Works great got a 6000 Sq ft shop heats great.20 degrees outside should bought long time ago.
Thank you for the inquiry. The Mr. Heater 400,000 BTU forced air propane heater has a run time of about 17 hours on LO, and 10 hours on HI when connected to 2-100lb propane tanks. Have a great day!
Thank you for the inquiry. No, you are only able to use the included hose and regulator attached to 2 unregulated remote 100lb LP tanks as a gas source for the heater. A regulated fuel source will not allow this heater to work. Have a great day!
