Item Information

This patented radiant 4000-18000 BTU Liquid Propane heater connects directly to two 1 lb. cylinders. The Mr. Heater Big Buddy Portable Heater is the perfect solution for heating enclosed spaces like cabins up to 450 sq. ft. An integrated fan increases the heating capacity of this unit, blending radiant and convection style heat to give you the best of both worlds.

  • Two swivel regulators give you the ability to adapt usage from disposable cylinders to a remote gas supply with the purchase of a single hose and filter
  • To light the unit, simply push and rotate the knob - the built-in Piezo sparking mechanism will take care of the rest
  • With the Oxygen Depletion Sensor (ODS) and accidental tip-over safety shut-off, you can be sure that you will enjoy years of comfortable indoor safe heat
Not for sale in Massachusetts or Canada.

Rated 5 out of 5 by from Extremely Satisfied! I bought my Mr. Heater Big Buddy propane heater mainly for a back-up heater in case we lose electricity. As luck would have it, two weeks later our electricity didn't go out but our heat pump did. I used the big buddy heater for two days in temps that got as low as 7 degrees. It heated my living room, kitchen and hallway to a very comfortable temp. Highly recommend.

I bought this heater and the filter and hose and we love it and the box says it's indoor safe it's perfect I just hope it's actually indoor safe as I have a one year old and like as far as it not letting harmful fumes into our home it is safe right.?

Asked by: Code
Thank you for your inquiry. This heater is certified for indoor use. There is an oxygen depletion system that is installed on the unit that shuts the heater off if the oxygen drops below 18%.

I have a smaller version of this heater I use in my hunting blind. it keeps me warm but on colder days I can get cold on the opposite side of the heater. Would this heater be too big to use in a hunting blind? My blind is 4' by 4' / 6' height.

Asked by: DanR65
I wouldn't recommend it ... you are something smaller than a closet.... the mh12 hunting buddy puts out more heat than the mh9 and is only a little bigger. Rich Mr Heater
