Feature: silent-flowTM - natural heating technology - NO FAN! * Wall-mounted electric convection space heaters that use less than 1/3 of the energy typical space heaters use. An environmentally-responsible alternative to 1,500 watt space heaters. * Less than 24″ square, and are mounted 3/4″ off the wall to create a convection heat channel. The air between the wall and the panel is heated and rises, drawing cool air from the floor, thus silently circulating warm air throughout the room. * Easy to install. * Can be painted to match any décor. * Plugs into a standard outlet. * Canadian model in bi-lingual packaging available (C400S). * UL 2021 certified by Intertek (ETL).
