Unit heater is an electric heating product fixed on a wall or a ceiling, suitable for workshops, garages, basements, and drying rooms, etc.
Unit heater creates air circulation through the rotation of fan, to promote air heating. It is suitable for places requiring discontinuous heating. 
The product is equipped with a switch; if it is installed too high to operate directly, the wire control type whose switch is installed on a wall can be considered when you place an order.
In places needing ventilation, the equipment can be connected to a fresh air duct; fresh air volume can be adjusted via the air valve.
The product is fixed on a wall or a ceiling, which saves ground space. If your unit heater is to be installed on a ceiling, please clarify it when placing an order.
