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 Works great Got this for me and my wife so we can hang out on the porch on cold nights. Plus can bring it with us camping or in case power outage and need heat. Worked great on the porch so can only assume it will work for all our needs.

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

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.

How does this unit protect from carbon dioxide build up in an enclosed space?

Asked by: Frankf
Protection comes from the sensors that shut the heater down. However while it burns oxygen and produces C02/ CO .. it does so with the highest efficiency at 99% . Given that a burner needs ventilation and monitors all precautions are on the table.

Does this heater have a thermostat? When it says 4,000 to 18,000 BTU, does that mean you can adjust it to any output in between those extremes, and it continues to burn at that level no matter how cold or hot the room is?

Asked by: Farmerdoug7
Hi Farmerdoug.... the buddy heaters have low or higher settings where the valve allows more gas through. The heater is built to be manual and turned off when you are not near it. Rich Mr Heater
