Description

For chilly deck parties, icy days on the lake, or cold nights at the campsite, the Portable Buddy is the perfect companion. The radiant burner acts as your own personal fire pit, with two settings giving up to 9,000 BTU of heat. Connects quickly to a 1-lb propane bottle—or to a 20-lb tank using Buddy accessories—so you can spend more time doing what you love. Speaking of time, a 1-lb bottle will last you up to three hours on the high setting, so the enjoyment (and warmth) will last. With the heaters’ Life Safety System you won’t sweat too much knowing the oxygen depletion sensor, thermal shut-down system, and tip-over switch are keeping you safe. No matter how you spend your time outside, don’t forget to bring your Portable Buddy.

  • An Amazing, Robust and Powerful Portable Propane Heater; I Use it Daily in an Outdoor Greenhouse Dome Tent Office Space
Color: Red Style: Heater
I have, over the past few years, grown tired of trying to use a small portable electric heater (with two heat settings, rated at 850W and 1500W) to heat an 8.5 x 8.5 foot greenhouse dome tent (the ceiling of this dome tent averages 7' to 8.5 feet in height) that sits in my backyard and has been adapted for use as an outdoor office and meditation room. This outdoor dome tent, which occupies about 72 sq. ft., and about 585 cu. ft. of space, and which has translucent plastic tent walls, sits on the ground, and the floor is a tarp sitting on the ground, covered with some old carpets for a bit of comfort. This dome tent is entirely uninsulated, and, due to the translucent walls that easily allow heat to escape even in the near-infrared (NIR) and visible light regions of the spectrum, it offers even far less insulation than would a tent structure of the same size/volume that used an opaque material such as green tent fabric. This dome tent is equipped with eight zippered screened windows (four near ground level, and four at a height of 6' above ground) and I always leave each window partially unzippered year-round to allow for the flow of fresh air into the dome tent; this is important at all times anyway for adequate ventilation, but it becomes doubly-important when using a portable combustion heater such as this heater inside a dome tent such as this! So, as a result of the factors that I have discussed above, this structure has always been somewhat of a challenge to heat using the 1.5 kW electric heater whenever outdoor temperatures have falled significantly below about 55 degrees F, and it has been impossible to get the interior to anywhere near even 70 degrees F when outdoor temperatures have dropped to 50F or below. So, I finally decided to stop using the portable electric heater and to upgrade to a protable propane heater that was rated and certified as indoor-safe, and that could deliver at least 8,000 to 9,000 BTUs of heat. I finally purchased (via Amazon Marketplace) this Mr. Heater MH9BX portable propane heater, which has heat settings of 4,000 BTU and 9,000 BTU, after careful research into each of the various brands and models of portable propane heaters available on the market. I particularly liked the stable and robust design of this heater, and the fact that it has auto-shutoff for tilting, auto-shutoff for low oxygen levels, and also because of the pilot light and the built-in piezoelectric igniter. At the same time that I ordered this heater, I also ordered a Mr. Heater 12; propane gas hose, and a Mr. Heater inline propane gas filter for use with it. When the unit first arrived, I tested it for a week using a 1 lb. propane tank as the propane fuel source, and then, when that first tank had emptied, I installed the propane fuel filter and the 12' hose running to a 20 lb. propane tank outside the dome. I am extremely pleased with the performance of this heater. It is easy to use, and it produces a lot of heat, far more than my old electric heater did on its high power setting of 1500 W. In fact, I have run tests over the past few days (late October 2013, at an altitude of 1,000 feet in the Appalachian mountains, where we live) in the early morning hours, at about 4 AM (three hours before sunrise), where outdoor temperatures were about 36 degrees F with a 2-4 mph wind, and where the starting interior temperature inside the dome tent was also 36 degrees F. Using this heater on the High heat setting (it is rated at 9,000 BTU at this setting), the interior temperature of the tent was raised to above 70 degrees F within 6-7 minutes from start (this is amazing to me!), and was raised to 82 degrees F within 25 minutes of start; the interior temperature finally stabilized during each test run at about 83 degrees F while the outdoor temperatures were still at 36F. Given the fact that this dome tent has a lot of interior volume for its floor dimensions, and also because this dome tent has very poor insulation (the average insulation rating for the translucent plastic tent material on the walls and ceiling is less than 0.1 R, and the floor, consisting of a tarp and some old carpets sitting on bare ground, also has about the same terribly poor R rating, and also beause of the fact that I always leave all 8 zippered windows in the dome tent partially cracked, I am amazed that this little heater is able to heat the interior to of this structure, in the middle of the night (therefore there is no incident heat from sunlight entering the structure) from 36F to 83F in a bit over a half hour; this is an increase in interior temperature of 47 degrees F (over outdoor temperature and over interior starting temperature) in a structure that is entirely uninsulated and that loses heat very rapidly! In fact, this is an acid test for a heater such as this, for this is a kindof worst-case test for a portable heater! My above-cited tests, along with others that I have not enumerated here, show me that this heater, on the High heat setting, should be able to keep the interior temperatures of this totally-uninsulated dome tent at a comfortable level down to outside air temperatures of around 20 degrees F, and should be able to keep the interior temperature at "usable" levels down to outdoor air temperatures of below 10 degrees F/ If I could give this little portable combustion heater an Amazon rating of 7 stars instead of 5 stars, I would do so! And now, since I am a scientist and an engineer, let me share a few caveats with you about the use of this heater, and of ANY portable propane heater: Particularly if using this heater indoors, you will want to be absolutely sure to follow the manufacturer's safety recommendations to carefully check all propane gas connections for any possible leaks after installing, and to check them again prior to each use, tightening connections as needed to eliminate even small propane gas leaks. When you are first starting the stove after having installed a new 1 lb. propane tank directly (i.e,. no hose used) to the heater, bear in mind that the pilot light will not immediately light, and that even when it first lights, it will likely go out (i.e., extinguish) a few times for the first 45 to 60 seconds, because of air present in the internal propane gas line. Thus, you may need to hold the pilot light control down for a few seconds to purge any air present in the propane line before the pilot light will stay lighted. In other words, after having changed tanks, remember to bleed the fuel line by holding the pilot light control down prior to sparking, else you will be "wasting" some sparks! And, of course, once the pilot light has ignited and stayed lit, it is important to hold down the pilot light control for at least 30 seconds until the internal pilot light safety thermocouple has warmed up sufficiently to allow the pilot light to stay lit. When you are first starting the stove after having installed a new external propane tank (usually a 20 lb. tank) using propane gas hose (they are available in lengths ranging from 5 ft to 12 ft) remember that ths hose will, at first, also contain a lot of air, and thus you will wish to bear in mind that the pilot light will not immediately light, and that even when it first lights, it will likely go out (i.e., extinguish) repeatedly a few times for the first 60 to 90 seconds because of air present in the internal propane gas line. Thus, you may need to hold the pilot light control down for a bit seconds to purge any air present in the propane line before the pilot light will stay lighted. Once any stray air present in the propane gas line has been cleared, the pilot light will then stay on continually. In other words, after having changed tanks, remember to bleed the fuel line by holding the pilot light control down prior to sparking, else you will be "wasting" some sparks! Late Update, as of October 27, 2018: This amazing little heater is still working perfectly! I love it! ... show more

