled convection heater that gives you control of your heating wherever you are at the touch of a button on your smart device with the free Millheat app. The app allows you to control multiple heaters from the same interface, therefore enabling you to set different temperatures in all rooms to suit different people’s needs. You can control different locations and as many heaters as you want.

The heater's integrated wireless module removes the need for a hub or smart thermostat. It connects directly to your Wi-Fi network. 

The Mill heater features an advanced day/night program setting, which enables you to lower the room temperature when you are not at home, reducing up to 25% of electricity usage.  Thanks to the handy holiday setting, you can even make sure that your home is nice and warm to welcome you back.
