The Mill SG2000LED convection heater, shows on the LED display which setting you selected. You can choose from 3 power settings: 750, 1250, and 2000W. This allows you to heat up poorly-insulated rooms up to 16m2 and well-insulated rooms up to 23m2. With the dial on the heater, you can set the temperature. Thanks to the thermostat, the heater turns off automatically when it reaches the desired temperature. The built-in fan spreads the heat through the room faster. That's useful, because the heater doesn't have to be on as long and you use less energy. If the heater falls over?, the tip-over protection turns it off right away.
