This stove is equipped with 3 tubes that are safely behind a grid. You decide how warm you want it to be, because this heater has 3 heat settings: 400, 800 and 1200 Watt. Due to the halogen effect, that heat is also available almost immediately. When you turn it on, only the middle tube radiates heat. You can also let the top and bottom tube give off heat as needed. The heat from this stove can be spread well throughout the room. The device stands on a rotating base. If desired, it can move from left to right (oscillate). The electric heater is compact and portable. The dimensions are: 27.5 x 12.5 x 48 centimeters. With the handy carrying handle you can easily take it with you from room to room.