  • A Must-Have for Winter and Overlanding – Quick, Efficient, and Reliable!
Color: Red Style: Heater
The Mr. Heater Portable Buddy Heater (MH9BX) is easily one of my favorite overlanding products! I first discovered this heater through the Camping With Steve YouTube channel, and I can see exactly why it’s so popular. This little heater packs a serious punch, offering 4,000-9,000 BTU of radiant heat, and it’s safe for indoor use, which is perfect for camping or overlanding in colder conditions. What I really love is that it runs on the same 16 oz propane mini tanks that power my Coleman Stove, making it super convenient to use with the gear I already have. The performance is absolutely impressive. The heat kicks in quickly, almost immediately after the pilot light turns on. Within just a few minutes, the area around it is toasty and warm. It’s amazing how such a compact heater can heat up a small space so efficiently. It’s also incredibly clean and quiet once it’s running—aside from a very slight propane smell when first lighting, I barely notice it after that. It’s the perfect addition to my setup when I’m in the middle of nowhere and need to stay warm. In all seriousness, other companies should take notes on this heater’s design and materials. It’s clear that a lot of thought went into making it durable, portable, and easy to use. The build quality feels solid, and I trust it to keep me warm during my overlanding trips. It’s one of those products that you never knew you needed, but once you have it, it becomes essential. As a loyal customer, I can honestly say I’ll be using this heater for a long time. It's a lifetime keeper for me, and I wholeheartedly recommend it to anyone looking for a compact, reliable, and efficient heating solution for their camping or overlanding adventures. ... show more

  • Great little radiative heater
Color: Red Style: Heater
The thing to know about this heater is it throws off a lot of infrared radiation, which is the primary mode of heating. It is like having a little portable Sun with you. Like if you go outside and it is cold and cloudy, you will feel cold. But at the same outdoor temperature and the Sun beating down on you on a clear winter day (if you have clear winter days were you live), you will feel a lot warmer. A fun little thing to do if you have security cameras with night vision, light this up in view of one of these security camera's at night. It is brilliantly bright and everything in the line of sight of the hot plate on it nearby is brilliantly lit up. With the naked eye at night, you will just see a dim red glow, but the security cameras will see a blindly bright light as it is in IR night vision mode and the black body radiation is primarily in the infrared spectrum. This means when you are outside, basically regardless of conditions, as long as the conditions are good enough for this to work, it will be heating you up. You can even say leave this outside your tent and as long as you are setup to let the infrared light in, it will warm up the inside of your tent and any infrared light hitting you from this will warm you up, say you are laying there in your sleeping bag. It is almost like magic as most people are used to thinking about heating in convection terms while this primarily operates in black body radiative terms. I am not saying sit out there butt naked in the snow with this being your only device to keep you warm, but it is a greet supplemental heat source to help you keep warm when you are doing something sedentary outside in the cold. The one gripe I have about this is the flame is unstable and noisy on the low setting. This works best at the high setting anyway, so probably what you want to do and just forget about the low setting. If you use this with a larger tank with a hose, you may want to plan to shut the main valve off on the larger external tank a couple to a few minutes before you are done using the heater so that there is time for a pressurized hose to purge. As this only lasts a few hours on a 1 lb tank, you can quickly end up getting into using larger tanks with this. ... show more
