HOT ! Open-Box: QMark Electric Commercial Heater

Designed for commercial and industrial areas, the QMark Electric Commercial Heater efficiently heats up to 250 – 500 square feet. This 240/208 volt hardwired heater features ceiling and wall-mounting options and features a built-on thermostat control and fan-only option. Heating between 40 – 90 degrees F, this 22-pound commercial heater extends the life of the heating element with 210 CFMs of airflow.

Other features include overheat protection, fan delay, long warranty, and more.

Ceiling/Wall Mountable + Plug Assembly

The included stand and swivel bracket allow for ceiling or wall-mounting installation. Ceiling mount the heater using the 16-inch on center holes, and for wall-mounting, use the 4 included keyhole slots. The swivel bracket moves the heater and heat direction horizontally or vertically—depending on how it is mounted.

If you don\'t want to wire this heater into place, add the plug assembly for simple plugging into a 6-50P outlet.
