Device description

The electric heater serves to generate and distribute warm air, e.g. in interior spaces.
The device generates heat by means of a heating element. The air surrounding the heating element is heated. The heated air is blown into the room by a fan.
The device is equipped with an integrated thermostat and so generates a constant flow of warm air.
Fan operation without heating function is also possible.
