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.

Mr. Heater Big Buddy Portable Heater is rated 4.7 out of 5 by 900.
Rated 5 out of 5 by from Loved it It was perfect for our trailer for camping it kept as nice and cozy warm In Colorado

Rated 5 out of 5 by from Great for winter events! Love that we can use this at indoor unheated events. We have chosen to use the adapter hose and a 20lb tank to avoid the waste of a bunch of small bottles and frequent bottle changes. This allows us to make it through a 2 day event without changing tanks. It holds up well when fairly protected from breezes. It will blow out if the breeze is too strong. The fan feature is nice if you are in a smaller space but in a large space is unnecessary. Well worth the money and we liked it so much we bought a second one!

Rated 5 out of 5 by from Perfect Size for Small Shop The Mr. Heater we purchased is just right in our 20X20 shop. We purchased a longer connection hose to connect the heater to a propane tank and an adapter for the blower. The hose and electrical cord are not prohibitive in the space where the heater is used and allows for us to run it on high most of the time. A good looking, efficient little heater that keeps us warm enough to grill out in the dead of winter. We'd purchase it again.

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

We have a smaller version of this heater and even in an open area it shuts off every few minutes. Why does it do that and does the the big buddy heater do the same Thing?

Asked by: Bryan Sweet
It may be the pilot light is not heating up the thermocouple enough. Try shielding the heater from the wind and see if you can check the pilot flame for movement. Rich Mr Heater

Is this heater safe to use in a car

Asked by: Sara66

Running the unit on high and using a 30lb tank, what is the expected run time of this heater?

Asked by: L2629s
the tank will empty rapidly within 4 to 5 days depending on use during the day. Use the first tank and record start time until it goes empty. Doing this homework will prepare you better. I always recommend a stand by second tank. Rich Mr Heater

is a filter required when attaching a 20 lb tank to this heater

Asked by: sherlock 1
Thank you for your inquiry. A filter is required if you are using the F273701 hose or the F273702 hose. No filter is required with the F273704 or F271803 hose.
