These baseboard heaters use convection to circulate air. By design and proper placement under a window area, the electric baseboard case causes air to flow naturally. The cold air falls from the window area as the warm air rises from the heater, causing the air to tumble gently throughout the room. Features oversized high temperature limit switch with full length capillary sensor tube. Durable steel sheathed element, rugged steel construction, and powder-coat finish. Easy installation and quiet operation make it the preferred heater for bedrooms. UL (Underwriters Laboratories) and ULC (Underwriters Laboratories of Canada) listed. Thermostat not included.
