Mr. Heater 12K BTU High Intensity LP Radiant Auto-Spark Industrial Heater
The 9120 Series Heater comes ready to run at 120,000 BTU/hr, but includes a kit so you can easily adjust it to 100,000 BTU if needed. Unlike traditional heaters, this infrared model focuses heat directly on people and objects at floor level—those surfaces then warm the surrounding air. It’s a great solution for open, drafty spaces like loading docks or mechanic bays where doors stay open during cold weather. Even in the wind, it provides a sun-like warmth to workers and equipment on the ground. This model uses a reliable spark ignition system and comes with a 120V / 24VAC / 40VA transformer. Backed by a 10-year pro-rated warranty on the burner and a 1-year limited warranty on gas controls, it’s built to last. Be sure to check the manual for installation and clearance guidelines.

- Heatstar High Intensity Heaters have multiple outputs per model series
- Additional burner orifices are included that enables the installer to increase or decrease the output of the heater
- Spark ignition heaters ship with 40VA transformers
- Non-corrosive materials are used throughout heaters construction
