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

Reviews

Mr. Heater Big Buddy Portable Heater is rated 4.7 out of 5 by 1341.
Rated 5 out of 5 by from Keeps your piggies warm! My son in law used mine for a late season (auto) race on a flaggers stand to keep his feet warm. It was colder than a well digger's shovel that weekend. In the two days of racing, he used two sets of batteries for the fan, and eight bottles of propane, but his piggies were warm the whole time. The stand was enclosed just about up to his waist, and he said the temp. below was considerably warmer, so he ducked down between races. Yeah, we'd say this works pretty well in a real cold situation!

Rated 5 out of 5 by from Works Great! I used the Big Buddy to keep warm as I replaced the brakes on my car. It was a cold day in March and had to keep the garage door open. Big Buddy kept me warm the whole time.

Rated 5 out of 5 by from Great little heater This is a great little heater. I use it to heat my 24 X 24 shop and it works very well. I bought it from TSC because I understand TSC is the only place that sells the model with a fan.

Questions & Answers

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
