The Register Plus 14 in. x 7-3/8 in. 2,000-Watt White Fan-Forced Wall Heater offers up to a 300 sq. ft. heating area capacity with a durable, commercial-grade steel element. This electric wall heater features a squirrel cage blower that helps provide increased airflow, resulting in lower surface and air-at surface temperatures and quiet operation. Often chosen for its similar appearance to a central system register vent, the Register operates exclusively at 208-volts. For greatest energy savings, use with an electronic, programmable wall thermostat sold separately.
