This is the portable radiator with a patented heat flow system that provides consistent, thorough heating of a room. The unit has seven built-in vertical thermal tunnels that enable radiant heat to rise faster than typical oil-filled radiators, resulting in 66% faster, more even heat distribution in rooms up to 144' sq. Unlike noisy fan-driven heaters, this superior model has a silent-yet-powerful 1500-watt heating element and a digital thermostat that maintains the preferred ambient temperature. Four casters enable ease of movement, it is permanently sealed with diathermic oil so as to never requiring refilling, and has a timer with 96 settings. A built-in sensor shuts off power if the radiator is tipped over. Includes three power settings. 26" H x 14 1/2" W x 10 1/2" D. (25 lbs.)
