The Mr. Heater Forced Air Propane Heater has a heavy-duty design built for the jobsite. It comes with a standard hose and regulator and all the safety you would expect from a Mr. Heater product. Equipped with a factory installed high limit switch and thermoelectric safety valve, you can feel comfortable using this heater on a jobsite. Just plug the heater into a 110v outlet, hook up the included hose and regulator to a 20 lb. propane tank or larger (not included), and you are ready to take the chill out of any job.
